I have recently tested the M10. ( beautiful camera) I found that compared to the M240/M262 I really struggled to see and line up the RF patch.
I found that the brighter OVF in the M10 to make it difficult to see, especially outdoors. When lining up on a darker contrast there was no problem but in a lighter contrast situation I was just having to make a guess which was resulting in out of focus images.
From what I have read, a majority of people are saying the opposite, and
I’d be interested if anyone else is having these issues, and if there is a way around my findings.
