My publisher, Rocky Nook, has given me a contract to write a volume on both cameras. My wife, Carol, and I have previously written books on the Sony A77, the Sony NEX-7, and the Sony NEX-6. For the next two months, we will be taking pictures with both cameras to learn of their strengths and weaknesses. Because of the paucity of full frame NEX lenses, we are checking the usability of camera adapters and legacy lenses.
Both cameras, as would be expected, work well with the LAEA-4 adapter. Also we are using some of our NEX-6, and NEX-7 lenses on these full frame cameras to check how well they handle the APS-C lenses. As a side note, we found that the LAEA-4 adapter focuses the Minolta AF 500 mm f8.0 Mirror lens and the 90 mm Tamron f2.8 Macro. I just spent the day shooting a 20 mm f2.8 Nikon and the results look pretty good. It takes a little practice, but one can manually focus this lens quickly with the aid of the Sony's focusing aids.
