positive:Fast and silent AF, lovely colors, great IQ, Cheap!!!
negative:No focus hold, focusing-ring-rubber issues!
comment:Sharper than the Minolta
A bit less micro contrast and color appealing than the Zeiss.
A great "cheap" lens that offers "very similar" outcome compared the triple priced zeiss.

From my point of view here is an quick evaluation for the 3 mentioned lenses:

1- Minolta G has warmer colors and the most appealing bokeh though it is slower and noisier
2- Sigma version is faster, silent and sharper with nice overall colors
3- Zeiss is the sharpest with the highest micro contrast and more realistic colors. fast and great IQ. the only drop back is the price!

comment:It´s a very good lens in full frame. It´s my Second in List prefered lens, with minolta 80-200. For me is almost exactly in a900 as a77 with 16-50, but softer in 2.8. From f4 is amazing sharp.
The only problem (for me) is the next: some times use microadjust in +-0 and lok sharp, but some times need to adjust -3 or +3 to get sharper, some times. I really dont know why :P

comment:What this lens has going for it, is feature wise, this lens is the next closest thing to the CZ 24-70mm at around half the price. It has the desirable 24-70mm focal range and (near) silent & accurate AF. Good solid build quality (with the weight to match). All positives over the Tamron 28-75mm BUT the potential deal breaker here is the cheaper Tamron is meaningfully sharper wide open (especially at the long end).

If the prices were similar I would say it's a toss up between superior AF & focal length vs the extra sharpness of the Tamron. However with the price of the Tamron being a fair bit cheaper IMO it does tip the scales in favour of the Tamron unless you had your heart set on having the lens start at 24mm.

positive:-great sharpness
-great autofocus
-light sensitive 2.8
negative:nothing really
comment:Fortunately, I was able to buy this sigma 24-70 2.8 hsm two weeks ago. The feel is really first-class. It is not too big and not too small either. Autofocus is really spot on. So far, I haven't seen any hunting, even not in low light situations. The disadvantage of the minolta 28-70 2.8 G (which I sold) that its mfd was not so good. Apart from that, it had a really slow autofocus. The disadvantage of the tamron 28-75 2.8 is that in autofocus it frontfocuses. This Sigma 24-70 2.8 hsm is really spot on; no micro-adjustment needed on my sony a850, and not on my sony a580 and a700. This is really wonderful because only few sony cameras lenses can be micro-adjusted.
Would I recommend this lens? Yes, absolutely!

positive:sharpness, color, bokeh, HSM
negative:82 mm filter size
comment:This is excellent lens for Full Frame cameras. It's cheaper alternative to Zeiss 24-70 while not worse at all. Minor negative is 82mm filter thread instead of more popular 77mm typical for many other lenses in its class. Anyway, optically great. The exemplar I have needs no microfocus adjusting - every shot is sharp on A700 or A900.

comment:This lens was my choice to cover WA range on the A850 because the Sony/Tamron 28-75 are mot wide enough and the Zeiss is too expensive. The range seems limiting when compared to what I was used to on APS-C with the Sony 16-105. Until now the Sigma shows less CA than the Sony on the wide end in contrasty scenes. Bulky and quite heavy - but for FF and f/2,8 it seems that's it

compared to:Kit Lens, Sigma 100-300mm F4 EX DG APO HSM
price paid:900
positive:Build quality, this lens is a tank. Fast, great color, excellent focus that is very good in low light, filter sizes match my 100-300mm lens, pro quality portraits with interesting bokah, and the lens looks awesome on my camera.
negative:Cost. Not as sharp as top rated lenses in this class.
comment:This is a great walk-around lens. Many user complain about it's weight. Many times I not only carry this lens, but my 100-300mm as well, so this one's a feather comparatively and much more usable. Not only that, when I carry this camera, I usually flip the camera to my back and this combo carries very well that way.

The portraits are very good, you can see a few that I recently took on the sample image page. Some reviewers complained about the bokah as being overly busy, and when I first saw it I agreed, but after using the lens I really appreciate how I can get a full smooth bokah with my 100-300 and a much more defined edging with my 24-70mm. Check out the portrait I took of my daughter, I love the added sparkle I got from a bit of light breaking thru the trees, and how well defined the flowers are, yet are very much blurred and cause the photo to "Pop." I've become a big fan of this style of bokah. Now maybe I wouldn't if I didn't have the option of an extremely smooth bokah with my 100-300mm, but the combination of the two for me is great!

Speaking of combinations, I love that my filters are interchangeable. They are big, but I like how the lens works, and I like how it looks, so this size does not affect me in the least.

This lens is so good that I question weather I really need my 100-300 any longer, it's such an excellent all-around lens. But there are those times that the longer focus cannot be replaced.

I spoke about the sharpness, yes this lens is quite sharp, but it's not on the level of the lenses that cost twice as much, and you say of course not. Is it's sharpness worth $900, that's the question, and I don't think I can answer. My guess is no, that you could get equivalent quality for less, but probably at the cost of speed, or at the cost of hypersonic motor drive. So overall, this lens is really very, very good. But if your looking for the absolute sharpest lens in this category, this is not the number. But for me, $900 is my absolute ceiling for a single lens, so there you have it.

positive:Fast and sharp.
Constant 2.8 good for the X center focus on some alpha body.

Focusing and zooming does not rotate it's filter is a real plus point.

9 blades. Nice Bokeh.

Good egonomics, good construction. No zoom creep.

Really positive as compare to the CZ lens of the same reach has to be the pricing.

Smooth zoom. Fast forcusing.

Great as a travel and protrait lens.

negative:The hood as compare to the CZ is not on par. But I am sure many can live with it.

A tad not as sharp as the CZ 24-70 wide open ( F2.8 24mm ). Factoring in the pricing I can surely live with that.

Large filters required = $$$.

Have some flare issues but after removing the filter it disappears, must have been to the cheaper grade filters I installed. Have yet to purchase better quality to try.
comment:Sigma being a 3rd party lens manufacturer has really made leap and bounds on this lens for the alpha mount.

Many mention about sigma and their bad quality control, I differ on this aspect. The copy I had was sharp on new and it never gave me front nor rear focus tingy.

Sure the price for this lens might have been on the high side comparing to sigmas from the past but quality wise is there. Taking into account of CZ lens pricing I say this lens is a real deal minus the T-coating on CZ lenses.

On C size sensor this lens is good even thou it becomes a 36-105mm. Which indoor shooting might not be wide enough but at that range it makes for a great travel lens.

On full frame this fellow really shines.

positive:Sharp
Fast
Bright
Excellent Bokeh (check out my image in the samples gallery)
negative:Slightly soft edges at 2.8
Very slight yellow cast at 2.8, gone @ F4; would have given color a 4.5 if that was an option
comment:If the QC is variable on these, I must have gotten one of the best copies.
Sharper than the Sony 70-300G @ 70mm throughout the wide end of the aperture range, this surprised me. The Sony is very close @ 5.6 and about the same from 11 on.
Less falloff than the Sony at higher F stops.
Much sharper than the 35-70 F4 and very nice bokeh; unlike the 35-70.
Much sharper than the Tamron but that is a very old film lens that did not even carry the SP rating.

The zoom ring is smooth and the focus ring feels almost identical to the one on the 70300G, smooth and precise.
No zoom creep.
I wanted to give it a 5 for build but after reading the reviewing guidelines, I think only lenses built like the 70-200G would truly rate a 5.

Very sharp wide open!
negative:I havent found anything really to complain about. It has been a joy to use!

comment:This lens has been great! I think that it can hang with most OEM lenses! This lens seems to be a touch sharper then the Sigma 70-200 2.8 HSMII, But I already feel that lens is super sharp! It doesnt get much better
The focus is fast, silent and accurate! The colors are...a little different then the Minoltas. But now that all I have are Sigma lenses, I really just dont notice and PP to my liking if I feel the need.

The people that rated this lens bad...Just got a bad sample!! I wish that they would send it in and have it recalibrated and then post a review instead of saying this lens is crap!! There is NO way this lens is a 3.5 in sharpness!!! Im sure that the CZ is a little better maybe then this lens....But it also almost twice as much jack offs =)

comment: This lens has impressed me. It is very sharp, by direct comparison only fractionally less sharp than the 24-70 Zeiss. I had opportunity to try both consecutively at Ritz. I have no complaints. It is worth every dime I gave for it. I have experienced no hunting or slow focusing. Sounds like Sigma is having fit and finish problem in US. I have heard other top end high end manufacturer having similar problems though.

positive:Solid Construction, good ergonomics
negative:Poor sharpness for the price bracket
comment:This lens is terribly disappointing. The sharpness is well below the standard I expect for this price range. 24mm at F22 is not even useable without significant work in photoshop. It is the last Sigma lens I will own! And worst of all it cuts off the corners at 24mm without the lens hood on.

Followup Sept 09;

I've sent this lens back for warranty servicing and they refocused it. It is still substandard in sharpness and still cuts off the corners at 24mm. For a lens marketed as professional this lens makes a mockery of Sigma. I've compared the Sigma 24-70mm at 70mm to the Sony 70-400mm lens at 70mm with both lenses two stops above wide open, the supposed sweet spot for most lenses. The Sony is sharper.

compared to:Minolta 24/2.8
price paid:899
positive:Very sharp, even from f/2.8 (at the center at least). Good range and overall build quality.
HSM is nifty.
negative:Huge and heavy, but such is the way of full frame 24-70/2.8 lenses.
82mm filter threads means that each and every filter you buy costs a fortune.
comment:Bought to go with my new A900 since I couldn't afford the Zeiss 24-70/2.8. Cost being equal or even close, I would probably have gone for the Zeiss but that's the advantage of the Sigma. It's able to produce 90% of the image quality of the CZ at 60% of the cost ($900 versus $1600 USD). There's a fair amount of distortion at 24mm, more than the Minolta 24/2.8 but the light falloff at f/2.8 isn't as great in the Sigma as there is in the Minolta 24/2.8.

The build quality is good overall. The zoom ring on mine gets stiff and jerky when it gets cold (below 35 degrees). Hopefully that'll loosen up as the lens gets worked in more. The focus ring was very stiff too when the lens was just out of the box but that's been worked out with use.

I think that DarkScribe below might have gotten a bad copy. I'm very happy with mine all told.

I do plan on re-evaluating what main zoom I keep in my bag once the long hinted at Sony 24-105/4 G comes out. That's a more useful range for me and since I do mostly landscape, the f/2.8 speed isn't necessary.

positive:More compact than it's brother the 24 70mm ex dg macro. Does not extend as far when zooming. Silent and locks to focus every time. Sharp across the range.
negative:The hood is flimsy, only negative I can find.
comment:This lens does not disappoint. Locks to focus every time, quick and silent. Appears to be sharp edge to edge at all focal lengths. The build quality is superb and it is a less intimidating lens than it's brother the 24 70mm ex dg macro. When attached to the A700 balance is excellent. It is an outstanding performer all round.

positive:It is a good lens in several ways, but nowhere near as good as the previous three reviews claim. In some aspects it does not outperform a similar Tokina lens at less that a third of its cost.
negative:It often misses focus, not sharp when wide open, and colour is nowhere near as good as Minolta glass. It is a disappointing lens considering its reputation.
comment:This was definitely a disappointing lens - I had waited for it for some time and was expecting much more. I had the dealer exchange it feeling that I had a bad copy - but the same problems persisted. They took it back and I have not as yet replaced it - I am staying with my Tokina 20-35, a much less expensive lens that outperforms it. It does focus quickly and silently - when it doesn't stick - but with an A700 or an A900 that already focus quickly - it isn't really noticeably faster than the lens it replaced - the Sigma non HSM version. Perhaps on an A100 it would make a difference.

comment:Very sharp out of the box. The lens seems to focus correctly even under poor lighting conditions. The silence of the focus is a welcome change over the sonewhat noisy screw driven lenses. The focus ring clutch is fantastic as it allows one to fine tune the focus even while the lens is in AF mode.

The lens feels very solid and very well built. There are no squeaks or rattles and no wobbles anywhere. A couple of nitpicks are that the AF/MF switch feels a bit cheap compared to the CZ and the hood feels a bit lighter duty than previous Sigma hoods.

The lens is much nicer than the previous non-HSM version in that while it is slightly heavier, it is much more compact and silent. However you pay almost double for these convieniences. The image quality is about the same, if you can get a sharp copy of the non-HSM version.

I breifly tested (quick and un-scientific) this lens against the CZ 24-70, in a local shop, and the images each one produces are virtually indistinguishable. The only give away is that the CZ seems to have more neutral colors and the Sigma is a bit warmer, very slightly yellowish.

Currently, the US price of $899 is about half the cost of the CZ and therefore has an excellent price to performace ratio.

comment: I got this lens a couple days ago and have taken shots with it. I used a Zeiss in the same range that a Sony rep let me use and this lens is sharper at 70mm fractionally.I think it as good as the Zeiss under most circumstances, that is my opinion. I have a Minolta 100 F2 that is sharper than either, but that is apples and oranges.It is a steal for the price. It is sharp+ wide open and can be a joy to wring bokeh out of using DOF and big aperture. Colors are similar to the Sony 70-400 SSM, gorgeous. I will update report as I gain experience with the lens.If you look around the flickr folder , there are pics of the element and camera mount. Thanks
Here is a pic of it on the trusty A100:

Update: I think some of the other reviewers need to have their lenses looked at by Sigma. My copy still works very well.The Zeiss 24-70I originally used was returned and the 2nd copy I got to use was splendid. Ther is more chance of some reviewers getting a bad copy than the rest of us being liars. The Tamron is not more sharp than my copy, I own both lenses. I posted photos on flickr to indicate my personal experience.

Thanks,G
