9 out of 10 points and recommendedExcellent Sharpness with f/6.3 --> f/11Little soft wide open
I wanted to compare this with the ED L lens that came with my E-PL1 but I found it much softer!! Fortunately I had read the previous review posted by Bruce Coxley. I did what he had done, i.e., reset the lens and it changed the whole thing!reviewed September 1st, 2011 (purchased for $213)
I found the lens excellent in sharpness, beating the 1st gen. ED L lens with aperture f/6.3 --> f/11 at all focal lengths I tested (14, 18, 24, 35, 42mm). At 24mm with f/6.3 and 35mm with f/6.3 and f/7.1 the ED L lens was sharper--but only in the corners.
This lens shines over the previous version especially with apertures f/7.1, f/8, f/9, and f/11.
The quality of the build is much better than that of the ED L. I also took few videos with it and found it whisper quiet when zooming--great for video!
Autofocus on E-PL1 also seems to be faster. I'll do some tests later to measure the different.
Overall a great lens!
