For me, right now, it's my 17-135mm. Really depends what type of shooting you want to do. I need more wide, and will probably get a 10-22mm for my hiking lens.
you mean 18-135mm right? haha![]()
Can afford to travel the world but not afford another lens?I just travelled the world with only a 50mm. Big mistake. I often couldn't get entire landmarks in one shot. Next time I'm bringing a 24mm.
The new 15-85mm is very good if you want to cover your wide angle shots while travelling. I used it while on a trip to Shanghai and Tokyo and found that I ended up using the wide end more than the telephoto end. The 15mm really helps to let me capture landscape and building shots that I couldn't otherwise have gotten. There's only so much space to back up when you are standing on a sidewalk. Whereas, getting a bit closer to the subject usually wasn't too much of a problem; unless there was a river in the way, heh.

if you can, get the 18-200. End all Be all. The End.
I have the Tokina 11-16 f/2.8 but not the Canon 10-22 f/3.5-4.5. I mostly used it for skyline shots of the city. The lens was stopped down to f/8 or f/11 most of the time so the f/2.8 didn't matter. I wouldn't carry either of them around as a general walkaround lens. It was way too much of a hassle to change lenses to get a shot between the 15-85 and the 11-16. I ended up keeping the 15-85 on most of the time and only breaking out the 11-16 when I knew I was going to go ultra wide for a series of shots at a location. But if you could only use one of the two lenses then I'd suggest going with the canon. The extra reach really helps unless all you plan to do is take lots of wide angle shots.
is the 15-85mm for ~$650 worth the upgrade over the 17-85mm for ~$300?
$300 for a new 17-85mm is pretty good deal. When I was buying the 15-85mm last year it was $650 vs $500 and the image quality and wider wide angle was worth the extra $150. Buy the best lens you can afford. If you keep the lens for 2-3 years, you'll still be able to sell it for most of the cost when you are done with it since Canon doesn't update their lens models for years and years.
The 17-85mm IS is pretty slow at f/4-5.6 compared to the Tamron. So it depends on whether you want more reach, or a faster lens.alright, last question: canon 17-85mm vs tamron 17-50mm f/2.8 non-VC ??
