| I was thinking of geting the Sigma EX 24-70mm F-2.8, But now I realise Canon EF-S 17-85mm F-4.0-5.6 IS USM is only 150 euro more expensive. That's not such a huge difference but I really have no Ideea wich way to go. I saw tests with both the quality is verry good on both, but I don't know weather I should go F2.8 and 150 euro cheaper, or IS, USM, a bit larger range, but loose the F2.8 and an aditional 150 euro. Hmmm... What would you guys do? |

Hhhhmm......I think I would personally go with the Sigma, there is a big difference between 2.8 and 4.0 or 5.6. Is the Sigma 2.8 throughout? If so, then I would definitely go for that one.

I have the Sigma (which I love) but I think that the Tamron version has the edge.
Certainly go for the f2.8 |

IMO the "IS" is not a big plus when your at the 17-85mm range. The closest "L" lens with "IS" in this range is the NEW EF 24-105mm f/4L IS USM.
So if you are willing to give up the fast 2.8 I would consider the new "L" lens with "IS" above. Its f/4.0 through out with "IS" and "L" glass. It also gives you longer range (105mm) where "IS" is a plus. The link above will take you to canons web site where you can find the MTF chart for the lens.
EDIT: Another consideration is the Tamron SP AF 28-75mm f/2.8 XR Di for Canon @ less than $400.00 it is a great lens. Look at some of the scores this lens has produced and also look at the quality. Very nice lens.

An interesting suggestion, but it does sort of ignore the fact that the L glass is THREE TIMES the price of the Sigma in the original post.

Thanks guys that's what I thought too, I think I'll go for the f2.8 too you are right the IS doesn't do much on 85mm, and I have a friend with the sigma it has a hell of a noisy motor but preety fast, I think I won't trade the f2.8 for usm and an extra 150 eur. I have read a few reviews and from what I hear there sigma has got better quality than the Tamron, so I'll stick with that for now.

Have you considered the Tamron 28-75mm f/2.8 XR Di? Maybe it's not wide enough for you since it only starts at 28mm. I received an excellent copy of this lens and I am very happy with it.

I have the 17-85 & love the IS. Have shot many images at very low shutter speeds.
You have the added advantage of a greater DOF when you don't have to shoot at wide open apperatures, HOWEVER, often shutter speed is more important for freezing movement.
I have the 50mm 1.8 and if I need the fast shutter for low light action I use that.
The 17-85 is a fantastic all use walk around lens.

Does that rotate on the front when it focuses? From what I hear it does and I kinda don't like that the Sigma has the front steady all the tim, I like that it's verry good when using filters such as gradient grey and polarisers wich are a pain on lenses that rotate in front.
@aKiwi, as SDW65 sais and many other people also told me the IS mot so important at that range. That is usualy more helpful on larger range zooms. Sigma has f2.8 and that compensates alot shutter speed in lower light also. However if you wish you are welcome to stun me with some great unprocessed images at lower shutter speed send it to me on if you can on titi100@gmail.com. Thanks!

for the same price you could get the:
28mm 2.8
and
50mm 1.8
and
85mm 1.8
and
an extension tube
giving you a 28-85 superfast macro :)
I know, that's not what you asked ... i'm just sayin' you could.

I've have both the Tamron SP AF 17-35mm 2.8-4 and the Tamron SP AF 28-75mm 2.8, both are tack sharp, both rival their canon counter parts and both together cost less than one of the canon equals.
They are both Internal Focus (IF) the front element does not rotate.

No front rotation. The focus ring moves when autofocus kicks in. The glass in front and the filters attached to the end of the lens DO NOT rotate.
