I doubt it it a dome at all. Probably flat port.
The problem with the oly lenses on the gf1, is that they double, or worse, the focus lag time, from .2 to .4 seconds.
Guess an entry level slr is still the way to go.
Until another lens is out in the 1 year old micro four thirds market...
OK, let me rephrase that. The Oly 7-14 for 4/3s and the Pany 7-14 for Micro4/3s have the same close focusing distance (0.25M). They are not the same lens. The Pany lens is designed for the new mount and the focusing of the G1, GH1, & GF1 has been reviewed as fast. I see no reason this lens can not be used in a w/a dome port. I was just wondering how the Oly users set up their 7-14 in the Oly or another band of w/a dome.
