No matter what film/sensor size it's designed to cover, f-stop is a
physical ratio. 300mm/2.8 = 107mm. Add something to hold the glass and
the minimum filter thread is about 112mm. However, in terms of field of
view, it is equivalent to a 600mm/2.8, a beast we are unlikely to see
for 35mm/

A lens of equivalent, not equal, focal length would be notably
smaller. Compare that 4/3 300 against a 600 for the OM. There's your
savings per relative perspective.

The filter size of the new Olympus 300/2.8 is 112mm so it is the
same size as the Tamron and Tokina 300/2.8's and appears to have
the same body size. I don't see any size saving at all.
I was hoping for something smaller. Hope it is light though!
