Crocus sieberi A7r3 with Printing-Nikkor 105mm at 1:1
These open only in full sun and these shots were grabbed during a brief gap in the clouds. 1/320 at ISO 800, probably all at f11. Hand held.
I have sometimes had a tiny bit of vignetting in the corners of the frames with this lens on the A7r & A7r3 but not this time.
Even e.g. at only ISO 800, one of the go to settings on my EM-1, the noise looks pretty ugly on both the A7r and the A7r3. As I always remove noise it doesn't show up in final JPEGs
The stereos are crosseye.
