I see prices going up here in Japan, too. Unfortunately non-film users are buying lots of lenses- specifically I've seen plenty of fantastic Contax and M42 lenses going to waste on little plastic non-film cameras.
Call me a fence-builder/snob/whatever, but I think they should stick to their crummy plastic kit lenses.
The current "trend" here is moving away from long-focus to wide angle. 90mm lenses aren't moving much, and 135mm can't be given away. More for me
