Hi Charlie,
The first image with the CV21 and the A7M could be improved using Corner Fix, but you would need some references for the correction.

Hi Rich,
I used corner fix a bit, then Adobe Flat Field Correction plugin, which is a bit easier. You make your own lens profiles. It does work, but the whole image WB seems to effected and editing it's like you shot it on some other camera. I did not like it, and I never do it, but somebody with more patience could I'm sure.
I just never use the CV 21 on the A7.mod This was quite a difference in the A7 and A7r, the latter does shift color on many more lenses. I thought that was the smaller pixel size. You don't see it so much the r2, which is impressive, and of course it's a totally new sensor.
What I recently learned about the A7r, is that it is better at high ISO than A7, at least by the numbers, even better than A7r2, which is sort of a shock to me: I never tried the camera at 6400. Kasson measured it though. A7 is not great for ISO. Better than M9, but only by a small amount.
Perhaps my problem with A7r was not watching the noise improvement which comes with reduction. A7r2 looks quite noisy at 100%. But those file get clean at M9 size. Also something new to me. 
Looking back at my test shots, very few A7r were at high ISO, but here is 3200:

Actually looks great, better than A7, for sure, but on the full
You see some real noise
You ever try high ISO, Rich?
I think this is basically on topic, because the M10 ISO performance in a BIG deal. But when we compare to r2, we need to have the files the same size, in pixels, to be fair. And maybe the A7r has got short shrift on it's ISO....from me for sure.
I was so beside myself with the smearing and colorshift...I missed that. Looking at other ISO 2000 and 1600 shots, A7r looks very good. All these Sony problems with RF lenses were a godsend though, because it forced the unthinkable: M9. The final straw was at 28mm. I was testing A7 with elmarit v3 28, and thinking, well maybe this is OK:

So I posted at RFF, basically asking: beat this with Leica M. Some nice guy took pity and referenced a M9 with 28 cron full size. Game over, no contest. I realized there was no way I could get a small 28 working on the A7 cameras. No mod at the time. I found a M9 for sale within a few days, and just ate the expense. Family was horrified:
You bought a Leica? by unoh7, A7 + CV 35/1.4

To this day A7x options at 28 are meagre 
So my purchase had nothing to do with RF. I was still convinced at the time EVF was better. That did not change for at least a month. The farming was so foreign I missed the obvious clarity and accuracy. 
I should thank Sony, but I'm still mad at them for misleading marketing. No one can say I did give those first cameras the benefit of the doubt, though. I defended them tooth and nail until there was just no doubt they had made some weird choices.
M10 introduction is going very smoothly compared to M8, M9, M240, and A7, but's elary days
A very few are appalled by lack of video, and even the obvious fail on weight is not considered a big deal at all. Ming won't even talk about the camera, but I don't see many others with bad feelings. Huff is Crazy about it, which is hilarious, after he was such a "Leica is yesterday, Sony is now" guy. I admired his adoption of SL. His sony fans were appalled. Even DPR is gaga.....and that is totally unbelievable.
They never made a full review of the M9 at all.
