I think you should go for the Nikon - otherwise you'll always have doubts! Neither of these images would convince me a Tamron was better than the Nikon!
Here's a couple I like with the 17-55mm
Sorry...but they're no sharper than what the Tamron will deliver.
General consensus in reviews I read seems to be that, except for the extremes, the quality of image is on par with equivalent Nikkor, but at half the price.
Oh go'on I'll swap you 3 Goats and a Pot Belly Piglet for the Nikkor LoL (so I can show people what not to buy) LoL I am a Canon man after allDidn't expect you to say anything else - but I won't be swapping my Nikkor for a Tamron at any price.![]()
Don't really do flowers but I checked my Lightroom database for 17-50 and I have this.

Bearing in mind this is on a Fuji S5 Pro is a bit soft due to its strong AA filter. but it might give you an idea?
Just a warning that the Tamron's AF motor is considered to be one of the loudest around. I certainly couldn't purchase the lens having heard one unfortunately so I went for the Sigma 18-50mm f/2.8 instead.
To the user above "AWP", you are embarrassing yourself with such comments. Don't put down a lens when you haven't any experience with it. I'm going to assume from your blunt snobbish remarks that you have none with this lens and are merely brand scaremongering based on your logical opinion of anything non Nikon. If you have experience with one then I take the above back, but would insist you must have had a bad copy as this lens is considered to give massive bang per buck with very good image quality even wide open.
it aint that loud, and I'm 99% sure the canon one is better than my tamron so I guess the nikon would be too, more cash more quality. Yeah the tammy is great bang for buck but don't get personal with members
this thread interests me because I have a tamron 17-50 but might upgrade to the canon 17-55 IS
it's supposed to be pin sharp.
now my tamron is pin sharp and amazing...at times, otherwise it's just pretty damn good
also I've missed the odd 'critical' shot with the tamron
will give it a good work out at the next fight gig on a weeks time.
now however, tamron have released the 17-50 VR.....nikon first, then canon maybe later in the year.....
it's all to play for, I will probs hire a 17-55 IS from LFH in november (I have a wedding to go to) and to a compare for my own benefit before parting with oodles of cash!
