Advance Coverage on Four Thirds and Micro Four Thirds Lenses
In addition to my review of the Olympus OM-D E-M5, I now have posted some advance coverage of a number of Olympus and Panasonic lenses for the Four Thirds and Micro Four Thirds standard.
The coverage includes a size comparison between lenses for DSLRs vs Four Thirds, and a discussion of depth of field and a discussion of focal length.
See my gear page for Olympus and Panasonic Four Thirds lenses.
