What is a good magnification to start with for focusing 4 x 5 GG?

It depends on the granularity of the ground glass, but something in the 3x to 7x range should suffice.

Thanks. The old 50mm f/2.8 enlarger lens works nicely, but it really is too nice of a lens to use unprotected in the field (and I use it for APS-C macro, anyway). Loupes are cushioned at both ends, and the glass is set in a bit so less prone to scratching.
Keep in mind, it doesn't mater what diopter, they are all designed to be used at appx 14 in.Originally Posted by Ari
I have trouble with loupes, I remove my strong progressive glasses and stick my left eye about 2 inches off the GG and achieve MY best focus that way.
I think everybody's eyes are so different, each must find what works for them. There is no single solution.
