I like the Olympus 4/3 14-54mm f/2.8-3.5 lens a lot.
- very useful range
- quite fast
- good optics
- not too big for m4/3 bodies
- a m4/3 version could be smaller
- IS only available with the E-P1/P2 sensor IS
- means no IS on the G1/GH1
I own a E-P1 but want an EVF. Just buying an E-P2 to use this lens seems a lot of money.
