Sony A7R first impressions

My Sony A7R has arrived and so did the Metabones adapter, so I have made my first tests with a combination of the Sony A7R and the Canon EF 16-35mm f/2.8L II lens. These are just some first impressions, but I have to say that I’m pleasantly surprised. The combination is sturdy and even the autofocus works (although very slowly)! I wouldn’t want to try to follow a moving subject, but the AF is adequate for landscape shots. Image quality is very good indeed, especially in the middle of the zoom range. At 24mm the image is very sharp and even the corners are fine (only tested at f/11, which I woud use for landscapes anyway). At 16mm (and at 35mm) the corners are softer, but the softness is not so severe that it becomes are real problem. Color fringing is a problem when you shoot in JPEG, but when you shoot in RAW and develop the images in Apple Aperture or Adobe Lightroom, that is fairly easy to correct. Apple released a Camera RAW update yesterday, so now Aperture supports Sony A7R RAW files as well. As could be expected, Lightroom doesn’t recognize the lens right away. If I want to apply lens corrections using lens profiles, I have to manually select ‘Canon’ as brand. As soon as I do that, Lightroom knows which lens it is, so this is also just a minor inconvenience. I’ll test the combination with the Canon 24mm TiltShift lens next month, that should really be interesting.
