Excellent wide angle lens
16 September 2021sbcates1313

originally posted on ebay.com

I have been shooting real estate photography on an APS-C Nikon D7100 with a 16-85mm lens which has worked for most applications, but in some smaller rooms, it became a bit limiting. This 10-20mm lens solved that problem. This lens paid itself off for me in the first photoshoot with how much easier it was to get set up and capture what I needed to. Bathrooms were always a nightmare because of tight spaces, but with this lens, it's no problem at all. Being just over $200 to get the extra FoV as compared to the thousands I would spend on going to a full frame body and buying lenses to match, I'd say there's a lot of bang for buck out of this lens. The fact that it starts at f/4 is no problem in my case since pretty much all of my indoor shots are done at f/6.3 & ISO ... MoreI have been shooting real estate photography on an APS-C Nikon D7100 with a 16-85mm lens which has worked for most applications, but in some smaller rooms, it became a bit limiting.

The fact that it starts at f/4 is no problem in my case since pretty much all of my indoor shots are done at f/6.3 & ISO 640. Stopped all the way down, it's still pretty darn sharp. I'm still accustomed to having VR on my 16-85mm lens, so it's not quite as good for hand held shots, especially in darker rooms and basements, but with the much wider FoV, I have yet to run into a situation where I couldn't use a tripod. I would mention that there was white oxidation on the rubber focus and zoom rings. This is easily taken off with a dry toothbrush and doing so really brought the look of the lens back to near brand new. Other than that, everything is cosmetically and functionally in great shape.

Good photographic quality for the price

I have two of these, which I use on two different bodies (Nikon and Sigma), mainly for landscapes. Angle of view is 102.4 deg at 10mm (63.8 deg at 20mm) on a digital DX/SD frame (this lend will produce vignetting on FX), quite wide and beaten only by the Sigma 8-16 sister lens, which is 35% more expensive. Optical construction is good (3 low-dispersion elements + 3 aspherical elements). Optical performance is very good in terms of color rendition (and specifically, of chromatic aberrations). Sharpness and fall-off are good, except deep in the corners. Distortion has a rather complex pattern (turns from barrel to pincushion going from 10 to 20mm) but is tolerable overall, being mostly confined to the edges. Mechanically the lens looks cheap, as many other Sigma ... MoreI have two of these, which I use on two different bodies (Nikon and Sigma), mainly for landscapes.

This lens includes an HSM (hyper sonic motor) actuator, which allows it to auto-focus on motor-less bodies (e.g., the low cost Nikon DSLR bodies). Photographic performance is nice overall. I would spend more (+70% on average) only for the Nikon 10-24 f/3.5-4.5 . Unless your only photo subjects are resolution charts, you will not be disappointed with this lens.

Great lens!

I shoot as a semi-pro with a Canon 7D. The studio I work for does all manner of photography, from weddings/special events to real estate, fashion, school portraits, etc. I bought this lens to use for weddings, real estate, and for my own artistic work, like landscapes and urbex/architecture. I looked at the Canon as well, and for me, this was a better value. It is very sharp, and the auto-focus is quick and quiet. At 10mm, it does produce barrel distortion, but that can be fixed in post, or it can be left alone for that effect, which looks nice for certain things anyway...at 20mm, it has very little noticeable distortion.

I just did a wedding with this, ( and several other lenses, of course!) and with my external flash it performed beautifully, so for me, that speed isn't worth the extra $$$. I have also done night shoots on my tripod and gotten similarly great shots with it. I could have rated it a four for those reasons, but for WHAT IT IS, it really is an awesome lens. If you need wide and shoot on a cropped sensor, try this one!

LOVE IT!! Awesome Lens package
7 May 2022

Was looking at the Canon 10-18 mm . This is better. You get more for your money. Clear and crisp glass. I love the fact it comes standard with the case and lens hood. It was heavier than I expected for a small lens but that means it well built. Can't wait to take it out on my road trips across the country. Great price and lens

Nice extra wide angle lens for the money
1 July 2014

Over the past few months, I have encountered several situations where I needed a wider angle lens than my basic 18-55 lens. In looking at the available lenses, including reviews, this lens looked like a very good lens, in terms of "bang for the buck". I've had it for a couple of weeks now, and have used it exclusively on several walking trips. I've not been disappointed. You have to be careful with image distortion at the very wide end (typical of very wide angles). So far, I haven't experienced any serious vignetting, but I tend not to shoot with the lens wide open most of the time. It does create some interesting angle distortion, but again this is typical of the wide angle. This lens isn't quite as fast as the newer Sigma lens, but so far, I haven't found that to ... MoreOver the past few months, I have encountered several situations where I needed a wider angle lens than my basic 18-55 lens.

The lens appears to be well made, and works nicely with my Pentax camera, and at less than half the price of the comparable Pentax 12-24 lens. The autofocus speed has not been a problem, since most objects I shoot with this lens aren't moving very fast (or at all!)

Sigma 10-20mm F4-5.6 My Love!
7 April 2019

This Sigma lens is so underrated... seriously. The lens is sharp, and the focus ring.... smooth as butter! This lens eliminates my need to any other lens up to 20mm. I combine it with Metabones canon adapter speedbooster to conform my blackmagic mft sensor to almost full frame and a low-light beast! Changing the F4 of this Sigma lens to F2.4! You will not find another full frame or APSC lens that will give you that wide focal length, range, price and quality! Never!

Superb DX Wide Angle Zoom
29 March 2015

I noticed I reviewed this lens back in 2007, but since have moved entirely to FX and had given this lens to my daughter. This week, I decided to buy a new D7200 as a fun lightweight vacation camera and knew I needed to re-purchase this Sigma 10-20 f/4-5.6 lens because my daughter won't give mine back. Coupled with an older Tamron 17-50 f/2.8, these will be the only DX lenses I'll need to go with my huge selection of FX glass. There's a reason there is such a huge cult following for this Sigma 10-20 f/4-5.6 wide angle and is the reason I am re-buying it. It is just a superb example of this kind of lens. It's very sharp and fairly distortion free. It's 10mm wide end gives me that huge 100 degree field of view I love so much over the years. When used correctly, you can ... MoreI noticed I reviewed this lens back in 2007, but since have moved entirely to FX and had given this lens to my daughter.

When used correctly, you can really get in tight with foreground elements while framing the background landscape elements, producing lovely images. The glass is sharp enough to take advantage of today's 24 mp camera sensors providing you do your part. All in all, I highly recommend this lens and the fact that it's so inexpensive is an added bonus.

Superb value ultra-wide
10 September 2013

As the majority of my shooting occurs either outdoors in full daylight or from a sturdy tripod, this lens represents an outstanding value in the ultra-wide category.Autofocus speed on this revision is far more speedy and accurate than the one I had a few years ago, even in lower-light situations. This newer one does not suffer the annoying back-and-forth seek chatter that plagued the earlier one, and the motor itself is more quiet than the previous. As it is, most of my use of this lens is by manual focusing, which is plenty smooth and easy.The smoother finish is easier to keep clean, and does not seem to hold onto dust and dry skin ruboff like the previous version.As someone who does not use this lens for sports action or wildlife or motorsports shots, and ... MoreAs the majority of my shooting occurs either outdoors in full daylight or from a sturdy tripod, this lens represents an outstanding value in the ultra-wide category.Autofocus speed on this revision is far more speedy and accurate than the one I had a few years ago, even in lower-light situations.

Coupled to an EOS 50D, I have always had sharp images with good & balanced color rendition. Chromatic aberration has yet to rear its ugly head in any of my shots, while a CPL filter will do wonders for outdoors and reflective subjects.With financial circumstances forcing the sale of my previous copy of this lens some time ago, I am actually glad now to have acquired this newer one. It's simply more refined in tangible ways, and is an even better value now with current prices being what they are.If you simply MUST HAVE the "near-L" reputation of Canon's 10-22, then buy that. It's unquestionably an excellent lens. However, if you're like me and desire a great 'bang-for-buck' alternative, this one will not disappoint. Consider also that this lens is overall smaller and weighs noticeably less than Canon's 10-22, which can be considered as a feature.

Well built and excellent value lens capable of great results.
9 January 2014

I was after a wide angle lens for my Nikon D7100 and the choices for me fell primarily between the Sigma and Nikons own 12-24mm although others are available. The Sigma goes slightly wider and is cheaper than the Nikon which counters with more functionality on the Nikon body and slightly better performance in some areas. In the end, I decided to go for the Sigma and then upgrade later to the Nikon if I felt it was justified. The build quality of the Sigma is excellent. Its a weighty lens with smooth operation of all of the controls so you definitely feel you are getting your money's worth. In use, I have found the images it produces to be generally excellent. I have steered clear of using it wide open at 10mm where edges can be a little soft.

I am pleased with the Sigma, it combines a very useful wide angle view with generally good performance.
