Trying out my Luminar 63mm (version 1) for the first time. The flower was not ideal. I would normally use the lens on longer extension for higher magnification.
Olympus EM-1, 100mm extension, Luminar 63mm first 3 at f9 ("2") then 2 at f13 ("8") FOV 11mm, ISO 200, twin flash, hand held (resting on table top).
This flower has the problematic blue color.
The images are uncropped, except by the stereo maker software.
Single frames are posted with macro images.
First one at f9 then one at f13.
