Been thinking about getting a loupe for the GG, as my eyes are, for sure, not getting any younger. What I'm doing now is using a pair of 4x reading glasses and it's working fairly well for the images I'm making. My reading and research shows folks' opinions and recommendations about loupes are all over the board.

One thing I've seen more than a few times, though, is that the 'proper' way to employ one that is adjustable is to remove the camera lens, use the loupe to look thru the GG at a light source and, when one can see the 'grains' of the GG, to lock the loupe at that point. My question is this: is there an empirical/visible difference between an image made this way and one made by not doing it this way? Isn't it kinda splitting hairs? Just asking questions here.
