I'm shooting a 40D and I have a 50 1.8, a 17-55, a 35-135 a 70-200 f/4 IS and a 70-300 IS USM plus a 1.4 extender. I'm getting antsy - I want a new lens but I can't figure out what to get. The 17 is wide enuf and with the extender so is the 70-300. I'm thinking of a 28-135 IS to replace the 35-135. I handhold exclusively so I like light lens with IS. Thots? Thanks, Harry
