Re: Fun with the A7/7R
Marke Gilbert is a Canon guy and had a Canon lens with him using a Metabones AF adapter. It was pretty slow focusing (as in "snail slow") ... okay for more leisurely, static subject work.
In contrast, the Sony LAEA4 Translucent Mirror adapter for my A mount lenses was at least as fast AF as my A99. I did not have the camera in hand long enough to properly test it on a moving subject.
I need more time with this LAEA4 adapter and the ZA lenses ... the few shots I did with a ZA24/2 were not in critical focus, but I didn't concentrate on that aspect or how to set the AF array, and so on. The ZA50/1.4 was better. As was the ZA16-35/2.8, and at 16mm seemed about the same as on the A99 with some similar levels of vignetting expected @ 16mm.
If I go for A7R, I'll probably get a few native lenses for it ... but for the most part I view it as a back-up to the A99 for paying work using the ZA lenses I already have ... and a small high res color portrait companion to the Leica M Monochrome when traveling so I don't have to drag along a different set of lenses. I do not use WA lenses very much even on the M camera.
So, I was far more interested in how it worked with my M50/0.95 and 75/2AA ... plus tried it with the M90/2.8. Focus peaking seems to work very well on this camera. The most interesting aspect was how fast and easy it was to focus @ 0.95 in lighting conditions that would be very challenging for rangefinder work. The A7R's EVF is literally like adding night vision.
For me, the singular most important test of this camera is for use with the M50/0.95 (my most used focal length by a huge margin) ... it has to only work with that lens to make it worth the price.
I have a Leica M240 Demo coming tomorrow AM to test and write a review ... I am going to try to get Marke to bring back the A7R so I can do a few comparisons based on how I shoot.
