I'd like to solicit thoughts and opinions about how to use a 100L at less than 1 foot distance  or perhaps same working distance but greater magnification.
My guess is a diopter on front or extension tube on back or maybe both?
Please chime in if you have a solution and can comment about the pros and cons!
LOL, maybe the right answer is MP65 but not ready to go there just yet...
