Last night I set up on a sturdy tripod and took a shot of the moon. I was using a Sony a7r3 with a Sony 100-400 GM lens with the Sony 2x converter. I turned the steady shot assistance off and used a delayed trigger (2 seconds). My settings were M, ISO 100, 1/250, F10. I did my best in the manual focus, but either there is vibration I did not avoid or I did not focus well. Any suggestions?
I have had a good result focusing on infinity and than pulling back a nat's whisker. You can but try!
