I thought I would try the Sony NEX7 with every lens I had.
I'm not drawing any conclusions, just posting the images for you to enjoy.
The camera was the latest pre-production version which I just picked up this week.
The ISO was set to 100.
Camera on a man's size tripod.
Self-timer so I didn't jerk anything.
Everything was done on manual focus... used the scene enlarger to focus the best I could.
This is the Zeiss M-mount 25mm ZM at f2.8.
