Saw some pics of people using this 45mm with epl1.
Macro pics with this is terrific. Very sharp.
Really makes me a lil bit regret on buying the xz1.
I had to sell my xz-1 and housing because it would not TTL with my Sea and Sea strobes. I went to the E-pl2 which synchs fine with the strobes. The E-PL2 is a little larger, no longer "one handed" convenience, but, I am absolutely astounded at the improvement in image quality. It is amazing when you crop in. The xz-1 image "falls apart" very quickly (its sensor is only 1/8 the size, after all) where the E-pl2 stays very sharp. Also, MUCH better performance at ISO 400 or 800 if you wish (I usually never go over 400 because I am using strobes). Also, the colors are richer and the dynamic range much better. There is "only" a 20% difference in the megapixels, but, I would say, an 80% improvement in the image quality. It also shows in the video, which is much better than on the xz-1. I don't regret it for a second, and having lenses available like the Panny/Leica 45mm gives much better macro performance as well.
You pay only $50 more for an e-pl2 ($550) than the xz-1 (500 although I think they are now down to $450), but you do pay $200 more for the EP housing., (299 vs 500). But, for $300 difference, there was a surprising difference in the qualiy and I am happy I switched. It is a small amount compared to the total for the camera, housing, strobes, tray, arms, and video light.
The E-PL2 is, I would say, full-on professional magazine quality and good for prints even up to 20 x24". The xz-1 is probably the best compact camera out there, but the small sensor just cannot approach the quality.
