Experiment with A7r and low cost Minolta 75-300mm AF F/4.5-5.6 zoom. To begin with, this lens needs the Sony LA-EA4 Nex adapter to work as designed on the A7r. The problem is that the adapter cost four times more than the lens. This is OK if you have a heavy crate full of Minolta AF lenses but pricey for one or two lenses. The first thing I tried was to use a cheap ebay adapter without any electronic coupling whatever. This did not work due to internal flare and vignetting on top of that. I had also tried an LA-EA2 adapter which did pass through EXIF data and allow shutter speed selection but would not do full frame correctly even when I removed the internal cropped sensor black plastic baffle and turned off the auto sensor. I was again rewarded with vignetting just like the cheap ebay adapter, but now with EXIF data. I guess it is nice to know the A7r does correctly spot the LA-EA2 adapter as a cropped device. Finally, I decided to use the adapter the way it was designed. I had read in a lens review that the Minolta 75-300mm AF F/4.5-5.6 zoom was at its best at F11 and 200mm into the 300mm zoom range. Final solution, use the cropped mode, set the lens to F/11 at 200mm and get a smaller image file that effectively looks like 300mm on a full frame. Here are the results in bright high contrast direct sunlight.

actually, they're yelling at some tourists for parking to close to them. a couple seconds later they surrendered their bench when the tourists got out of the car:
this actually a two image stitch by the way. the right hand side is at f/2.8 and the left is at f/2.
