Here is the unofficial test of Sigma 24-60mm F2.8 EX DG compared with FA28mmF2.8 & F50mmF1.7 at the same apertures. The latter two are the only lenses I have in that range.

You can have a quickie comparison by clicking on slideshow at

http://www.pbase.com/danieltong/sigma24-60test

For median details you may click the first file and the file number and exif will give you all the details

All the smaller files start at

If you feel like it you may go through the full size (and pixel ) comparison ( huge file warnings!!!) . That happens to be the proper way if you are serious.

The full files start at

You can easily focus on area that you would need to form your opinion.

Download the jpg to your harddrive and open two windows for comparison.

This is my first zoom lens and so far I am happy with the first 50 or so shots. AF is fast even compared with my FA135mm2.8. It is smaller, lighter and more professional than I thought.

Any opinion: Keeper, so-so, garbage or what ?

I now know that its Canon mounts were available since 2001 already. And Pentax mount just came out earlier 2007. I got it new from Henry at Can$260 +$10 shipping+ tax . That came with 10 yrs warranty. Not bad if I need it (say for rechipping for the 2010 K10D x generation) ?

I find out that for simple walk around , party and family occasion, this FL range is the best.

Keep it...I like the exposure and contrast in comparison with the 28mm in particular. The dark clouds are well defined in the comparison shots using the 24-60 and the sign lettering is well exposed. The 28mm lens shots the highlights in the clouds are blown out and the sign lettering is too dark. I like it. If you ever plan on giving it away I'll send you my address and send the shipping cost.!

It's a brighter, higher contrast lens than the 28mm - that can work either for or against you depending on the circumstances (something I found out with my K-mount Tak 135mm). Brighter means better colors and more pop to the pictures, but it also means that they can sometimes lose detail that a lower contrast lens might capture. I looked at the slide show and it seems quite sharp, expecially for a zoom. Looks like a useful keeper lens to me.

Let me see if it is easier to ascertain

The Sigma zoom at F2.8 at 50mm followed by F50mm


















The zoom at F5 followed by F50mm















The zoom at F8 followed by F50mm








The pict tell all. Wide open, there was no match at all. But at F8, they are close and difference is subjective

Interesting comparison Daniel. One thing I noticed is that wide open, the zoom seemed to focus more towards the back of the frame but at f5 it seemed to focus closer to the front. The F50mm 1.7 is a great lens, so the zoom is doing good just to compete. I think the difference was most noticable in F5.

LBA shots : these are random test shots of Sigma 24-60mm at F5.6 which is my favorite .



















One thing I have found out is the usefulness of 24mm and 40mm - something that I did not know before

p.s. I post this also in the dark side forum - Canon lens - as well. That is to drive them crazy as there is no alternative/comparable on the dark side at all. The whole set up of a walk around lens like this with K100D costing around $800 . And with I S/SR/VR, that is a pain for any Canon user.

I had a freind of my son-in-law (die-hard Canon user) get rid of his canon and buy a Pentax after using my K10D and all it's lens...He was totally blown away with all the different lens it could use...

Very nice pictures in the second lot. It looks like the laptop's monitor needs dusting, doesn't it?

I am the type of people putting on a spin of things to cover me screwing things up. Ok I have dirty laptop screen so you can see the lens performance better that way re the long hair by the headphone.
