I didn't get a chance to shoot this beautiful lens until tonight just before dusk, when I took a walk around my property just catching objects here and there. Initial impressions from this lower-light time are pretty good considering I bumped up the ISO on a number of them. Some are at f/8 or so and others are at f/2.8. You can probably tell which are which. Shot with E-M5, captured as RAW images and processed in LightRoom4. The lens feels and looks very well made and substantial. It's somewhat larger than the Pany-Leica 25/1.4, but not significantly so. Lens surfaces are flawless and there is no apparent dust inside. And as with all Pany lenses, was supplied with a lens hood and protective bag. Nice touch, Pany! I have always been impressed with Pany lenses and this one definitely does not disappoint. Stuff grows here in Washington State.... like CRAZY.
