 "Lovely lens" 2010-07-13
By JFL
I bought this because I love shallow dof for some shots and my canon 50mmm was a bit too long for indoor shots on my 40d. I don't like buying non Canon lenses but this was well reviewed so I gave it a go and I'm happy that I did.

 "One in a Million - Literally Speaking" 2010-07-12
By L. Lee (UK)
Bought this from Amazon recently, was really impressed with the quality of the build on the lens, real solid hefty piece of kit yet small enough for me to carry around!

Was testing this out on my new Canon 550D, the video recording on it was absolutely amazing! Crisp quality! Would definitely recommend this to anyone!



The f/1.4 was a real joy to play with and i was thoroughly satisfied with it, the sharpness of my pictures and the background blur was a nice touch which added more emphasis to the subject in focus.



Until i took a couple more shots, and realised the focus appeared to be slightly to be off.



Prior to purchasing this lens, i'd read about the lens having alot of front/back focusing issues, so i wasn't too surprised, but was abit disappointed.

Didn't realise until i tried focusing on certain points, taking picture and upon closer inspection of the image, i'd find that the point of where i intended to focused on, was off by quite a margin. Although slightly disheartened, i am not going to give up trying to find the 'perfect' working model of this lens.



A word of advice, though not guaranteed - check the serial number on your lens/box. Supposedly later batches of the item was less likely to have problems.



A word of recommendation, get the B + W 62mm UV Filter with Multi-Resistant Coating, cheap solution to protect your lens and give you a nicer picture!



Goodluck & Enjoy!

 "Superb, but AF can be difficult" 2010-06-22
By Neil Bailey (uk)
This is a superb lens, and the 30mm (48mm equivalent)focal length is perfect for portraits in low light, where flash would be intrusive. The only problem, as other reviewers have stated is in respect of Auto Focus (AF) in poor light/full aperture shots, but this is inevitable. Overall the build quality and performance are superb, and I recommend the lens without hesitation.

 "Fantastic lens" 2010-06-07
By I. Ahmad (London, London United Kingdom)
I own a Canon 40D with the following lenses Canon EFS 17-85mm USM IS, Canon 50mm MK 2 and Sigma 10-20mm EX DG. The majority of pictures are taken with the Canon 50mm which I bought very cheaply 2 years ago. I do a lot of portraiture shots and the canon 50mm works pretty well for the most part especially for head shots. However for full length body shots you need to be standing a fair way back. I saw a gap in my lense collection. I thought if i had a slightly wider angle prime lens then I could take more interesteing full length portraits so I decided to buy a the Sigma 30mm to fill this gap.



I have only had it for the weekend but have already taken a couple of hundred shots and I'm incredibly impressed by the results. The colours are vived and the sharpness of the pictures are better than any of the other lenses I have. Sigma include the a lens hood when purchasing the lens. Why don't Canon do the same ?? Instead they charge upto £30 for a bit of plastic - be sure to factor this into the price when considering a lens. Don't be fooled by third party lens hoods that may not fit your lens correctly.



The build quality has a sturdy feel and the focus ring is well positioned with a nice grip for manual focussing. Moreover The hypesonic motor ensures auto focussing is fast so you don't miss the important shots.



In summary this is an excellent lens but it obviously costs over 3 times as much as the canon 50mm however you can see results in pictures. If you have the money it's worth the investment for the pro-sumer who doesn't necessarily want to fork out for a Canon L series Lens.

 "Sell that kit lens and treat yourself, it's worth the investment" 2010-04-29
By R. Hinchcliffe (Yorkshire)
I got the Sigma 30mm f/1.4 lens to use an an 'everyday' lens to go with my new 550D. This is an excellent lens for the money (I paid £270 for it). After mainly using a Canon 50mm f/1.8 (which is an excellent lens for £60!) on my 400D for the last couple of years but commonly feeling the need for a slightly wider angle, I really wanted another fast prime lens, and I read a lot of good things about the Sigma - all of which have so far shown true. Compared to the Canon 50mm f/1.8, the Sigma 30mm is much, much more solid lens and 'feels' like a better product. The sharpness is spot on (i'm sure some Canon L lenses are way better, but who really looks at photos zoomed in at 100% anyway) and the f/1.4 has come in very handy. I was unsure whether to get this lens or something like the Tamron 17-50mm f/2.8 for it's zoom range - but I'm glad I got this little Sigma prime. I imagine it'll be on my camera 90% of the time and so far it's focusing and build quality have blown me away. The weight of the 550D + Sigma 30mm makes for a good solid SLR camera to carry around all day.



I use it on the 550D, and for those who are interested - it works just as well as a lens for shooting video. The manual focus ring is large, comfy and easy to turn which makes shooting even a moving subject with a shallow depth-of-field easy.



All in all I can't recommend this lens enough. If you're looking for a lens to leave on your camera 90% of the time this is definitely a good option. Sure you don't get the zoom range of the canon's kit lens but 30mm on a crop body is a very good compromise for most peoples shooting styles. I promise you won't miss that zoom, and the f/1.4, fast quiet focusing and excellent manual focus make up for any zoom envy you might get.

 "A great upgrade." 2009-12-05
By N. Clarke
Excellent lens for money paid, this lens arrived in great condition and in full working order with no marks or imperfections to the glass. I bought this lens as an upgrade to the standard 18-55mm lens on my Canon 450d and I have been very pleased with it so far. The autofocus is accurate and the pictures are noticably a lot clearer than the canon kit lens. The autofocus is slightly noisy in comparission to the kit lens but as it is not used for wildlife photography this isnt really an issue that would put you off buying it.

 "Seems great so far" 2009-12-04
By Mr. A. J. L. Carter (UK)
I bought this for my girlfriend to replace her aweful old canon pre digital slr lens, so to be honest anything is an improvement! I use nikon and its the first time I have actually taken an interest in her camera as a result!. Seems to handle low light situations very well with the OS and 2.8 aperture. Colour rendition and sharpness seem very good too, and i particularly like that the lens does not extend, so avoids lens creep - a problem with many sigma lenses. Its lightweight too, with a slightly plasticy body, but this is no complaint, it feel robust.

 "Fast walk around zoom for cropped SLRs" 2009-06-07
By M. G. A. Kerby (Manchester, UK)
Sigma 18-50mm f2.8 EX DC Macro Digital Zoom Lens For Canon Mount



For about 6 months I used a Canon 17-40mm f/4 L series lens and decided I wanted a faster lens. The 17-40L is fantastic; all I needed for most outdoor shots, very wide and of course usable on full frame/35mm Canon SLRs. However, it was f/4 and I wanted an f/2.8 like my telephoto lenses to allow me to use it in churches/houses with less need for higher ISOs and flash.



My options were the Canon 16-35 f/2.8 L II, which is very very expensive, but of similar build quality to my 17-40L. I couldn't justify the ridiculous price tag, especially seeing as I was using a cropped sensor camera. My other considerations were the Tamron 17-50 f/2.8, which I found too plasticy, though very similar in shape/external design and the Tokina 16-50mm f/2.8 which I opted against.



The Sigma 18-50 is very good; coming with a lens case, lens hood and both caps needed, all I needed to buy extra was a UV filter. It has been given the EX finish label, which I sort of disagree with even though it is fairly heavy and well built it is not anywhere near as well built as my Sigma 70-200mm f/2.8 which is also an EX lens. Anyway here's a list of pro's and con's to weigh up:



Pros

- Constant f/2.8 aperture: This is very useful indoors and to an extent for shallow DOF work

- Close focusing distance allowing for 1:3 macro focusing (useful for flower photographs and close up portraits)

- Smooth zoom and focusing rings

- Fast auto-focus

- Fairly decent build quality, certainly better than the Canon kit lenses and the Tamron 17-50mm lens.

- Non-rotating front element (good for filters)

- Zoom lock: good to stop the lens from creeping in zoom

- Accurate auto-focus, good keeper rate

- Very nice lens cap - the new Sigma lens caps are easy to remove with the hood on



Cons

- Lens extends while zooming becoming largest at 50mm

- Noisy autofocus compared to HSM (or USM)

- Not upto most Sigma EX lenses build quality, this could be because its not a DG lens

- No focusing window, although I rarely use that on other lenses to be honest.



Verdict:



This lens is very good. After having it for a few months I've gotten used to it and took some good photos with it. Its auto-focus is very accurate and I find that important in a lens today. I recommend it for anyone with a 1.6x crop sensor: 350D, 400D, 450D, 500D, 1000D, 20D, 30D, 40D, 50D

 "Versitile lens" 2009-06-04
By D. McFarlane (Yorkshire, UK)
I've had this lens for a short while now and have taken it out on a few trips. Essentially this represents a faster version of the standard kit lens that I got with my 20D, so it's a reasonable general purpose lens for day-to-day use.



I found that it took a bit of getting used to this lens to finesse the focus and get sharpness into my photos. It can be a bit soft wide open, but normally I have no complaints.



Essentially paying this sort of price for a constant 2.8 lens with some Macro functionality you can't really complain. Construction has a solid feel to it and, as usual, Sigma supply you with a hood and, indeed a lens carry case as part of the deal.

 "The clear choice." 2008-06-01
By R. C. Cooper (Liverpool UK)
I bought this lens from the auction site about 6 months ago.



The one thing this lens made me realise was how poor the kit lens that came with my Canon EOS 300D actually was. And I had never had any complaints about that lens whilst using it.



The results from this lens are razor sharp and the colours are superior. The difference in results from upgrading to this lens where what I was expecting from upgrading to a new camera.



Beware though, it is very heavy and seems prone to ugly green lens flare when taking shots with the sun in view (even with the hood) but other than that I can't recommend it enough. I am now saving for the Sigma 10-20mm rather than the EOS 40D because I've realised its best to invest in glassware.

 "Brilliant lens" 2008-02-11
By Don Pelayo (Asturias)
This is a very good value for money lens , for less than half the price of the canon equivalent this lens performs as well ( and some argue than performs even better ).



It weights nearly half a kilo but is well balanced and feels strong in the camera. The EX DC range of sigma is similar to the L IS in canon for more image sharpness.



This is a lens that ,along with a good telephoto 80-200 ,will complete most amateur photographers kit.



I take 80 % of my pictures with this lens, is great for portraits ,landscape and interior shots.

 "Problems with the 350D" 2010-05-29
By E. Glen (Glasgow,UK)
If you have a 350D do not buy this lens, because you will have focussing problems. It seems to work fine with subsequent models, according to the other reviews. The Optical Stabiliser wouldn't function properly on the first lens that I bought. Focussing on its replacement was hit-and-miss, very frustrating. The retailer checked out my camera which was fine, and sent the lens to Sigma for a check - Sigma claimed that there was nothing wrong with it but,significantly, asked which Canon camera was being used. I had to sell it at a considerable loss.

The Photozone website uses a 350D for many of its assessments, and did not rate the quality of this lens very highly. Unfortunately, I hadn't read it until after I'd purchased it!

 "Don't buy this lens." 2010-01-28

Don't buy this lens.

It weighs a tonne.

 "A good all-round lens but remember the compromises" 2009-10-06
By R. Miller (Somerset, UK)
An internet search reveals various specialist reviews that'll either rate this lens as ahead of the equivalent camera manufacturers' lenses or slightly behind them in terms of quality. That's an ambivalence that points to pretty good glass and at a price which is significantly less than the camera brand-name - the product almost sells itself.



I've had this lens about 8 months now and it's probably on my Nikon D80 about 60% of the time. It's a great all-round lens and in my view its quality is easily as good as the first-generation equivalent Nikkor (I don't know about the latest Nikkor version). It's well built (maybe even a little heavy) and exudes quality. The internal motor is virtually silent and the optical stabilisation only makes itself known by the little clicks you hear as the gyroscopes kick in - and make no mistake about it, the stabilisation works! I was a little sceptical of its efficacy when I got the camera as it was so quiet, I wondered if I had a faulty model, however after a half-hour testing it at various focal lengths, apertures and shutter speeds and comparing the results with the OS switched on and off, it became readily apparent that it does significantly help at those longer focal lengths and/or longer exposures.



For all that, you have to bear in mind the compromises involved in building a lens with this range. It's like the proverbial "jack-of-all-trades-master-of-none". It does most things pretty well without being outstanding at anything. It can be a little soft wide open and it's not a fast lens (although the OS helps), and if you like soft, creamy bokeh this is not going to deliver.



Having said all that.........would I buy another? Definitely! It's a great all-rounder and has come into it's own when I've been on overseas trips where it's impractical or ill-advised to take anything more than the bare minimum of kit. It's a great walk-about lens too. Whack it on the camera and you've got a lens that will deal with the vast majority of photographic challenges.

 "Superb multi function budget lens" 2009-08-24
By Don Pelayo (Asturias)
This is a Superb multi-function budget lens covering a wide focus range and incorporating a very useful optical stabiliser ( a must when using it towards the narrow end in low light or fast moving objects )



The proce is right for a starter lens ( those who buy only the body of D-SLR ) and better value for money than a kit lens.



The biuld is execellent and feels solid and well balanced , it takes a 72 mm filter.

 "Good walkabout lense" 2009-08-22
By Mr. L. D. Greenhow (UK)
After reading all the other reviews i went ahead and purchased this lens and Im not sorry. Bought it primarily for a family holiday to Disney so that I only had to take one lens and have just got the pictures back and they are great. But the lens is a little soft for the serious photographer. But an excellent travel lens it hasn't left my Nikon D40x since.
