I have a 30D and two lenses, EF-S 17-55 2.8 and EF 70-300 4-5.6. Last week I ran into a situation neither could handle.
I was at my son's orchestra concert in the middle school gym. The 2.8 was fine with that lighting but 55mm was just too short to get good shots and the 70-300 was just not fast enough. So one lens had the aperture but not the reach and the other lens had the reach but not the aperture.
I'm not interested in a 70-200 f2.8 right now, in adequate light I've been very impressed with the IQ and performance of the 70-300, I don't really want another lens for the outdoor situations it can handle.
But for the times when I need a wider aperture and more reach I'm thinking of the 100mm f2.0 or the 135mm f2.0. The 100 has a great price, the 135 has rave reviews and a price approaching a 70-200 f2.8 zoom.
Any opinions? Under the given conditions would you be satisfied with a 100 prime or is the 135 just too good, in spite of the price?
Of course I'm using my current zoom at 100 and 135 to test the lengths. I'm just curious if any one out there has had the same situation and what they decided to do.
