I should have paid more attention; I ordered and waited three weeks for an Oly 12-50mm lens (I have the adapter) for my EP-2. I did this without ever seeing the lens in person. I got the lens yesterday...it's on the way back to Adorama today. Huge lump of metal on the camera, which might have been livable. The lens won't focus on the EP-2 except in AUTO and even that is marginal. I have seen the tables that list what Panasonic and Olympus lenses work with which cameras but just didn't grasp that would be an issue with this combination. I have a bunch of OM legacy lenses that work swell with an adapter, but no other autofocus except the kit lens. Drat!
Only native MFT lenses are the ones specifically built for the MFT format. 4/3 lenses will fit using the adapter, but it doesn't mean they're native to the MFT format. You'll also run into the AF issues you've already experienced (i.e. you're better off manually focusing those lenses anyway).
This is a little off topic (maybe) but some thinks the rebadged CCTV Noktor is a native lens... In the lens review section 4/3 lenses are placed together with µ4/3 lenses while the Noktor hopefully will be sorted among adapted lenses. Nitpicking, I know. I agree about µ4/3 lenses being the only native ones and I think 4/3 and µ4/3 lenses can be sorted as they are in the review section. OK, I'll now go back to normal, a tad less grumpy, mode. Jonas
Agreed the 12-60 is a big lens for such a little camera - though it is a superb lens - i use it on my Olympus 510. I haven't tried it on my e-p1 as I dont have the adapter - but maybe something to check is that the lens and camera firmware is uptodate. You have to user the olympus software to do this cheers K
I had the 12-60 in my 4/3 kit and its performance on the E-P2 was so disappointing I sold all my 4/3 gear.
Pretty simple to answer: NATIVE m4/3 are: labeled as micro 4/3 and made by Pansonic/Leica and Olympus. Anything else will need and adapter (ex. regular 4/3) or will have limited functionality via the adapter (ex. old Leica lenses, old Olympus OM and Pen lenses, Canon, Nikon, etc.). Nothing mysterious here at all. Just like Olympus Zuiko Digital lenses are native to Olympus DSLR's. Anything else is non-native.
