Uh.....no. F2.8 is f2.8, as far as light gathering ability goes. Depth of field is different, yes. But 2.8 is 2.8 when it comes to exposure calculations, so I compare the 35-100 2.8 to anyone's 70-200 2.8. If I wanted to compare slow lenses, I'd compare the Panny 40-150, which is the closest to compare, until Pannys new 35-100 is released later this year. It's designed to compliment the GM1, and it's really, really tiny.

m4/3 lenses are smaller, of that there is no doubt.

Only correct in terms of ISO but ISO is based on sensor size. Please watch this YouTube video to understand this.


I do understand it. And what I said is true, according to the friendly guy in the video. f2.8 is f2.8. Yes, sensor size affects many things, but not the aperture.
