I have a Zuiko 50/1.4 with slower than normal aperature blades.
They aren't "snappy" like my 50/1.8, but they aren't "creeping"
either.
When I press the dof button and release it, the blades quickly
close, but not nearly as quickly as my 1.8.
Is this ok? Is there a possiblity of underexposure from the blades
being ever so much slower to close & open back up? It seems like it
only takes a little bit more pressure on the 1.4 dof button to close
them as compared to the 1.8.
thanks
Corey
Absolutely. I ruined rolls of pictures in China with such a problem.
You can easily check with some sequential pictures of the same
subject alternating the lenses. For peace of mind a clean and lube
by your friendly service guy will take care of it. Don't wait until
it ruins pictures that cannot be repeated. John did mine.
