Just got my new E-PL1 a week or so ago and have finished first round of lens tests. Thought I'd share, though some of what I'm reporting is found in bits and pieces around the web.
I used Chinese adapters for both lenses - M adapter for 40mm and LTM adapter for the 25mm (the older non-cammed LTM version of the Skopar). Both adapters focussed to infinity, but each needed to be shimmed to correct the incredibly TOO thin adapter specs.
These tests shot on a tripod, with IS off. I'm not a testing freak, as I shoot MF and LF when sharpness matters, but I like to set a base understanding of all new gear, so I know what its strengths and weaknsses are, and then I just go out and use the stuff, never shooting another test chart or brick wall again!
40mm Summicron: sharp all the way across the image. Soft and desaturated at f/2, as this lens always has been, but when used on a m4/3 body as an 80mm equivalent, this actually makes a very nice portrait lens! Sharpens up a lot by f/2.8, but very sharp at f/4 through f/8. f/11 slightly less sharp, but f/16 understandably soft.
25mm Skopar: centre is sharp at f/8 and f/11, with f/5.6 and f/16 being only slightly less sharp. f/4 and f/22 too fuzzy to use to suit my tastes. The corners, however, are quite soft on this lens on m4/3. I was hoping this would not be the case, but it clearly is. The central 50% of the image is fine, but then is starts to taper off, with the very corners amazingly smeared. That said, I will still have no problem using this lens for street photography and general snaps, as it's sharp in the centre and has great contrast and colour rendition.
BTW, I love the ergonomics on the E-PL1. Very similar to using my Leica CL.
