Sigma 24-70 f/2.8 EX HSM

Tony-S · 20th of February 2009 (Fri)

The new HSM model is now available, and I'm still learning how to use it...

Here's a shot at 70mm, f/2.8, 1/80", ISO 200 on the 5Dii with the 580EX II and Stofen attached. The lens is capable of very creamy bokeh, is a little warm, but easily managed. In this shot, I bumped up the blue channel +15, did a curves adjustment with just the tiniest 'S' curve, then did a 100/2/3 unsharp mask. EXIF data should be intact.

I think they're principally aiming it at the Noink crowd (almost $1,700 for their 24-70 f/2.8 ), but keeping it in range of the brick ($1,200) for us Canon folk. I suspect it'll be down to $800 or $750 in a year from now. But it's tough to know for sure.

It is more compact (it's tiny compared to the brick) and supposedly has better optics. I've not seen the non-HSM model so I cannot provide a direct comparison. The zoom is also in the opposite direction from the non-HSM (and now the same as Canon's). It sure feels beefy. I'm hoping to get out for more shots, but work has me rather swamped ATM.

How is the weight on this lens? How about the build and quality?
I was looking at it on the BH site. It looks small.

It is very nice and compact - a lot smaller than the brick and Noink's 28-70. It has the typical Sigma EX build and feels quite solid.

post more pictures i want to get lens!

can you post unprocessed image at 100% crop?

tanks in advance...

Tony-S · 26th of February 2009 (Thu)

Here's a full-frame (5Dii) and 100% crop unprocessed at f/2.8 and 70mm. I don't have too many others yet. It is warm, which is typical of Sigma lenses, but otherwise I'm very, very pleased with it.

Tony-S · 26th of February 2009 (Thu)

This 70mm series is from f/2.8 to f/8, shot from a bit further away than the previous images (around 8 feet to subject) on the 5Dii. Other than levels adjustment, no pp applied. As you can see, contrast and sharpness improve as the aperture gets smaller.

f/2.8:

And f/8:

I've spent some time with the lens today and here are a few observations:

1. The lens has excellent control of chromatic aberration - there is virtually none.
2. It has excellent flare control (better than my 17-40L) and the hood does a very good job of mitigating flare.
3. It vignettes at 70mm until f/8, and 50mm until f/4.

A couple from today.

And a couple more.
