Quentin,

I have been following your work with the Merrills since the beginning, and still use mine. I've never bonded with the A7, and mine sits with 3 Zeiss lenses unused. Would you care to compare the A7RIi with the Merrill?


Thanks,
Norm


Hi Norm

Quite a task.  I never liked the A7R, and it sat unused for months.  The Merrill's are indisputably totally different and for mono work are in my view unsurpassed. The A7RII is a major step forward and their low contrast out of camera files are the exact opposite of the Merrills.

I'm still learning the A7RII so all I can say is - I will get back to you in a few weeks when I have done more tests.  I'm  not done with the Merrills....   ;)

Well, its a brick wall of sorts  ;D

Try photographing some building straight on, please, when you have the time.
In my opinion, your camera should be doing much much better than those crops.

Out of interest - in what way?

Don't forget that with a 42 MP camera you're looking at a very small piece of the sensor when enlarging to 1:1. Also this was taken with a zoom lens, a good one but still not a razor sharp prime like the FE 55/1.8. I also don't know if these shots were taken handheld or from a sturdy tripod (with proper precautions and AS off). A 42 MP FF sensor will be merciless for even a hint of camera shake, but by the time you sharpen and print they will most likely look very sharp.

Edmund, All

Respectfully, Edmund, I think you are confusing resolution with acutance.  The A7RII is a relatively low acutance camera. So subjectively, images that have not been sharpened significantly may appear less sharp.  Looking at the entire image on screen at 100%, the images look sharp and detailed  to me.  I have described these images as having a creamy texture.  You might see that as soft.  No doubt 42mp is pushing the resolution of most E mount lenses

Be that as it may,  I have uploaded a raw file of a building site taken on the A7RII, 16-35mm Sony / Zeiss lens, F/7.1, 1/50 sec, steady shot on, ISO 100. Click the link to download.

https://dl.dropboxusercontent.com/u/9806585/A7RII%20Test%20Files/DSC00009.ARW

Feel free to download, test, etc for sharpness or anything else.  I am entirely happy with the sharpness of images I have so far seen from this combo, but of course opinions can vary.  Given the distance of the building under construction, there should be no issue with inaccurate focus with this image.

PS I don't shoot brick walls!

Actually I should have mentioned the images that Edmund mentions - including my cropped samples -  have had quite a lot of perspective correction applied to them.  Apologies for not remembering that was the case.

You may be right, I am always a bit confused :)
I would assume that reality is somewhere between my pessimistic point of view, and Sony's PR :)
Thanks for the sample, I will see if I can find an app to open them with.

 Wow!! Color me envious, at the risk of asking a silly question. Is the lens you paired it with the sony lens?
 Thanks Quentin and best of luck with your new gear!!

i agree with edmund, not optimum in these cases, probably due to being hand held, but when the heavens align this thing is AMAZING! (with sony 55mm, minimum acr, no sharpening)

works great in the worst possible contrast situation:
(sony 55mm, processed acr: shadow & highlight recupereation, no sharpening)

I think that just about the highest rated lens on DxO Adrian, and yes, an excellent result.

also, honestly, if i have this camera through my dealer in madrid before steve huff and michael etc., then i think sony are pretty confident that they don't need a big PR push!!! the hype this thing is going to get will be no bluff!!!

Any one of you lucky bastards have a Leica M lens (preferably wide angle) that you can test on the A7R II?  I'm curious if it has the same issues that the A7R had?  Thanks!

Agreed.

I've just dug out my rarely used Zeiss 35mm F/2.8 ZA and tomorrow I take delivery of the very highly rated Sony G OSS 90mm Macro F/2.8.

It's prime time!

Quentin,

 I had a look at your shot of building with cranes; there is a lot of detail in the image, but it needs extreme sharpening to bring it out. As I'm not very smart, I don't know where the focus point is, and for a test shot it needs to be obvious. If you would shoot directly square against something instead of at an angle, just point the camera straight ahead of you at the building on the other side of the street, I could be sure what is going on. As it stands, there is nothing like the crispness from a digital back and MF lens.

Edmund

Edmund, I don't do test shots as such, just real world shots.  I also shoot with a Hassy H5D 200MS, so I am very aware of MF crispness.  Maybe our expectations are different, for the reasons I have previouly mentioned, and it will be interesting to see the difference between a high quality zoom and primes over the next few days, but honestly, I don't see the lack of crispness you are referring to, unless its simply the lower acutance I have mentioned before (although I would expect even better results with primes)
