Nice to meet another islander! I'm originally from B.C myself (Vancouver Island) and immigrated to the states within the last 4 years to San Juan, so it wasn't too much of a move distance wise! I haven't had many opportunities to visit Lopez, but it really is a nice place.Hey, fellow islander! (I have relatives on Lopez that I have to go through Friday Harbour in order to visit.)
Have you tried using a reversing adapter?
In the film days, that was a cheap way of doing macro with standard 50mm lenses. The theory is that they are designed to be sharp with the back end of the lens fairly close to the film, so reversing them puts the back end about the same distance from the subject. (This "theory" sorta ignores that the objective end of the lens is still "looking at" the film at a fairly short distance, though.)
Thanks for the info regarding reverse adapters, it's one of those things that I've heard of but have never tried and didn't really understand how they worked in theory - definitely something to look into!
