The Olympus 17mm f/2.8 is a compact pancake prime for Micro Four Thirds, providing a 34mm equivalent field of view — close to the classic 35mm perspective beloved by street and documentary photographers. Its slim profile makes it the ideal pairing with compact M4/3 bodies like the E-P1, creating a very pocketable combination. A useful everyday prime for candid and street shooting where discretion and portability matter.

Great little lens - maybe a tad slow on focus.
