This is a 100% crop taken yesterday with my EOS 20D and my Sigma 18-50 EX f/2.8 (50mm, f/4, 1/125s, ISO100). No pp whatsoever - just adjusted levels and colour temperature in RSP.

There aren't too many zooms in this focal range, at this price point, that can deliver this level of detail resolution. I love mine!

Ok, do you have any 100% crops you could provide which show how soft it is? Remember this is a 100% crop with no sharpening applied. If it is soft, then I'd be amazed to see what a sharp lens can resolve.

lol - I wasn't having a go, was just really surprised at the suggestion that there were lenses that could resolve so much more detail, as to make these look soft.

I have the Sig 17-70 and I'm very very happy with the sharpness...
Check out some shots here tho most are close range. Absolutely NO sharpening.

It puts my Canon 100-400 to shame ( I think it needs calibrating)

Enjoy

It's a great lens. Check out the MTF charts on it at photozone. It's center performance is hard to beat, even a few of the famous canon primes can't do as well. But then it falls apart at the borders....

This is the reason i've now passed over the sigma 18-50/2.8,it just doesn't measure up against the competition.
Yes it IS a good lens ,but the new tamron especially seems to be better.
The new canon is *much* better...but costs an arm and a leg,LOL, which rules it out

It does fall off at the edges a little, but for the money, it's sterling! I am also interested to see how the new Tokina and Tamron do, but can't see the difference would be so great to make it worth my while selling this lens. I am thinking of getting a wide(ish) angle fast lens like the Siggie 30mm f/1.4 for indoor shots ( whilst I love my flash, I prefer not to have to use it!)

Umm, sorry, but if you have little room to complain, and cannot find one thing to be critical about, why would you replace it with the Tokina?

After viewing these, I can't find one thing to be critical about, particulary for 375 dollars:

I can't speak for the Tamron, but I'll probably replace the Siggie with the Tokina. I worry my wife that if the Tokina isn't superb, that's it, I'm selling some funiture and buying the canon. :)

Looks pretty darn sharp to me. The right eye (left in the frame) has lots of detail around it.

Actually...I also heard or read from somewhere that the Sigma also isn't a true 18mm at the wide end either. I heard it 19mm, not a huge difference, but still.

Anyone else hear about this or care to confirm?

Still a killer lens though nonetheless and one that I'm definately still looking at, although I'll probably just continue to wait to see how the Tokina to prevent possible "buyer's regret" later on.

Never heard that and, frankly, even if true I don't care. The day I worry about being 1mm short is the day I know I have truly lost it :lol: :lol:

Agreed about the Tokina. Promises great quality and best of breed build. Shame it won't have a USM/HSM style motor. That would be a real killer lens.
