Just realized that Sigma announced a new version of the 24-70mm 1:2.8 with HyperSonicMotor. 24-70mm EX DG HSM @ Sigmaphoto.com

i wonder why they didnt include OS in it this time... concidering the performance of the old version, the new one with HSM AND OS would have been serious competition for any 24-xx(x) standardzoom out there...

nevertheless, it has HSM now! :)

This one interests me. I can't wait to see reviews and pricing on it. I think it would fill in nicely for portriats of my non-stop 2 year old where IS wont help freeze motion. Plus the HSM to focus faster as she moves around.

Has anyone heard anything from Sigma about when these lens will be available? It's been a month since Photokina and we still haven't heard a peep about when it'll be on sale.

Well, the optical construction is totally new, the body is shorter and the shrink factor is higher* than with the old non-HSM version. As I've seen no MTF charts so far only a test will show how the new version performs.

------
* the old version focusses down to 40cm giving you a magnification of 1:3.8 while the new one goes down to 38cm but only produces a magnification of 1:5.3. So the effective focal length is shrinking faster with the new lens when focussing down than with the old lens.

I ran accross a video, I believe on youtube, of one of the Sigma big shots being interviewed at photokina and he said December for the release of the new 24-70.

They've started appearing on eBay for about £550 - £600. That's a lot less than the RRP of £899. I hope they start appearing in shops so that I can get my grubby little hands on one!

I think this will be better than the Canon & Nikon pro 24-70mm. (& cheaper) :) I can't wait for the samples.

In a random search around UK e-tailers, they do seem to be in stock at a few places. Lowest price I've seen so far is £750 which is only about a 25% saving from the equivalent Canon. That isn't quite enough of a saving for going 3rd party to me. So for the price it would have to be optically as good as the Canon to stand a chance... Then again, it is just released so maybe the prices will drop some more in a month or few.

Actually, if it is for sale already, where are the reviews? Haven't managed to find some yet...

The new Sigma looks to be quite a small lens, which is a good thing. It would be interesting to see the Photozone review (if they ever get the lens). The thing I'm most wary about regarding Sigma lenses is the autofocus accuracy.

I guess there's a secondary question to answer too. If you already have the Tamron 28-75, would it be worth upgrading? The bit more at the wide end and HSM are nice to have, but are they enough for the price? Guess we'll have to wait to find out.

The thing with the Tamron is that it's such a good lens for the price. I really wasn't expecting it, but I can believe reviews that claim that the Tamron is slightly worse than the Canon 24-70L wide open, particularly in the corners. Otherwise, it really holds its own against the much more expensive lenses.

Like you've said, the main advantage of the Sigma is the HSM. The Tamron has a dinky little electric motor that sounds slightly iffy.

yes the HSM on that 24-70mm is very silent, i can't hear any sound (which is sometime not very good because i'm not sure if the focus is doing the job in tracking or not hehehe).

Isn't there an indicator in the VF that lights up? I can live with a totally silent focus.
