Rear element protrusions? Surely it's only the prong provided to protect the
rear element of those lenses which do not have a recessed rear element. A
similar problem to that which afflicted some of the same lenses fitted to
EOS and Fourthirds adapters with a focus confirmation chip. Bring out the
Dremel!

Harumph, harumph. The SB for MFT is especially designed to be
optimized for the smaller sensor
and the approx .71 X FL change will be about the same. Seems they
didn't realize how many rear element protrusions might interfere.
Perhaps the MFT version won't have as many limitations to use Zuikos.
Normal speed, Mike
