Sigma 18-50mm f2.8 VS Tamron 17-50mm?

[Sandi]

I'm looking at both of these lenses & trying to decide which one to go for.

Please can you give me your views.

Thanks in advance

I have owned the Tamron 17-50mm (NON-VC) on Nikon (used on D90) and it was a lovely lens. For the price you couldn't really complain.. Mine was very sharp even from 2.8 and also very even performance across the frame which was important for me as I usually used it for landscape. AF was good as I had the older screw drive version, apparently the built-in-motor one is not the fastest for AF and a bit noisy, but apparently it isn't that bad..

I have never tried the Sigma in question, but you can see reviews of both lenses below..

Thanks for those. Interesting!

Now, I'm thinking to rather get the Sigma 17-70mm Macro? Argghhhh! This is frustrating!

Just to explain - I shoot mainly portraits so am looking for a lens (other than my 50mm f1.8) for that. Oh & I own a Canon

My fiancée uses the 17-70mm lens and loves it, good value for money.. ;-)

OK so you are looking for a portrait lens? so what is the deficiency with the 50/1.8, might help myself or others recommend an alternative.

Oh no, I LOVE LOVE LOVE my 50mm f1.8 & hope to eventually get the f1.4 lens.
I just need a portrait lens that gives me a bit of zoom capability as well as enable me to zoom out a bit if I'm in a tight space.

I think the 2 will make a nice combination for me & give me a bit more flexibility.

Tamron 17-50mm (NON-VC)
18 is too long.

I haven't got any example pics of the Sigma, but I compared the Tamron 17-50mm VC and non-VC versions here.

Have you considered 24-70 f/2.8

[Roosta]

I have the 18-50 Sigma, ball tearer of a lens, very sharp. The Tamrom is also a cracker, there are some good Camera shops here in Perth to try the lenses out. The Sigma is lighter and thats about the only real difference I found, someone mentioned the 24-70, great lens, but what Canon body are you using, The 24-70 is more for a full frame not to say you can't use it on a crop body.

I went through this dilema for the last month, it came down to feel and the Sigma won for the F2.8, very very sharp. I wanted it for a general purpose walk about, and to use for longer exp shoots.

Good luck.

With Sigma, the prefix DC is for Crop body sensor, DG for full frame.

The Tamron Dii for aps-c Crop body.

Also try dpreview.com for a complete review on these lenses, they couldn't split then, so you need to get a feel for them.

Hi! I have the Tamron 17-50mm f2.8 (non VC version and am very happy with it - I have a number of other lenses that complement it). I wanted it for the f2.8 aspect in portrait work but actually recommended the Sigma 17-70 f2.8-4 to my mother-in-law because it would provide her with a useful focal range on her 550D and apparently is also quite sharp. The 17-50 Tammy is great, but the 17-70 Siggie would give you greater range. Oh the pain of decisions!!!

Hrmm... i may be way out...
Are these lens in comparison to the Canon 17-55mm? or even the 24-70mm?

I think the problem is Ed the Canon 17-55 2.8 is more than twice the price of the Tamron 17-50 2.8 non VC, yet many say the Tamron is nearly as good. I guess it all comes back to $$ in the end, Sandi could buy the Tamron non VC and a Canon 50mm 1.4 for less than just the cost of a Canon 17-55.

according to this the tammy is much sharper than the Canon... at a more affordable price as well.

I recently bought the tammy and i'm stoked with the images it helps produce

Got to agree with you, I recently got the non vc tamron and the IQ really knocked me out, this one will not be leaving my camera bag for some other lens.

I also had the Tamron 17-50 (NON-VC) and it was a cracker of a lens, very sharp a a great price for a f2.8. Only sold it as I am ramping up to go FF and replaced it with a 24-105. I highly recommend the Tamron.

I know that this thread has been going for some time now, but I would just like to add that my Tamron 17-50 (NON VC ) when mounted on the 40D is sharp and quick to focus. Another recommendation for this great lens.
