off-topic reply because I'm not talking about the oly mount version...

Hmm, that's interesting. Just a bit wider than 'normal' on an APS sensor
(maybe longer than 50mm eq. on an Oly?) and at 1.4! $450

The Nikkon 35mm f/2 isn't all that great so this may be worth looking at
& the 28mm f/1.4 is like $1,800 which is just silly for what used to be
a $100 f/1.8 normal prime.

These are lenses made for a 1.5x or 1.6x sensor, correct?
They should work well with the 2x sensors since only the
central portion of the light cone will be used.

No, only some of them. The rest are full frame. It's easy to
check the spec without having to guess.

Only the Sigma "DC" lenses are made for a 1.5, 1.6, 1.7 sensor.
