5.0 out of 5 stars The best general portrait zoom lens!, July 6, 2006

This review is from: Sigma 24-70mm f/2.8 EX DG Macro Aspherical Large Aperture Zoom Lens for Pentax and Samsung SLR Cameras (Includes 3 year US Manufacturer Warranty) (Electronics)

I've used a number of lenses in the 28-70mm f2.8 class from Tokina, Tamron, Sigma, Pentax and Nikon. I can honestly say this is my favorite lens in that class.

I shoot with Pentax, Nikon, and Fuji cameras and the Sigma 24-70mm 2.8 DG lens is the only lens that I bought two of (one for my Nikon /Fuji cameras and one for my Pentax cameras).

I wouldn't call it the best lens in the world, but if I had to choose only one zoom lens to cover the 24-70mm focal lengths then this lens would be the one I choose.

I went through a second copy to find a good performer, but for the result I'm getting on my k10d, it was well worth the trouble. My first copy was bit soft at longer end and it wasn't what was expected from the review I was going by on the canon mount provided below. The exchange process was painless via amazon, as usual.

BTW, I've also tried Simga 18-50 f/2.8 EX DG and I've returned it in favor of Sigma 24-70 f/2.8 EX DG.

Once I got the second copy, it has been pleasure using the lens. I'll just point out the highlights:

Pros:
1) Excellent optical quality, no issues with CA or distortions at all focal length.
2) Image Quality at f/2.8 is very good and outstanding at stop down and peaks at f/5.6 in all focal length. If you're into sharp images this lens will deliver.
3) AF is relatively fast and not too loud.
4) 24-70 is still a great range for indoor use even with 1.5x crop factor.

Cons:
1) it's big and heavy.
2) related to size, better to use external flash due to shadow with built-in flash with lens fully extended/at the widest end.

All in all, this is the lens I use for indoors most of the time, however it performs even better with full sunlight at outdoors. If you don't mind the bulky size or the extra weight, this lens will be one of the best glass you can buy in the range of 24-70mm on a pentax mount. If I ever make a switch/or add canon/nikon body, then this is the lens I'll buy again for the other body.

4.0 out of 5 stars Great Glass!, December 15, 2010

I just got this glass for my pentax, I must say it's everything it said it is when it comes to sharpness and it does look great on my camera.

Drawback: Because it's such a big glass, I can no longer take pictures with the built in flash, if I do, it shows a shadow (part of the glass) so I have to always carry my exteral flash as well.

Otherwise it's a great glass! it works for macro and regular picture taking so long as you focus on the subject you are shooting.
