Olympus 12-40mm f/2.8 Zoom

I spent an entire day today shooting the Olympus E-M1, focusing on the new 12-40mm f/2.8 zoom with many comparisons and some ad-hoc shooting also.

Optical performance is both an absolute and a relative thing in the context of size/weight/cost of alternatives, so I made comparisons with the Panasonic Leica 25mm f/1.4 and Panasonic 20mm f/1.7 as well as the reference-grade Olympus Super High Grade (SHG) 7-14mm f/4 and 14-35mm f/2—those two SHG lenses setting the unrivalled benchmark for Micro Four Thirds sharpness, though autofocus performance is dismal.

While the E-M1 is very enjoyable to shoot for ad-hoc stuff, it takes real discipline to shoot Micro Four Thirds on landscape, with alternatives like the Sigma DP Merrills, Leica M240 and Nikon D800E all outclassing it on sharpness, and all with me on this trip. But the day was well spent and now I have a good pool of material to draw on for the E-M1 and the 12-40mm and those other lenses (comparisons).
