By Algy O'connell (UK)
Its a good lens. Fairly heavy and for the first 6 months its worked quite well.



Until Just a couple of weeks ago it has started locking up. I am not able to focus or zoom in or out. Its as if the insides of it has broken. I dont feel confident to use Sigma now in the future. Which is now why I will not purchase another sigma lens again. It is cheep, but you get what you pay for.

 "Great lens for the money." 2010-07-16
By K. King (UK)
This has now become my main lens for my canon 50d. It has fantastic build quality and feels solid. I would not change it for the world BUT I do have 2 little issues that I must mention. I think these problems are a reflection of budget and I would not expect to see them on a L series lens, but then I would not expect to pay the associated price tag either!



Firstly there is some zoom-creep when the lens is angled steeply up or down. I personally do not take many photos in this way and tend to prefer either horizontal or gentle angles below or above a subject. I am not sure if this is a problem experienced by ALL users of the 24-70mm lens; if it is not then hopefully a good Sigma service may sort the issue.



Secondly mine is not quite pin-sharp at 2.8 so I tend to stop down a bit to great some truly lovely results. But again using a lens at mostly 4+ raises the question of buying such a fast lens in the first place!



I have had to list these two niggles with the lens as I think they are worth considering as a consumer. However I still really like this lens and would not hesitate in buying another Sigma in the future(probably 70-200 2.8). Well until my budget can stretch to the L series glass anyway!

 "Ok lens, looks fantastic but not quite up to specification." 2010-04-28
By Adam Jones (London)
This lens reports itself as being f2.8 across all focal lengths but in reality its really not. Fully open at 2.8 my images have often suffered from terrible vignetting, really not at all subtle but really quite drastic darkening covering most of the image with huge great black corners.



Also the lens barrel on mine (maybe not others?) falls forwards, rolling from 70mm to 24mm whenever the camera is facing downwards with the lens barrel at the ground. This surely shouldn't happen! It should have enough grip to hold its focal length! I have a feeling that this issue has worsened since using.



Also I got some dirt particles inside the elements of mine within the first month of use. I've tried to keep it as clean as possible although have been on a fairly hectic 5 week trip with the camera and lens always together in a camera bag. There are quite big gaps between the barrel elements so its easy to see how this could happen.



Its a real shame as the lens looks at first sight to be really quite good quality. Its big, heavy and aesthetically very pleasing but upon finer inspection mine fails to meet the grade. Sure its a lot cheaper than any canon lens but its not actually that cheap an item so annoyed its not better.

 "Pretty good considering" 2010-03-29
By Malcolm H. Smith (London, England)
I recently bought this lens for my Canon 5D as a walk around lens and for using on my upcoming trip to Africa. I would have liked to have gone for the L series canon made lens but I couldn't really afford it so I opted for this one instead. On a test shoot I was very surprised with the image quality especially on close up shots and the sharpness is pretty good as long as your shooting about f8 or higher which with the iso quality in the 5D isn't a problem for me.

The auto focus is a bit slow especially focusing from one extreme to the other and I have to say the lens hood provided is pretty useless and in bright light gives no protection from lens flare so be prepared to make one yourself out of bog roll if bright lights are your chosen subject.

I love the matt black finish and also the weight which in my opinion gives more stability when shooting but thats just my personal preference.

All in all pretty damn good considering you would be paying over £600 for an L series of the same focal length.

 "Good value robust lense" 2010-03-19
By Robert Derry
I have owned this lense since 2006, originaly it purchased it to replace the 18-55 that came with my 350D. The 350D has been replaced with a 7D now. I find the Sigma lens to be of very good build and image quality. I use this lense for about 90% of my photograpy form landscapes , close ups using extension tubes to snapshots. I have used it in climates from Arizona deserts in high Summer +40C to minus 23C Idaho mountain Winters and anything the British weather can throw at it.I found the auto focus stops working at around -10C and after -15C it give up the game all togeather but was still OK after it has thawed out. This is a robust lense as it still works despite it not having an easy "pampered" life. The only niggle I have is the satin black coating on the lens body gets dirty/dusty and is hard to clean.

I Have use this lens with a ring flash after I got a 82 -77 MM stepdown ring and still get good results. Overall I am very happy with it as it has served me well. Focus could be a little quicker and it gets confused by close up twigs and grass when taking landscape shots. If/when it stops working I will replace it with another Sigma 24-70 F2.8 I can offer no higher praise than that.

 "Very Good lens, but it has a slight problem" 2010-02-15
By Richard Smith (Hull UK)
For the money this lens was excellent, however the one problem i have with it is when i switch from Macro to Normal telephoto it gets a bit "Sticky" until i zoom in and out once or twice, I am not sure whether it's a fault on mine, or with the product in general, so i am docking one star! The delivery was FIRST CLASS, it was here in 3 days all the way from the US, and came with a box full of extra cleaning goodies free of charge! brilliant! I was unsure about getting a Sigma lens, as they have a bit of a stigma, not being as good as the Cannon ones, but for the price I think its a great product!

This zoom lens is solidly constructed and has a smooth action.



It's macro function is a useful extra but be aware that it operates from 0.95m away at the closest! So you get ultra close up zoomed in on objects that are at least 0.95m from you, takes getting use to.



Obviously without anti-shake and with a small f stop range it does suffer from problems of shake in low light unless you use a high speed virtual iso rating.



Well worth its low cost.



Be aware that this product is shipped from New York and the way they ship it, import duty wise, strikes me as slightly odd. You don't pay any extra to the quoted price but I wonder if that is all as it should be?

 "Very good telephoto lens" 2009-08-05
By Richie Cunningham (all around it depends on the weather)
Like most people looking at this lens I had a choice between the canon 75-300 and this sigma lens. I the macro feature was selling point. It's not a great a macro but having it is always a bonus. At first I was apprehensive about using the lens during the low light since the focal factor is small and I was worried about the weight. But it' is a telephoto lens and It's expected to be heavy.



I used the lens to cover the london triathlon which invovled lots of running around and taking allot of action shots. The lens was great for both the photo quality and weight.After basically holding it up for an entire day it still felt fine. The only drawback was shots at low light but this involves the camera to much steadier , this can be resolved using a standard SLR tripod that supports telephoto lenses.



This is a great lenses for the more serious hobbyists like myself who don't want to invest an much more expensive telephoto lenses.

this really is an absolutely amazing lens. i bought this recently, and i was absolutely blown away by the quality and sheer beauty of the lens and the photos it can take. the auto focus is great, and with a good camera, it can be a truly wonderful experience to use. i highly recommend this lens to anyone, beginner or semi pro. it is absolutely fantastic. I also found the macro setting very useful- it can take some stunning photos, but you need to be careful that you have something steady to rest the camera on, or a tripod, or even a really steady hand, because close ups when your hands are shaking can result in serious blur. fantastic lens.

 "Superb Quality" 2010-06-24
By P. Jenkinson (Manchester)
This lens is just brilliant. The clarity of the produced images is superb.

It can sometimes be difficult when using it hand-held, but once you figure out the settings, you will be producing excellent results.

I found that setting my 450D to fully automatic often produced images with very shallow depth of field, so now I use Ap priorty and set the aperture to around F8 ro F10.

The macro capabilities are far better than I had hoped, and this lens should be a part of any photographers kit.

 "Good starter macro lens" 2010-03-05
By Darren Simons (Middlesex, United Kingdom)

I bought this macro lens as I wanted to do some basic macro photography using a full-size sensor.. Firstly I can definitely recommend that 100mm focal length is ideal for starting at macro - 50mm is just too wide (probably more use for portraits) and 150mm is just too expensive.



This Sigma lens is solidly built and certainly doesn't feel plastic at all - it's part of the EX range which are the top tier of Sigma lenses (easy to spot by having a gold ring at the end of the lens). Focussing is sharp and as a keen amateur I certainly can't see any shortcomings in this lens in terms of quality (f2.8 is certainly wide enough for me as even at that aperture I can throw the sharpness on macro shots very easily - I actually found I was using f4 most the time as the sharpness was falling off too quickly so focus has to be spot on)



There are a few things I don't really like about this lens though. The auto-focus is quite slow (especially when compared to the USM Canon equivalent, albeit quite a bit more expensive), and the collar which is used to select auto or manual focus is quite clumsy and just doesn't feel right. That said for most pure macro work you're best off using the manual mode and once in that setting the control is pretty good.



My other complaint is that if you put a UV filter on you can't put the cap on - this is because the cap fits the inside of the front of the lens in a slightly different way to most lenses... easily rectified with either not using the UV filter (which is fine since the front of the glass is set a long way back from the front of the lens so is difficult to damage) or buying a suitable cap (prob £10).
