I figured I'd go back and post a photo. Since most people are talking about the 24-60 or the 24-70 non-HSM.

Seriously, the HSM version is a whole new ball game. I'll leave you to the sigma website or ebay to compare and contrast.

If that's "hideous", I'm sold.

Those photos are just smooth in the eyes! You should start a Sigma zoom lens club or a club of this lens only.

Here'a a sample photo that shows the color and sharpness performance of the old version of the sigma 24-70. its contrast is higher than tamron.
Btw it has the fastest AF i have ever seen. even faster than fa 50mm.



you can check the original size: Flickr Photo Download: gŁnebakan - sunflower
wonderful shot!

thank you. as you know 70ltd has larger f stops, so bokeh is better than sigma, then 70ltd rendering is brighter than sigma. 70ltd's shadow and highlight ratio is very good balanced. All in all 70ltd is a gem. i preserve sigma for general purpose and workhorse applications. both of them good lenses.

I've been shooting without my normal B+W circular polarizer on this lens a bit lately, sharpness and CA have been improved (duh), and I'm quite happy with it. Still not as sharp/micro-contrasty when compared to my best Canon and Pentax fast primes, but it's very usable and 8x10 prints are absolutely no problem, even wide-open at 70mm (which is supposed to be it's worst).

Horrid Facebook hosting:

I forgot! I have a Picasa account as well, and I recently did a steam-punk inspired shoot with some friends of a friend. One of the images got picked up as a Google/Picasa "Featured" photo:

Here's a link to the whole album (all shot with a Canon EF mount Sigma 24-70mm f/2.8):

the only downside of the Tamron is it's slow and noisy AF speed, zoom creep, built and QC issues (centering defect). getting a lemon is the last thing that you would want. it is said that the Tammy is a monster on an APS-C dslr, but not as quite as great on a full-frame but still display an excellent center sharpness. although what confuses me is that the MTF results on a FF has an outstanding score as compared to the APS-C, but the APS-C verdict is a lot higher than the FF. I dont know how photozone arrive or use and interpret these MTF results, but it seems it is inconsistent or does not reflect on the final conclusion about the lens. could anyone explain how a lens with a 3000 MTF mark on a FF gets only a 2 and a half approval, while a 2000 MTF mark on an APS-C gets a 4 approval rating. maybe photozone mixed up the MTF results?
I don't know for sure but sounds like you are talking about the Tamy 18-250.

The Tamron 28-75 F2.8 that i have is very sharp, does not have any zoom creep, just the opposite, is a pretty lightweight walk around lens despite its fast F2.8, AF is pretty good i think - it burps once or twice and is there. I bought it new recently for $400 plus. I think the price is why folks are not going for the Sigma.
