I am adding a "walkaround" lens to my kit for mostly my wife's use on her XT... I want it to be a lens that she can destroy, and i don't care about it - she will probably wreck it in one way or another.
Can anyone tell me where the sigma's max aperture goes to f/4? Is it only f/2.8 at the 17mm length, or does it have 2.8 until maybe 50mm?
Does anyone have any real strong advice as to which is much better or worse than the other? At this point I am really just tempted to get the sigma, for the focal length, although if the tamron is very high quality/IQ... that is the one i'll get.
Any help is appreciated. FM doesn't have many reviews on either of these
