I am leaving on a three week vacation to europe in a about six weeks. My current kit consists of a 7D, Canon 15-85, Canon 10-22, and Canon 70-300.
I obviously use the 15-85 as a walkaround lens. I am very happy with the lens, and even though I don't often use the upper end of the focal length range, it is nice having it there.
But....I am contemplating moving to the 17-55 2.8. Constant aperature and better low light, etc.
I am sure there are other similar threads out there....but
I am interested in opinions about making this move. Thanks !
