Title: A7rII review - single card.
Post by: David Anderson on August 22, 2015, 02:31:11 am
Thanks for the review Michael, I've been waiting for it.

So, it looks like an amazing camera from the spec sheets and certainly everyone who's review it seems pretty impressed.
The recent lenses to be released from Sony and Zeiss are also reading up pretty well - particularly the 90 macro.
In short, Sony is a very tempting proposition now.
But I can't get past the single SD card slot having had dual CF/SD card slots in my cameras for many many years now.
Though I've only had a few card problems since the start of digital, those problems have all been with SD's
Does this worry anyone else ?
Personally, I can't imagine shooting something important without that back-up, though maybe I'm overly cautious or even paranoid.. lol

Same concern here.

In my book it rules out the a7rII for mission critical applications where the higher bulk of my existing gear isn't a major problem (and bulk has never been a major problem objectively speaking).

That's fine, v3 or the a9 will for sure fix that. I'll happily let the hype crowd fund the R&D activity at Sony until they get it really right and will continue shooting with my highly performing gear in the meantime. ;)

Cheers,
Bernard

Hi,

Phase One cameras are also single card, although being regarded fully professional. Yes, dual cards would be preferable, no doubt.

I dont really think the A7 series are professional cameras, the A7 designation is a clue, all "professional" cameras from Minolta/Sony had a 9 in their names, like A900, A99 and A9?

Best regards
Erik

We've already been through this in an earlier thread.

There is no MILC format camera that has dual card slots.
There's not been a digital Leica M with dual card slots
If you need dual card slots then buy a larger DSLR with all its limitations.

ITM, I'd no more think of going on a 'mission-critical' shoot with a single cam any more than I would relying on a single form of backup - dual card slots included. If I wanted the cam, for the cam's sake - I wouldn't be deterred by the single card, I'd look for an alternate safety strategy.

The rendering of greens, green yellows  and browns is completely different between the Pentax and the Sony. The Sony has "global green".
Look at the image for a few minutes, and the differences will start to pop out, and make the Pentax image go "3D" as the forest acquires depth.

how did you exclude raw converter + whatever camera profile was used here (that is not to say that they certainly have different CFA properties) ?

I'm not "excluding" profiles, these are the published images, with whatever real-life tools have been employed by this reviewer.
Presumably, these are the colors *users* will be getting.
Each camera has strong points and weaker ones; the Sony has a  zillion ISO, 40MP resolution, 4K video, a 5 axis stabiliser, a light portable body, and a good price point. Let us give the more expensive, large, heavy and conservative Pentax its due, *in these pictures* it shows  better color discrimination in the greens, giving more depth to the forest. Possibly a better lens or a different Raw processor on either camera would change that. There is also probably Jpeg on both, to set a baseline.

Give Michael his due, he publishes honest real-life comparison pictures; it is up to us to each of us decide what we see in them.
And by the way, as you know, I was an ICC member, and a consultant to Xrite, so I am familiar wiith profiles.

Edmund
PS. I wish Michael posted the raws or at least Jpegs somewhere.

Did a discussion recently not point out the value of monitoring the channels closely and using a CC filter for the heavy green channel if necessary and that the WB had a major role in colour, particularly green, discrimination?
Michael does point point out that in the tower test both were set to daylight (although that point could differ between the cameras ? ) and the colour "rendition" was very different, (as was the contrast) I assume he used the same RAW processor or perhaps OOC Jpegs, does he say? but of course in RAW the profiles will vary so his comment is perhaps not helpful.

The single card slot is the number one reason many professionals (that I work with...)will not seriously consider the Sony A7 range.
It was an obvious and easy addition for Sony to add to the A7RII, the fact they didn't  says a lot about who they aim the range at.

The battery life is the second biggest issue for me.
The lack of repair services is the final hurdle, it's not a cheap camera by any measure, who's going to fix it when it breaks?

Chris,

 This just confirms my impressions from other pix posted on the web, before Michael's test - the difference here being that thanks to Michael we have a contemporaneous comparison image from a "benchmark" landscape camera.

 In any case, this seems  at most a minor "look" issue. And it might well be a non issue and a better profile or some Raw magic may improve matters. We'll find out in due course. For the RED Dragon, filtering does help with a color issue (http://www.newsshooter.com/2015/06/06/achtels-trueblue-optical-filter-for-red-dragon-and-red-epic-cameras-removing-unwanted-magenta/):

(http://www.newsshooter.com/wp-content/uploads/2015/06/Screen-Shot-2015-06-06-at-9.49.44-AM.png)

 It will be interesting to see whether Nikon versions of this sensor behave the same ie. have the same CFA.

 BTW, does someone have experience with the H4D60 or H5D60 vs the 40 or 50 vis à vis green discrimination? I saw some 60 pictures once which were very good.

The Sony color look (probably their Bayer filter choice) is cold-looking. Tough to correct easily in post. And it seems to be across their line of mirrorless cameras. Same in the NEX series I am most familiar with, and that issue is not minor in my book. The look of my 10-year-old EOS 5D still wins everyday over any Sony shot I have seen.

I find the opposite. Myself and everyone I've asked who has expressed a consistent preference "look" wise rather than subject wise prefers my Sony A7 images to my Canon 5D images.

I shoot raw and process in CS5 with no heroic measures. The Sony A7 files are IMO gorgeous. 5D files are merely nice :D

Hi Chris,

Only up to a point. I'm sure that e.g. the Holga shots were not because of it being a superior camera and optics to do the job, but because it was easier to get a certain 'look' (and was less likely to get stolen). Camera's are 'enablers', a tool to allow or assist in achieving a goal. For example, one usually cannot shoot a good/sharp/detailed distant 'Birds in Flight' image when the camera does not allow to use a tele lens and high enough shutter speed to achieve a close-up view of the bird that's not totally blurred by motion.

Setting the goal, and executing the creation (assuming the camera allows to do it(!)), and post-processing to achieve the creative intent, are up to the photographer, I agree. But if the camera doesn't deliver the raw material that's fit to work on, then there is something wrong, and it's not the photographer but his gear.

As to a single card, I do not think that it is necessarily a showstopper. I do not use my current dual card camera capability to shoot duplicates (but rather have it set up to avoid having to switch out full cards in the middle of a time critical event), but it may be useful to do so, which makes it a good option to have and activate when a bit of additional assurance is required. Useful additional feature, yes, a showstopper, no.

Cheers,
Bart

Hi Chris,

You may have not followed Iliah Borg a long time as I have. Otherwise you would know that he favours magenta filtering in general for most cameras. I first stumbled on this when UniWB was discussed to increase accuracy of histograms on digital cameras and Iliah suggested the use of a magenta filter to balance out channels. Long before A7...

Best regards
Erik

Indeed, the penalty of posting one liners, they are great for point making, but not subtle. I of course agree that the camera does matter but in the euphoria surrounding new equipment it is often put on one side that there are other factors involved. BC is rather good at making that point, better than I.

Post by: ErikKaffehr on August 23, 2015, 06:31:10 am
Hi,

This is quite a bit off topic, but it seems that you refer a lot to posterisation on Sony found by Diglloyd and the comments about it. As it happens, I found a case of bad posterisation on the P45+ I have, using Capture One. Now, I normally don't use Capture One but I was checking out the image in C1 as I have seen posterisation with the DCP profile I was using in Lightroom, my preferred tool.

What I have found was:
LR, DNG Profile Editor 131225Posterisation
LR, Adobe Standard ProfileNo posterisation
LR, DCamProf ProfileNo posterisation
Capture One, daylight profilePosterisation

Here are all images: http://echophoto.dnsalias.net/ekr/Articles/MFDLook/20150407-CF046278.jpg

And here is the raw file: http://echophoto.dnsalias.net/ekr/Articles/MFDLook/20150407-CF046278.iiq

I think this illustrates pretty well that colour management can cause posterisation, even on 16 bit P45+ raw files and Capture One is in no way immune from creating posterisation artefacts.

Best regards
Erik

That's where I read it, thank you Erik.

I fact out of 150 TB's of raw data we've produced the only corrupt files I've seen are about two dozen 1ds2 files because the processor on some cameras couldn't keep up with the chimping (so Canon slowed the camera down) and one RED 1 file that went totally funky because we kept the camera running on set to drag in and shoot some pickup on a hot day for way too long.


Sounds like a very good run.
I've had 3 Sandisk SD's physically break (many years ago admittedly), 1 Lexar SD not work from new not so long ago and lost one SD (back-up card) after a very long shoot.
Never had any issues with a CF card.

Obviously, the chances of something happening are quite low, but I really like the idea of dual cards with one recording JPEGS as a back-up - just seems like common sense to me.

Hey, I looked up the meaning of "Cooter". I always thought it was a barnayrd bird, now I know different :)

Anyway, methinks that when you have a "tech" to do x, y or z, prepare and check the cards, then your perspective on "professional" is very different from that of the guy with a rucksack who needs to do a whole marriage alone. Of course workstations which are not contaminated with crap will work better but the mom and pop shops cannot afford them etc. The discussion of whether 2 cards are necessary is probably BS, but yes - cheap shooters working an event alone on a sunday or journalists/landscape/travellers in some remote spot actually need reliability more than the cooter with a vanful of equipment, camera backups, and aides attending who can be sent to fetch a spare body or lens from a rental house - which, let us face it is is what really happens in a metropolis: You just send an assistant in a cab to borrow/rent a spare body or lens while the crew gets a beer, lighting is repositioned, dresses adjusted and makeup is refreshed. Because once the shoot goes large it costs, and so there is a Plan B. Let us not forget that the humans break at least as frequently as the equipment.


JMOGP (just my own ground level perspective)
Edmond.



If one card slot turns you away, so be it, but i've shot a billion still images with cameras that do and do not support two cards and never thought about duplicating the images in camera.

We usually have a tech, we're checking as we go in the selected processor because that's the ONLY way to be sure.  If not I'll personally check it as I go and I never shoot a card to full anyway.

And for the record we're not sipping mai tai's waiting on the results of what the tech says, as today every still session for commerce allows about 11 minutes of shooting time.

I fact out of 150 TB's of raw data we've produced the only corrupt files I've seen are about two dozen 1ds2 files because the processor on some cameras couldn't keep up with the chimping (so Canon slowed the camera down) and one RED 1 file that went totally funky because we kept the camera running on set to drag in and shoot some pickup on a hot day for way too long.

No problem with 9 models of canon, 3 phase, 4 nikons, 2 leicas, 1- sony video, 3-REDs (except mentioned), 2- Olympus, 3-Panasonic and 1-Kodak/Nikon.

But to make sure we don't have issues we rigorously match cards or ssds to cameras, format three times, then test, then format again.

When tethering have clean computers, make sure all connections are viable including backups and test those in the "try to F*&$ it up" process, so we're prepared for any issue.

In other words we go out 100% prepared and since we own our own stuff we know it's right and have backups for everything.

We also pay close attention to card readers, drives, and cards, only using lexar, sandisk and RED SSDs.  

I've tried three transcends and had all three go glitchy and if we have a card that doesn't test well we either return it, or throw it in the rubbish bin.

Early on in digital I would get calls from guys that just bought a leaf, a phase, a canon or something screaming they can't download, or tether, but they were using older machines, not enough power, cheap drives, computers loaded with their "social" and web software and having some semi learned assistant doing the dumping and copying.

In other words they had already invented the perfect storm.

Look I'm not selling Sony cameras,  heck, I'm not selling anything, but most equipment is only as good as the people using it and the levels they go to, to protect their imagery is much more than having a camera with dual slots.

i think he was saying thay he's shot more sd cards - in a professional enviroment - than we've had hot dinners, and that we shouldn't get hung up about it, they are reliable but just use a bit of common sense, buy good cards, fomat well, change often if you can't backup, don't mix on other cameras, etc., all very good advice.

I agree that dual card slots would be ideal, but my take is that SD cards are extremely reliable so it's not much of worry. When using my D600 I use the second slot for overflow, not backup. In many years of shooting I have never had a single SD card error or problem. My approach is to buy only brand name cards and replace them every year or two. And use common sense - don't swap cards while standing on a sewer grating, keep your full cards in a safe and protected place, and so on.

Hi,

I had two images that have been corrupted in ten years of shooting. Both were sequential on the same CF card.

One thing to keep on mind that memory cards are just one part of the imaging pipeline that can go bad, and a tiny part at that. The best way to achieve redundancy is shooting with two different systems.

Best regards
Erik

That's all good info and encouraging, and yes there's a lot more to protecting your imagery than having dual slots... but it's surely a good start.

I've never had a card fail either, except in the early days of the Sony Micro Drives.. (remember those!)

But my house has never burnt down either but I still pay the insurance premium every year.

For the RED Dragon, filtering does help with a color issue (http://www.newsshooter.com/2015/06/06/achtels-trueblue-optical-filter-for-red-dragon-and-red-epic-cameras-removing-unwanted-magenta/):

Hey Edmund,

I always thought that the RED in RED Dragon was a nickname chosen for its over the top red CFA response, unrealistic as it is compared to the human visual system's response to it.  However, the RED Dragon has virtually nothing to do with Sony's CFA choices.

I appreciate your subjective, color-consulting, ICC-belonging opinion but until someone produces an absolute QE, spectral power distribution or similar measurement for the a7RII showing it to be much different from current Nikon and Canon DSLRs', it remains just that. Can you produce such comparisons? 

Until then,

Jack,

 You are doubtless right that I am an old idiot with the IQ of a carrot. In fact, every day, I get up, look down, see only belly, and think "I'm a fat old idiot with the IQ of a carrot, what happened, only yesterday I was a young and thin idiot". I am ever so thankful to you for independently confirming my observation.

 Now, I am however a bit of a smartass. And so I'll turn the question round: Why should such a revolutionary product, with such a fast sensor, be similar to those that came before?  Can *you*  produce the graphs? :)

Thanks for the review Michael, I've been waiting for it.

So, it looks like an amazing camera from the spec sheets and certainly everyone who's review it seems pretty impressed.
The recent lenses to be released from Sony and Zeiss are also reading up pretty well - particularly the 90 macro.
In short, Sony is a very tempting proposition now.
But I can't get past the single SD card slot having had dual CF/SD card slots in my cameras for many many years now.
Though I've only had a few card problems since the start of digital, those problems have all been with SD's
Does this worry anyone else ?
Personally, I can't imagine shooting something important without that back-up, though maybe I'm overly cautious or even paranoid.. lol





Up until about 5 years ago, everything was shot without a backup including film. We survived.

The single card slot is the number one reason many professionals (that I work with...)will not seriously consider the Sony A7 range.
It was an obvious and easy addition for Sony to add to the A7RII, the fact they didn't  says a lot about who they aim the range at.

The battery life is the second biggest issue for me.
The lack of repair services is the final hurdle, it's not a cheap camera by any measure, who's going to fix it when it breaks?

I sent in my A7R to the address listed for warrant and service work and it was back in about 1 week fixed. How hard is that?

I'll assume you two geniuses know what an analogy is  :)

Just in case your serious though... I pay home insurance while not expecting my house to burn down, but if it does I'm covered financially. (yes, you do need to rebuild the house  ::))
I use cameras with two card slots for the same reason, the possibility of a card failure, not neccessarily the expectation.

Two slots alone won't always help, it's also important how they can be used.

My old Sony A850 and A700 both have dual card slots, but you can only use one or the other.
You can't save raws to one and jpegs to the other (or raw and a raw copy)

So to have some kind of insurance you need dual slots and the right firmware to use one as a back-up for the other.


On the flipside my old film cameras only held one film at a time and as mentioned before many MFDB's also only have one slot, so I don't consider this issue a necessity. It's convenient and I wouldn't mind having it, but it's not going to determine the choice of camera I use or take with me.

Now, I am however a bit of a smartass. And so I'll turn the question round: Why should such a revolutionary product, with such a fast sensor, be similar to those that came before?  Can *you*  produce the graphs?

I asked first, therefore I get to ask the first follow-on question :)  What are your thoughts on the color of their other recent products (A7x and/or A9x)?

My thought is that the old A9xx was supposed to be slower than the D3x and have better color. :)

Hi

These things are just tools and as such tools need to be functional, reliable and produce better results than other tools.  The A7RM2 does mostly do that.  Cost is an issue, reliability is an issue, backup is an issue but dual card slots ????

People in my industry lose two pints and blood and keep working, so no we don't fail, unless we're dead so then I guess then it doesn't matter.

J,
 I think you misread - my point is I DISAGREE with the  meme of  "only with 2 slots is it Professional" meme of the OP . Once it is a large shoot, a camera is just one more component in the mix. Camera works, great. Camera or any other hardware breaks at the last minute, there's some backup solution.

 As for people in the industry ... I don't get paid, but the people downstream from me do. When *I* do the occasional "free" shoot for a dress designer or a furniture designer, or a music video,  and it takes one day or 3 days full time and there's a team, it sure costs a lot to do, for everybody else involved. There is a budget, I'm just a zero-rated component of it, while equipment rental, location, makeup etc are budgeted and paid. But I've noticed that the budgeted "professionals" ie. models, sound guys, makeup, are flaky, it's a local attitude. Last time I went to the hospital, eight patents were waiting, and doctor had to be called back from 2 hour lunch by the nurses. Maybe the reason americans are more successful commercially *is* that they work their butt off.

 BTW, here is the person Sony really wants to use their cameras  -attached image :)

 It's Michael's A7RII review (https://luminous-landscape.com/sony-a7rii-review-and-hands-on-report/), there's a 100% side-by side Pentax/Sony comparison image, which you can enlarge in your browser. to get the best impression of the color.
 And if you disagree with my reading of this image, I'm not going to get upset, I might even change my mind :)

While I agree with your disagreement (there's plenty professional camera's that only hold one card and/or one film) the problem with failing memory cards cannot just be solved with a backup in the field. There have been many cases where the card worked fine in the field but once at the computer back in the office the pictures could not be retrieved. Most other components in the chain can be replaced in at the instant they fail (and should be available for a professional shoot) but in case the card fails like I described you're toast.

I agree with your point that these failures are a catastrophe for the lone shooter - although some here seem to say these failures are rare if you can keep card hygiene, that they are caused more by bad quality cards or a card that had its filesystem damaged in a computer.

On the other hand, precisely to avoid this issue, teams the size of those "Cooter" fields have a guy spooling the images to a computer and checking them. In fact, my executive producer had exactly this job on the video shoots he used to do.

A lot of the journos I know, and single shooters, keep changing cards to make sure all their imagery isn't only on one.

That helps, as does shooting with two cameras on everything, but I've found the most peace of mind with the second card.
Also, FWIW, on a lot of shoots, even big ones, I don't need to bring a computer and that frees up a lot of time for shooting.

I always have my Canon and Nikon cameras setup writing the RAW files to two cards. I load the images from the SD card into my MacBook Pro when I'm back from every shoot and one 32GB card is plenty always for me. I gives me peace of mind that I have a backup on the second card in case of card failure. I have experienced one other situation not mentioned (I think as I did read all posts in the thread) and was one time I reformatted the SD card and I realized that I had not loaded the images!! Then I could load them from the CF card. Well that should never happen, of course, but I was tired after days of workshops and my normal routine is to load the images the evening before and I had not done that and I realized after I did the formatting in the morning. A stupid mistake and the second card saved from using recovery software to find the pictures on the formatted card. I has only happened once, though  ;D

Yes i formatted also one time a cf card in my sinar back aftre a long shooting day. Nice moment when realizing that i pushed the wrong button ... But shit happens and is not a reason for me to stay scared now all the times that i'll do it again.
Also i was looking for traffic to the wrong side trying to pass a left driven street in Bangkok and was hit nearly  by some Autobus which came from the other side with 70 Mph... but thats not a reason now only to pass streets in zebra marked zones, but to be a bit more attentive to what i am doing in left drive countries .
For me this card thing is much overestimated and not to buy a cam zherefor is hair splitting. What did you do in film days? What with single card  mf backs?
btw. In 12 years of digital I remember one card failure years ago on a cf 4gb card, and this  files i could recover with some sw tool.

Hans, Rainer,

 These days, I wonder if one shouldn't simply keep the cards safe as storage at least until trip return, rather than reformat them. Thanks in part to the popularity of video and phones, the prices of "slow" SD card have really fallen.

I wonder, how many of you shot with two rolls of film in the same body?   ;D

I know of one instance (and thankfully only one) where I kept shooting and finished what I thought was the roll of film only to rewind, process, and find out later that the film was not advancing at all.  One complete roll of film completely wasted and all those images lost.   Lost pics are not the exclusive domain of digital.

Hi,

Images can always be recovered from a newly formatted card. Actually, a lot of new images can be shot on the card after reformatting and the original images are still recoverable. The memory cells wear out, so the controller tries to spread the images over all of the card, so the memory areas recently used will not used before the card begins to fill up.

Yes, I would suggest dual slots are an advantage. Most MFD cameras are regarded to be professional but usually they don't have dual slots. Pentax 645Z has dual slots, Leica S I don't know.

Best regards
Erik

In the film days I shot with two bodies (kind of miss those Canon F1s with huge drives…), but still once managed to shoot with one body with film, one empty, and when realizing my mistake opened the filmed camera in mid-roll… Shooting with empty camera happened a couple of times in 25 years, wondering if the film was going to never end…

I have not had card failures in almost 10 years now, and by the simple rule of using only best cards (Sandisk), always formatting after use, never manipulating cards in PC and never deleting pictures in-camera I intend to keep it that way. I have shot several multi-week overseas jobs with single slot cameras without backups and without stressing about it too much. I did not worry too much about it when sending 100 rolls of KodaChrome home with a stranger found at the Bankok airport in 1984, something going awry now is certainly less probable. Keeping things simple also gives peace of mind and improves shooting.

I just did that last week with my 5d2. Thankfully I realized about 30 minutes in and could just reshoot right there. I see that my A7RII actually has a custom setting to disable shooting when there's no card. I'm going to activate it.

Film transport issues were a constant irritant with 35mm cameras - and in fact the old box camera I bought a year ago had the transport of 120 film lock up half through the roll.

I could type out horror stories about film until I had RSI or was removed from the forum.. ::)

The worst was having a quick set-up shoot with the Backstreet Boys when they were the thing and getting two very fast rolls through the Blad before it was over.
The first was clipped and then both were processed except there was some sort of tangle in the machine and they came off the racks and were seriously damaged. Luck was on my side however and a couple good frames spared including the clip.

I think some of my paranoia with memory cards actually started that day.  :D

If my camera had two card slots I would probably not use the second.  I would trust solid state memory more than I would trust mechanical elements in the chain like shutters, buttons, PCBs, etc.  Unless you duplicate all of those then you haven't really got redundancy.  Plus you could drop a camera with two cards in over a cliff and it probably wouldn't help you ;)
