I'm a newbie and just got my GF1, my very first interchangeable lens camera, just a week ago. Can someone recommend a sharp pancake lens in the 40mm - 60mm range? I've been going over the reviews of a few candidates - Konica 50mm 1.4, 1.7; Konica 52mm 1.8; Konica 57mm 1.4; Olympus 50mm 1.4, 1.8 - but was drowining in the sea of information. I have a couple of criteria: 1. Sharp image: I understand that some people prefer soft image when taking portraits, but I prefer sharp image at wide open. 2. Less than $80 Thanks!
