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 Sony Alpha 70-400G at f8 at 70mm.
