I am looking to replace my 18-55 is kit lens. I currently have the a 10-22, the kit lens, a 100mm macro, and a 70-200. The lenses I am considering are the canon 17-55, the tamron 17-50, and the canon 28-135. I'm leaning towards the tamron or the 28-135 to save money but am not sure how much I am sacrificing by not going with the 17-55. Part of me also feels like I am upgrading for the sake of upgrading. I feel a need to upgrade because of the stigma surrounding a "kit" lens. Anyway, any thoughts would be appreciated. Thanks.
