Currently I have Canon 500D with following lenses.
- Canon 18-55 IS.
- Canon 55-250 IS.
- Canon 50 1.8.
- Tokina 100 2.8 Macro.
These days I'm thinking of adding another lens to my armory. And my choices are as follows.
- Canon 15-85 IS. ( for its range )
- Canon 10-22. ( for its UWA capabilities )
- Tamron 17-50. ( for its fastness )
Even after reading large number of forum entries and reviews, I still can't make up my mind on one lens. Basically I have trouble with 18-55 and I am pretty satisfied with other 3 lenses. My problems with it includes not sharp enough, not fast enough and not wide enough at times. But when I analysed pictures I have taken using exposureplot, I got to know that I am shooting in either wide end or tele end most of the time. Therefore 15-85 seems logical choice as it extends range in both ends. But strictly speaking in lens speed terms it wouldn't give me a much of speed performance over current setup.
Other option I'm thinking about is go for a 10-22 and extend my range in wide range and use 10-22+55-250 setup. But it will involve constant lens swapping.
Final option is to go for Tamron 17-50 non VC and possibly drop 18-55 and 50 1.8 from current setup. It's the cheapest option, will provide sharp pics, but current range restriction will be there.
I will really appreciate if you guys can provide me with some advice as it will make my decision process an easy one.
