I'm trying to figure out my next lens for my e-p1. I'm looking at the Olympus 40-150mm - I think I need an adapter - would the adapter be the mmf-1?  Is there an adapter for Nikon-to-ep1?  Thanks for the info.

Yes it would. Four Thirds to Micro Four Thirds. If you also want to buy a cheaper version, Panasonic has one available, and it also allows autofocus. It's just...oddly colored.

Olympus 11-22, generally with the evf on the E-P2.

Its a handful, I'm pretty sure the lens and adapter weigh more than the body, but it makes nice images.

tamoio, I've heard lots of recommendations for that lens too. I guess it's a cracking good lens after all!

You actually need to be a little careful with it, it doesn't AF very well and a lot of the time I just stop down to 5.6 and infinity MF. But it feels like a real lens to me, unlike the the new 9-18. It also works really really well on an E-3.

Can you post samples in the Lens Sample board? I don't think we have samples with this lens yet.

I'm trying.

I own four Lumix lenses for my Lumix G2. Of these the 45-200 is the one that stays on the camera most of the time. If I had to choose a second it would be the f1.7 20mm pancake.
