Well after a week with the 100L, I felt like I was forcing myself to use it. So after much consideration, I exchanged it for a 50L. I've only spent 2 1/2 days with the 50L, and this was what I wanted. Certainly seems excessive to have 35/50/85/135, but that's how I shoot apparently. I did get some very cool shots with the 100L, but after a few days I was just finding that it wasn't really my thing. Luckily I have a Best Buy near my office that seems to be a pilot store for a larger photography area and they stock a number of lenses not normally seen at Best Buy.
