I recently took delivery of a Pentax 40 XL. I hadn't previously
realized that the eyecone for the 40 doesn't adjust like the others,
with the full eye relief obtained by removing the standard stationary
cone and replacing it with a lens-flush guard. Since the top lens cap
is fitted for the cone only, what do you eyeglass wearing XL40 users
use for a cap? I'm currently using a plastic sandwich bag to protect
it from dust/dew, but there has to be a better alternative.
