I keep posting that thing because new E-1 users and wannabies keep
asking what the deal is with OM mount Zuikos and others on the E-1. I
think a picture is worth quite a few words. I know the E-1 does this
different than the 300D, but it at least gives a clue of what the issue
actually is.
And I keep hoping one of those E-1 enablers will do something similar
for their buddies. Hint, hint.
Could even be a group project to cover many of the more popular lenses.
Or perhaps it would prove that all the trouble is just above a certain
f-stop, regardless of lens and fl? I would participate if anybody wants
to send along an E-1 and MA-1. I'll send it back as soon as I'm finished
playing. :-)
Seems like something the old list would jump at, an opportunity to
document something both Oly and really useful to Oly users.
