Hello everybody, Right now i have a Canon T1i, canon 18-55mm, canon 55-250 and a 50mm 1.8 I dont like changing lenses when im outside and would much rather just have one lens, so im undecided between buying the canon 18-200mm lens for my T1i or just buying the 7D kit that will come with the 28-135mm. The 18-200mm lens would give alot of flexibility but i have read some bad things about it such as the vignetting and the barrel distortion on the wide end. Other than that it sounds very nice. The 7D will be a much faster camera and the focus will be better than the T1i, but im not sure my pictures will actually look noticeably better. The 7D will also cost about $1000 more than the lens. So what do you guys think i should do?
