Hello, I posted about 2 months ago, asking about what lens to buy as a general purpose (mostly landscape) lens for my Canon Rebel with a broken kit lens. I got a lot of advice and appreciate it. I went to various camera shops here in Toronto and was very disappointed by the help I didn't receive so went home. Ventured out again today with some more info. I have access as well to 2 full-body camera bodies (lingo may not be right) as well as my Rebel, so I would like a lens I can use on both cropped and full-body cameras. I didn't actually realize that lenses weren't always compatible with both... Now I am looking for recommendations for a 17-50'ish lens for now. Will add on with others later. Also, would anyone know anything about the L24-105 IS which is new in terms of whether it is good...thanks again.
