Canon EF-S 17-55mm VS Sigma 17-50mm VS Tamron 17-50mm?

pete shall I post the digital picture visual comparison again?

15 mm cleans up nicely in Lightroom -- automatically with the lens correction plugin

15-23 mm it is only 1/2 stop slower than f2.8 and it is sharper at f3.5 than the other zooms.

the recommendation had 35 f2 and 50 f1.8.  the 15-85 IS between 15-23 at f3.5 would have done fine with the photos you posted

I need help deciding on a new better quality kit lens...

I am shooting with a 60D that I just got so I'm sticking with a crop lens to get the full wide angle that I need. Please help me pick (with evidence why) between the three lenses.

My budget is about 1000-1500$ but I also want a new Canon flash... Do you think I should go with the Canon and wait for more money to get the flash or sacrifice IQ for a third party brand? Or is the third party somehow better for cheaper? Please help never bought any third party lenses before! I am open to any suggestions, but please keep in mind I would it for everyday use (landscape/portraits) and I prefer a wide angle since I don't have any good quality wide lenses.

1. Canon EF-S 17-55mm f/2.8 IS USM Lens (999$)
2. Sigma 17-50mm f/2.8 EX DC OS HSM FLD (619$)
3. Tamron AF 17-50mm F/2.8 SP XR Di II VC (549$)

All of these prices are from Amazon, the Tamron has a 100$ mail in rebate offer.

PS: I would like to use the lens for some video also... But, mostly photographs.

THANKS FOR THE HELP!

$639 15-85 IS get the vello hood - it is only 1/2 slower - ie, f3.5, between 15-23

$639 + $289 + $99 + $254 = $1284 in budget and much more powerful

Terrible advice. The 15-85 is as slow as molasses and extremely overpriced. Think about it as being the kit lens but 30mm longer on the long end yet they charge $600 for it.

You'd be better off sticking with your kit lens and getting a 50 1.8 and 85 1.8 for your long end if you went with his route.

Also the 430 is a bad flash for the money. I'd get the Yungnuo equivalent for $100 less which has ETTL and is more powerful than the 430 if I recall correctly.

the terrible advice is your lack of experience with lowly equipment - 450d, 85 f1.8, borrowed 18-55 and a third party flash...that you think you recall --that has sync issues btw. In another thread you recommended manual flash

the 15-85 is sharper than anything you own and only a 1/2 slower 15-23 - which is just as good as the f2.8 with NR -- because it is sharper -- and sharpness trumps 1/2 stop of noise. LR corrects the lens perfectly. It is L at these settings, then the poster would have F2 at 35 and f2 at 50.

430 exii is regarded as an excellent flash for the dollars.

get some good gear. 450d is known as landcape gear not portrait gear. the cheapness of your behavior shows in your posts. Event shooting btw mandates 2 cameras or you get in trouble.

Look all these evening shots are from Sigma 17-50/2.8 OS at F2.8 wide-open. At 50mm side, 15-85 will be almost double slow at F5. These photos were all taken with hand-held from Sigma 17-50/2.8 OS (or sort of, such as put camera on the bag that sit on top of garbage can to absorb vibration) but absolutely no tripod.

EF-S 15-85/3.5-5.6 IS has severe distortion at 15mm side +3.0 that is very big. Its max aperture is,
