I am shooting 4x5 and recently got a 90mm lens. I quickly found out that to focus the lens at ANY focal length with a flat lens board I had to have both standards on the same side of the center block.
Is it normal for a 90mm to only have about 1/2" of usable focusing adjustment???
If I got a recessed lens board would the usable focal distance get longer?
I may not even be asking the right question but this is where I will start.
