Macro is a little different from other genres in that it has its very own set of purely technical challenges. Bellows compensation, (lack of) depth of field, reversing (or not) lenses, adapting other lenses for camera use - it's almost as bad as LF photography!

Many of the difficulties are common to LF and macro, but I won't expect a 35mm macro shooter to learn LF photography, nor read the LF specific discussions.

That's why I'm in favor of a macro forum.
