Eye relief. Should I always extend it when not using glasses?
It's daft but I cannot tell what is best. I know if I have it fully screwed in, I have to hold the binoculars away from my eyes to avoid vignettes.
But if I fully extend it (screwed out) while I can see without vignetting, it feels like the circular field or view is reduced? Is this possible or am I imaging it?
I feel like at this stage I should just wind them in and hold them far away from my face as it's easier to adjust, but I don't know if that's the proper solution or not.
