Recently, I found a 21mm f4.0 in excellent condition. The store is asking for 2000usd (2 caps, metal hood, metal finder). Since I am looking for the f3.4 version so I didn't buy it. I have a few questions and would like to have anyone's opinions. Thanks. 1. Is 21mm f3.4 optical performance better than f4.0? 2. Is 21mm f4.0 more expensive than f3.4 because its SM and BM convertability? Tony Chang stchang@novice.uwaterloo.ca 4A Co-op Chemical Engineering University of Waterloo Ontario, CANADA
