I had that same problem at first when I searched for a good replacement of my kit-lens [:P] As I was in a tight budget myself I bought the Tamron 17-50 and I was very pleased with the results that I got from it. I also had the Canon 17-55 later on, but only because I missed USM (and full-time manual overrule) on the Tamron and the only thing I shot was sports so...

I think so yes. For your budget it is a very good choice. I really like the constant aperture over the variable aperture of the canon 15-85. The f2.8 gives you more to play with and to be honest f2.8 really pushes your photos into a new dimension. Image-qualitywise the Tamron does a real good job, also read Bryans review of it. I was very pleased with that lens.


The only big downside vs the canons is the IS system that the Tamron lacks, but since you're used of shooting without IS I doubt this will be a major issue. But I could be wrong.


Also this way you keep to save some money which you could take apart for saving for a 70-200 f4L for your tele-needs later on. This is exactly the lenscombination I started with and I enjoyed every single bit of it.

It's known for it's wide constant aperture yes and therefor can make your picture much more interesting.


The main reason I why I wouldn't want a 15-85 is the variable and small aperture. I really don't like it, it gives me less control. And there are a lot of times I'd rather set my aperture at f2.8 than at f5.6 wide open. A lot of times f5.6 just doesn't do it for me and I need to increase my ISO or decrease my shutterspeed for either one and I just don't like that.


About missing focal length. The 15-17 difference I wouldn't miss. 17mm is wide enough for the normal use of a wide-angle. So unless you live in the grand-canyon or something, 17 will do just fine [:P] 50-85mm is a very noticable difference and you'll find yourself wanting to zoom further than 50mm sometimes, but to be honest I would rather buy a tele-zoomlens for those occasions because often 85mm won't work either []


I got to go swimming now, didn't notice time went by so fast[:O]good luck with your decision, it's a hard one [] If you have the opportunity to try some of these lenses....it is worth it.
