hey everyone. i think i am going to spoil my father rotten this xmas. i think i have decided on a eos xti body but am trying to decide on a lens. the tamron 17-50mm f/2.8 and sigma 18-50mm f/2.8 both appeal to me, but i am having a tough time deciding between the two. i have read a few reviews of each and it seems like a draw. any help would be appreciated!

thank you.

Hello mwahlert,

Since you say it's a draw, I'd go for the Tamron since it's slightly wider. There's a few other options since both of these lenses are about $500 USD the Canon 17-85 could perhaps change your decision.

from my research the tamron seems like a slightly better lens.

the canon 17-85mm is a nice lens - as it includes image stabilization, however, the tamron and sigma lenses on paper are much faster with a fixed f/2.8 - vs f/4-5.6 on the canon. how do you think this stacks up in the real world? i was aiming for a fast lens so it would be easier to achieve bokeh.

Depends what kind of photos your father likes to take. If he loves portraits with a very blurred background, then yep, the f2.8 models will be better in this respect.

That said, the Canon can zoom-in closer, so can still achieve a blurred background at 85mm f5.6.

See the second photo in this gallery for an example:

http://www.cameralabs.com/features/Cano ... age5.shtml

I'd personally go for the Canon because of the longer range, image stabilisation and USM focusing.

PS - to see what you can do at 55mm f2.8, see the second photo in this gallery:

http://www.cameralabs.com/reviews/Canon ... age5.shtml

For the ultimate bokeh though, why not go for the 50mm f1.8 or f1.4? Affordable and very very bright!

A bit of an echo of what Gordon said, the Tamron and Sigma zooms aren't for a lot of portrait work, it's meant for an all-round lens. The Canon Primes are a true portrait lens with that f/1.8 or f/1.4 aperture, no distortion, and very very sharp optics.

the only thing scaring me away from the canon 17-85mm is this review

http://www.photozone.de/8Reviews/lenses ... /index.htm

i am looking for a great all purpose lens - does the large aperture of the tamron hinder it in some way?

according to reviews at photozone.de the tamron seems to edge a win over the sigma in my book. it even sounds like the lens serves as a decent macro.

Hi.
A friend of mine has the Tamron 17-50 f/2.8 and he's really happy with it. He says it's very sharp and works great.
I'm having the Tamron 18-200 (which can't be compared to the 17-50 of course), and decided to buy the Canon 17-55 as a general lens (1st step to change my 18-200 to 2 lenses kit). I think I prefer Canon over 3rd party lenses. Also the Canon is USM (which is important to me) and IS.
Anyway, according to my friend, you shouldn't be disappointed with the Tamron 17-50.
Liron.

IIRC USM stands for ultrasonic motor? meaning the focus drive is in the lens?

what it boils down to is that i am looking for a solid (well built), multi purpose lens - at a reasonable cost.

Perhaps the Canon EF 28-135mm IS USM?

Probably not the widest angle but with a decent telephoto reach! :)

Keep me posted!

The tamron 17-50 is nice but has reliability issues. It might take a couple of them to get a good sharp copy.

Hi mwahlert,

Just a "heads up" to say I've moved this topic into the Canon forum as its title refers to the Canon Rebel XTi. It was a tough call but as this is a lens choice specific to a Canon model I think it's tidier to have it here. Might also get some more replies. 8)

Bob.
