Since asking earlier about cheap M-to-MFT adapters, I thought I'd
report on my recent experience. Based on some earlier comments, I
ordered a couple from big_is. They actually work pretty well,
although the adapter-to-lens interface is much tighter than on my
Voigtlander adapter. It's actually easier to mount and unmount a lens
if you mount the adapter on a body first. The adapter-to-body
interface is much smoother. I might be concerned about lens mount
wear if I thought I would be mounting and unmounting frequently, which
shouldn't be the case since now I have 3.
I learned another difference playing around today. For some reason I
get great amusement from trying to mount just about every lens I own
onto a MFT body just to see how they handle and look (a Vivitar 600mm
Solid Cat is kind of a hoot). Today I thought I'd try the Dual Range
Summicron. It looks kind of silly in the close focus range, since you
have to have the goggles mounted, but works fine. However, I found
that you can't focus through the full normal range when using the
Voigtlander adapter because there is a kind of light baffle that
narrows the throat a little and blocks the focusing cam. However, the
big_is adapters have no such thing and so the lens focuses through the
full range.
I suppose there might be other M lenses that would have the same
problem, but none of mine have it except the DR Summicron.
