So, I recently picked up this little 36 MegaPixel toy from Sony. I call it a toy because I just can't get over it's minuscule size. I've been testing it very casually, just going out and shooting and seeing what I get. Nothing very scientific. I'm using EOS mount lenses on it via the Metabones Smart Adapter III. It performs beautifully with the Canon Tilt / Shifts... allowing it to be what I wish the D800 had been (a high MP little camera with excellent T/S glass). The A7r actually has the same chip as the D800 (as I understand it) which Sony manufactures. Since it's mirrorless, it has a super short flange distance and you can adapt practically any lens to it, including Leica M glass.
Anyway, here are some shots from my living room:
Phase One IQ 260 / Arca Swiss Rm3d / Schneider Apo-Digitar 35mm/f5.6 XL *Processed in C1 Pro
Sony A7r / Canon 24mm TS-E II *Processed in LightRoom 5
Canon 5d2 / 24mm TS-E II *Processed in C1 Pro
Red Epic / Canon 17mm TS-E *Processed in RedCine-X
Right away I can see the difference in the C1P vs LR processing. C1P always seems to have snappier color to me whereas LR can usually dig out a little more Hilight info. I set the hilight recovery sliders at 30 in C1P and LR for all the still cameras. All three still cameras have comparable sharpness with the IQ back being a clear winner upon pixel peeping (no surprise). I turned off all in-software sharpening and the little cameras have neutral profiles in camera. I don't find the Red that useful for my stills work. It possesses much more shadow noise and much less sharpness than the still cameras but It's fun to see how it blows them away on DR. I think it was really designed to feel like Neg Stock.
You can download all the RAW files or my processed TIFFs via DropBox and draw your own conclusions: https://www.dropbox.com/sh/coeaopdb1srglbe/jdi7ZiT4IX
In conclusion... this was really all about evolving my own workflow and making life a little simpler and well... hell I'm a big gear nerd (but you knew that). Speaking of workflow, the only way I've found to shoot the Sony tethered is to use their Remote Camera Control software and setup LightRoom to auto import the files from a watched folder. Lame, but usable. C1P support is coming, they tell me.
