what are the numbers for that shot andy? (focal length & aperture)
i'm really considering this lens from digital rev at the minute, the other consideration is the 30mm 1.4 sigma
I don't think anyone underestimates it.
There seems to be a reasonable amount of consensus about this, so let's change the question. How many of you would choose the Tamron over the Canon or Nikon equivalent (I have no experience of any of the other alternatives) if cost didn't come into it?

Good to know as after much research I ordered one and waiting for delivery now. Couldn't find a bad word said about this lens.
Also, for anyone looking to buy one, cheapest I found it at was £250 here:
http://www.procamerashop.co.uk/product/Tamron_SP_AF_17-50mm_F%7C2.8_XR_Di_II_LD_Aspherical_IF_(Canon_Mount)_34625
Seems a good deal as they are selling for around £220 2nd hand on eBay!
i got one and i like it but the noisy auto focus and innacuracy of it all is poor imo.
you get what u pay for!

Sounds a little harsh from what i've read..... but as you own one, can't argue I suppose.
Is the AF only a problem on Nikon bodies without AF Motors? ie my D3100?
Or is the AF inaccurate and noisy full-stop?
I was hoping this would be my next step up lens...... now i'm not so sure.![]()
Non vc? Does that mean no IS?
Possible to get away without the IS kn this lens?

im not trying to put anyone off with this lens, its a great lens for the price. i will upgrade to a L lens equivalent in the near future though.
If anyone is using the Tamron 2.8 17-50 on a non AF motor Nikon i'd love to hear your thoughts on it. (D5100, D5000, D3100, D3000, D60, D40, D40x etc)

It doesn't matter. For at least a couple of years, all of them have been sold with the inbuilt motor - so it doesn't matter if you are using it on the lowest consumer DX body or the top end professional DX body, the AF will be determined by the Tamron lens motor, not by the body.
Thanks for that..... I "thought" that the body would take over AF duties if it had the power to do so.
I'd have "thought" the AF motors on bodies would be better/faster than onboard the lens? (there's me thinking again!)![]()
All Canon EF/EF-S lenses have motors in the lens. None of the Canon DSLRs have motors in body.Does USM canon lenses have the AF motor on the lens or camera?
Does USM canon lenses have the AF motor on the lens or camera?
I never understood this thing with Nikon and motors in the body - why is that?
