Title: New Camera: Canon, Nikon or Sony?
Post by: JoshDuffus on December 26, 2009, 03:06:15 pm
A few years ago I inherited a Konica Minolta Maxxum 7D and a number of accessories and lenses (85mm f/1.4, 24mm-105mm f/3-4.5, Sony flash, wired remote, and vertical control grip).  It's been a great camera, though I had to take into the shop a year ago because of a problem with the autofocus.  It continues to be a great first DSLR, and I've really enjoyed learning so much about photography.  However, one of the things I've learned is that Konica Minolta is no-more (bought by Sony) and Canon and Nikon dominate the market.  My camera is beginning to show it's age (2004) and I'm looking to replace it in the next few months.  My problem is that I don't know what my next camera should be.  I could:

A) Purchase a Nikon or Canon (I'm thinking a 300s or 7D) to have something more mainstream that would also allow me to play with video.  I've got a toddler and a 6-month-old, so the more fps the better.  Most of my family owns Nikon gear so exchanging lenses and flashes would be a plus.

 I could purchase a Sony Alpha 850 for a full-frame sensor, and continue to use my lenses and flash.  However, I'm stuck with a brand with a very small footprint in the DSLR market.

I can see the advantages to both scenarios, but I'm curious as to what anyone else thinks.  I've been shooting pretty regularly for a year or two now and even done some portraits and family shots for friends with good results.  I'd like to take the next step and consider shooting more portraits and weddings perhaps as a side-gig.

Thanks for your input!

I use both Canon and Nikon, however if you have a nice set of lenses, I think staying with the mount makes most sense, and the 850 is a quite nice camera, from all reports, and much more likely than not to be growing in footprint and userbase over the next 4-8 years. Given Sony's size, I'd not worry too much about going that direction, and the camera does most all of what others will do, and some of it a good deal better, particularly in your position from a cost/benefit analysis.

I'm not sure the size of the footprint in the DSLR market should be all that relevant to your purchasing decision.  You've already got an investment in Minolta glass--I'd leverage it unless, you are looking for a specific feature (ie. video) that Sony doesn't offer yet.

In that case, is that feature worth the cost and hassle of getting rid of your Minolta setup and buying more glass for your Canikon?  That depends entirely on your budget of course.

From the cameras you've mentioned, I'd give the edge in video to the 7D.  Nikon's been coming out with some killer bodies, and top-notch high ISO performance; Canon's been coming out with a lot of significantly improved pro glass.

Also consider what your friends might be shooting--basically you can't really lose here; it's nice to be able to share lenses and such with friends and colleagues, so consider what your peers are using as well.

Best,

Thanks fellas...great advise.  I was a little worried about where I'd be in 3-5 years with a Sony body, but it's good to hear that there's a perception that they'll still be around, doing what they do.

Thanks!

The Sony/Minolta is still a viable option as nearly every single lens made for the older Minolta AF SLRs works with it - you just have to buy used or new old stock lenses in those cases.  Obviously Sony wants you to buy their *new* lenses which are identical in almost every way other than the label, so you don't hear about the other 50-70% of the lenses(the old ones that still work with it).

Buy it - save a lot of money and enjoy.   It's a good camera since Sony pretty much has left the same Minolta team in charge and to their own devices all these years(and thankfully listened to them about full frame being a must-have, finally)

Nikon is good - though a bit more money.  You pay a lot but get a lot.  I still like the Minolta look and feel though, but that's my personal preference.  I'd actually rate the two as dead even with each other.

Canon, I have to say I'm not impressed lately with their cheapness and obvious corner-cutting.  That you have to try several of the same lens lately to find a "good" one kind of leaves a sour taste in my mouth.  Though they do take great pictures despite all of the poor quality control and plastic.

Thanks! When I first got this camera and the lens package, I had no idea what a great lens it was.  And when I took the camera to the shop, the girl at the counter raved about it.  Since then, it's become my favorite lens for portraits.  I really love it.

Hi,

Yes, that 85/1.4 is known to be a great lens. I got the impression that the 24-105 may also work well on the A850/A900.

I own several Sonys (A100, A700, A900) and I'm pretty satisfied. I don't think they are better (or for that part worse) than Nikon/Canon stuff. It is a true advantage with body based IS, as it works with all lenses. To my knowledge there are no very large aperture lenses with IS. And IS also works.

The disadvantage with Sony may be that they lens line is thinner than Canon-Nikon and many of the lenses are quite expensive.

Best regards
Erik

Ive been in all 3 camps, I was continually underwhelmed by Canon... bodies, glass, everything, and they're  the biggest footprint in DSLRs. Jumped ship happily to Nikon, and only consider picking up a Canon body for the new TS lenses and alt lens adaption.

Nikon is great, world class glass, and the bodies are nice, but for me, you just don't get enough bang for the buck out of the bodies resolution wise... for what I do at least. D700 high ISO is great, but Low ISO isn't the best, and the lack of rez makes all the great Nikkor lenses sad.
Nikon's high end lenses aren't any cheaper than then Sony Zeiss/G counterparts.

Sony has been able to meet all my needs, the glass line up is world class quality, simply phenomenal, though does need a few things here and there. It really isn't as lacking as you might think. Even if you only consider current Sony lenses. Really all I am missing is a fast wide like a 24 1.4  and a really good fast 50 (the current offerings are fine but not amazing), but G or Zeiss versions of these should be coming in the next year... outside of those, what's really missing besides the long teles and TS lenses?

An a900 and the ZA 24-70 cover most of my needs, then for low light / portraits the Zeiss 85 1.4 and 135 1.8 are just insanely good and worth every cent.

I'll also add the Sony flash system is just awesome. A pair or trio of HVL-F58AM flashes and some stands and you have your studio lighting down.

That said I can't recommend the Sony system enough. Go for it!

Its not as if you will make a profit depending on how much of a market share your camera makes up, so "market footprint" shouldn't matter.  For video get a hd camcorder, they are relatively cheap right now.  I think that 3-5 fps should be enough to photograph the children, but what do I know, I used a Minolta x-700 to do that, without a motor drive.  Things certainly have changed.  I would certainly give a lot of weight to owning Minolta lenses, it would save a lot of money and I wouldn't want to be borrowing lenses, but that's due to my family's dynamics.  If you envy your family's Nikons then maybe you wouldn't be happy with anything else.  Nikon makes at least a couple of very good cameras, if you can afford them.  For me it would come down to money, I don't have the money to afford a Nikon that is equivalent or better than the Sony a850.  If I had the money I would have gotten the D3x.
I don't think that prestige or market share are a major factor in deciding, just capability, use of lenses already owned, and money.

I love this forum.

It's good to hear that a lot of people out there are (happily) shooting with the Sony Alpha series.  I get discouraged with all my friends shooting Nikon and Canon, as well as every photography book and magazine doing this same.  I get the feeling I'm missing something sometimes.  On paper, the 850 and 900 have everything I need and I'm really looking forward to checking them out in person.  I'm pretty happy with my old Maxxum 7D and it'll make a great backup body.

You're right about the lenses I own.  They're both great, particularly the 85mm, and I've got a HVL-F42AM flash...which has been a real eye-opener.  I should probably get another one of those.

Thanks again everyone.

Hi Josh
Until you find a limit with the system you have that you cannot live without I would stay with sony. I am  a long time pro. I shoot canon and leica. I would never switch a system unless I had a need that the my system could not do. Do not worry about what other photographers have worry about what you need. If I were you I would get the sony 850 and use it. 2 grand for a 25 megapixel body that is a bargain. Happy shooting David

This is as close as it gets.  

The only thing about Sony is that you have to also include Sigma and Minolta used and NOS lenses in your searches.  This is a minor concern, in my opinion, since used gear is so easy to find these days.

http://www.mhohner.de/sony-minolta/lenses.php?lg=e (http://www.mhohner.de/sony-minolta/lenses.php?lg=e)
This is the other "master list" online of older OEM lenses.  As you can see, often only the Sony label is different.  You can save some serious money this way by getting used gear that's functionally identical.

http://www.dyxum.com/lenses/detail.asp?IDLens=187 (http://www.dyxum.com/lenses/detail.asp?IDLens=187)
Getting back to the "missing a fast wide 24" comment, this is as good as it gets.  Discontinued, but well worth considering.  My old Minolta years ago had a similar 28mm/2.0 on it and it was my #1 lens that was on it all the time for trips and scenery.  I never noticed the difference anyways between 1.4 and 2.0 on any lens since the last stop isn't really usable anyways (though other will give you clean images at 2.8, which is far better than having a 28/2.8 that's only sharp at f8 or so)

You have to make a *few* concessions with Sony these days, but that's true for every lineup as well.  Each has their small holes and lenses that you wish were offered or done a bit better.

Here's a quick Sony Lens follow-up question.  As I've said before, I've got the Konica Minolta 85mm f/1.4 and a Konica Minolta 24-105 f/3.5.  I don't know if these are full-frame lenses.  If I were to buy the Alpha 850 or 900 would I need to crop?  I'm not sure how this really works.

I don't either, but they almost certainly are because 24mm is not very wide for APS-C and 85/1.4 is a classic portrait focal length for 35mm full frame.

There is an APS-C crop mode that can be activated; unfortunately there is no mask of the viewfinder so you have to rely on the viewfinder guides to frame your shot, and there is less viewfinder magnification than what you get from a smaller format camera.  Sony is also deficient in not giving any RAW shooting benefits (that I'm aware of) to the APS-C crop format, most notably you're still stuck at 3 fps on the A850.

Nonetheless, at full frame the A850 is a really fine camera as far as image quality is concerned.  Its AF is snappy, and its individual pixels have more acutance than what I get from my D300 pixels.

Both of your lenses are FF lenses.....the 24-105 is actually a f/3.5-4.5 (introduced by Minolta in 1999 and the near identical Sony version with some coatings improvement, introduced in 2006).  Sony recently stopped production of the 24-105 f/3.5-4.5, and there is speculation that a new 24-105 f/4G SSM is on the way soon.

The A900 has a 100% viewfinder and does 5 fps.  There appear to be very minor differences in the spectral responses of the sensors, too small for most people to notice.

Post by: ErikKaffehr on December 30, 2009, 12:43:53 am
Hi,

Viewfinder is not 100% on the Alpha 850, I think it's 98%. So you get some more into the image than what you see in the finder. Only pro cameras have 100% finder.

Frame rate is lower on the Alpha 850 (3 FPS vs. 5 FPS).

Image quality wise they are supposed to be identical, at least according to DxOmark.

Best regards
Erik

It's a pity that Zeiss doesn't offer fixed wide and super wide Distagon lenses with the Sony attach. There is only the Vario-Sonnar T* 2.8/16-35 ZA with a weight of 900g. I would like to use the manual focus Distagon lenses on the Alpha 850. Otherwise I have to wait for the upcoming Canon 5D MK3.

Post by: ErikKaffehr on December 30, 2009, 03:20:43 am
Hi,

What's wrong with the existing Canon 5DII ?!

Regarding lenses it's well possible that Sony comes with some more Zeiss lenses. The 16-35 ZA is said to be pretty good. I have an old Minolta 20/2.8 AF lens and it's pretty good if I stop down.

It is my understanding that some of the Zeiss lenses are star performers, but with manual focus lenses we would really need "live view". Using a lot of fixed focus lenses and switch all the time is a good recipe for dust and dirt on the sensor.
 

Best regards
Erik

A person in Europe, linked to the pre-release field testing of Sony lenses (also a top-notch photographer), indicated that there are around 8-10 Sony lenses on the way in 2010, including  Zeiss primes and also a 500mm f/4G SSM.  About the 500mm, his initial indication was that it would be an f/4.5 but he later confirmed that it would be an f/4.

PS:  In all of the prior Sony releases, he has been dead accurate with his predictions.  One of the possibilities for 2010, is a CZ 18mm.

Scroll down to the Minolta 35/1.4G and 35/2.0.  Again, same lens just not currently produced by Sony with their name on it.

35mm is a favorite of mine as well for photographing people and scenery.

http://www.dyxum.com/lenses/detail.asp?IDLens=14 (http://www.dyxum.com/lenses/detail.asp?IDLens=14)
This has some images of it on an A900 - so it does quite well with the new cameras as you can see.  I like how it looks identical other than the aperture's changing the field of focus(though 1.4 is a bit soft, 2.0 is perfect).  

http://www.dyxum.com/lenses/detail.asp?IDLens=13 (http://www.dyxum.com/lenses/detail.asp?IDLens=13)
I especially like the white cat.  It's exactly the same breed and color as mine that recently passed away(wish I had a photo of her like that...) - obviously get the newer model, though, as it's better and has more features - but the optics are identical.

http://www.dyxum.com/lenses/detail.asp?IDLens=70 (http://www.dyxum.com/lenses/detail.asp?IDLens=70)
Here's the 2.0 - IMO, I don't see a huge difference.  It's clean at 2.0 and appears to be essentially the 1.4 if you didn't have the last stop as an option.   For $300 or so, used, this is a steal.
http://www.dyxum.com/dforum/topic11527.html (http://www.dyxum.com/dforum/topic11527.html) - more images.  Again, the older lens here - same optics as the new.

http://www.dyxum.com/lenses/detail.asp?IDLens=2 (http://www.dyxum.com/lenses/detail.asp?IDLens=2)
Here's another one I hope to own some day.  I never have used a 50mm - the aspect ratio just looks "off" to me.  I like 28, 35, and 85 a bit more as options.  Three extra compact prime lenses also hardly take up any space.(my fourth is a nice macro zoom lens for when I absolutely have to have that type of shot.

Unfortunately the out of production 35f2 is very hard to find and usually very expensive due to demand.  If sony were to start production on it then it would be another story but I guess from your post the chances of a new 35f2 or 35f2.8 is zip. So basically it is the $1400 35f1.4 or zeiss 24-70. Obviously at that price point (and from tests) the zoom would be a no brainer; zept I rather have nice pocketable 35.

Yeah, finding these used can be a bit of a pain at times.  The zeiss zoom, though, is a very good lens.   One just sold on Ebay for $1200 used, which while expensive, probably replaces three lenses right there - the 28, 35, and 50mm.

Hi,

The Konica-Minolta 28-75/2.8 is an economical alternative. It's really a Tamron lens, one of their better ones. Sony has released it again under the Sony name, with built AF motor (non SSM).

Yeah, finding these used can be a bit of a pain at times.  The zeiss zoom, though, is a very good lens.   One just sold on Ebay for $1200 used, which while expensive, probably replaces three lenses right there - the 28, 35, and 50mm.

I've played around with both and it's not even close to the Zeiss.

The problem is that like most zooms, the last stop is essentially there for looks.  4.0 is where it is somewhat sharp again, and if the goal is to be able to use the full range to replace primes, it's just not any better in real use than a typical budget zoom(ie - nice for a trip but not for real work)

The Zeiss, otoh, is a fantastic lens that is usable at 2.8 throughout its entire range, which almost makes it a replacement for a set of primes(all but the most picky wouldn't likely notice since most primes have to be used at 2.8 to get sharp again).

While I suppose the Zeiss is much better, I'm quite surprised on the sharpness of my Tamron 28-75/2.8 at 2.8.  I do know there's a big sample variation.  I did compare to a sample of the KM 28-75 and that one was not sharp at all at f2.8.

Well, I have both.

My sample of the Konica-Minolta 28-75/2.8 clearly outperforms the 24-70/2.8 ZA when shooting test targets at close but I'm satisfied with the 24-70/2.8 under field conditions, essentially longer distance. I'm using the 24-70/2.8 ZA mostly, but it may have to do with placebo effect.

I made some comparison the first day the 24-70/2.8 ZA arrived

Klick on "original" size to get full image.

The 24-70/2.8 is built like a tank (although having some play in the lens barrel) the Konica-Minolta is more like "adequate".

By the way, all my old test images are here: http://www.pbase.com/ekr/a900_test (http://www.pbase.com/ekr/a900_test)
