5dsr vs a7r vs a7rii

[Tim Parkin]

Well we can try and forget the first part here. Clearly if you set the cameras up side by side and take the pictures at the same time you end up with equivalent data. But I guess you didnt have the equipment.

On the second point - people wanting real world results I do agree. In point of fact the only reason I am arguing with you is because I 'genuinely' believe you are making 'false' claims about the 'real world' ability of the A7r2. Be clear, I have absolutely no agenda here. I own the camera, I love the camera but I seriously dont want people to believe its image quality is something it isnt. You can see I have pushed an exposure here 5 stops with exposures taken seconds apart - I have also posted the raw images.

If you go to the beginning of this thread you will see that people referred to your results as 'incredible' and 'amazing'. The reality is your results are 'incredible' only in terms of being 'unbelievable'. In reality the A7r2 offers a just noticeable incremental increase in image quality over the cameras that preceded it. I know it is an incredibly boring conclusion to come to but unfortunately there is nothing 'incredible' to show.

<sigh> You actually said "the A7rii performed better on the basis that it got over a stop more light than the others" which was incorrect.

If 7 minutes between shots and then compensating for the light difference makes my results invalid then so be it.

You didn't comment on the other tests that followed shortly afterward and even the image in the same article that shows that the cameras get a lot closer when post processed carefully. It's not my fault if the only image that people picked up on was the first 'straight out of lightroom' comparison. i.e. here's the fully post processed version.

What it shows is that the A7Rii does get better shadows straight out of lightroom - do your own side by side comparison and tell me different. . The studio test here shows the same thing. If you play around with the colour in the shadows with curves then you can correct the A7R to look about the same, if not slightly better after some more work.

If you want to ignore that then it's fine.. but the fact is that for the layperson who just uses simple exposure adjustments, the A7Rii will show better results. I think it's an interesting result.

Ok. Lets agree to disagree.

You think the difference between the cameras is interesting, I dont happen to think there is much difference. I very much doubt anyone else is reading this thread apart from you and me. And to be honest who can blame them?

We can certainly agree on one thing...

'If 7 minutes between shots and then compensating for the light difference makes my results invalid then so be it.'

"Ok. Lets agree to disagree."

This, please .

I think both of you have made your points very well for those who are interested in the analysis.
