I'm interested in your thoughts on this quartet of Canon lenses for use on an XS camera. I personally feel that it covers most bases; with the expenses being within the necessary boundaries--under $800(total) in a good used market. The 4 are: 18-55IS, 50 1.8, 28-105 3.5/4.5 USM, 70-300IS USM. My photo needs are pretty universal. But to put them in some sort of priority, here goes. Nature/wildlife, grandkids sports(in and out), travel, walkaround, landscape, etc. Goal is always 8X10 prints. So, staying within the total value of the this group of lenses, in other words $800 max, would you advise any rearranging or substituting anywhere? I guess I really want to know if I'm overlooking anything obvious here. And, I wouldn't need 4 lenses if 3 or even a mere 2 lenses would cover my needs(withing my dollar figure). O, I do have a very able S5IS, also. Thanks for your comments.
