Sigma12-24mm f/4.5-5.6 EX DG IF HSM Aspherical Ultra Wide Angle Zoom Lens for Nikon SLR Cameras

Purchased this a little over a year ago. The only dissapointing thing was unlike the advertised picture this lens did NOT have the little auto/manual focus cut out switch (Nikon mount). I would love to have it on this lens but I have learned to work around that little shortfall.This lens is wonderful for capturing large vehicles up close (less than 15' away) such as Fire engines or trains. This lens enjoys lots of light. it will do a decent job in poor lighting but it really excells in brightly lit scenes. Focus time using a Nikon D5000 is quick in good lighting. There is however a significant amount of limit to limit "hunting" when shooting in Dusk/dawn situations in the shadows. The Nikon D5100 minimizes the hunting around with this lens and can usually focus quickly and spot on in poor lighting. I have found that using single point instead of wide area greatly reduces the hunting around with this lens on either camera.It is wonderful for getting pictures of huge subjects (tall buildings, cranes or large panoramics that capture everything high low and wide. It is easy to carry around and is a good lens to have in the bag. A lot of times i use this as my prime when documenting emergency scenes as it captures the big picture.Solid feel and have probably used it for over 1000 shots. Glad I got it when i did. I would have gone 5 stars if the switch was on the lens.

Works great on my D750 Nikon

This was better than described. Excellent value we will continue to buy from seller. He even included the original box, the lens case and paperwork.We have used it numerous times and it is in perfect working condition. No scratches or wear and tear at all.

This one led lens doesn’t work in live mode!

Good quality lens

I got it because I intend to use it on both my film and my digital bodies. For ultra wide angles I'll use it with film (Nikon N-80) and for more conventional wide angle with my Nikon D-200. It's one of three lenses I'm taking with me on vacation to the mountain states. The others are a Nikkor 28mm - 85mm and a Nikkor 70mm - 300mm with 2X Tamron SP doubler. Since I don't yet have photoshop or similar I wanted to be able to take real wide shots without having to paste them together.

Awesome lens but can't use filters

As always, when buying third party lenses there is an element of doubt regarding the quality of the lens itself. The fact that third party lenses are also very competitively priced sometimes adds to the confusion as we all like to believe, "you get what you pay for". This Sigma lens however, ended up surprising me and quelling all my doubts.Apart from the fact that this lens is the widest rectilinear lens currently available, it is also an amazingly sharp and well-built lens. The HSM motor is very quiet and quick and even focuses in low light. Despite the fact that the lens is large(ish) it's actually pretty light and isn't a chore to carry along and use all day.Now, compared to the Nikon, this lens does have some compromises, namely it's speed (F/2.8 vs. F/4.0-5.6) and of course the Nikon is supposedly weather-sealed as well. But unless you intend to use this lens for astro-photography, the speed of this lens is a non-issue. I've used this lens on many travels to Peru and Ladakh(J&K, India) and have also used it extensively to shoot in NYC, not once has the aperture ever been an issue as I always tend to stop down. However, even wide open the lens is decently sharp and stopping down only makes it better.One of the most stunning aspects of this lens, is that it barely exhibits any distortion whatsoever! I was truly amazed to see this as it's very atypical for a wide angle lens. However, it does vignette significantly on FF cameras, but this is easily corrected in post. The lens also doesn't exhibit any CA.Overall, I'd recommend this lens very highly, especially over the V2, which seems to have more distortion. For the price you pay, this is a no-brainer over the Nikon lens.

I use this lens both professionally and for fun and am very impressed with it. It is excellent for interior shots as long as you are aware of converging/diverging angles, and you can get very creative with it outdoors. It is a fairly weighty and bulky lens but easy to use. I have no hesitation in recommending this lens, especially for the money.

I am really enjoying using this lens. It is really good quality and the images are crisp. Had very good customer service. Would really recommend this lens and supplier.

I was worried about getting a sigma lens as my Nikon lenses are very good. However, I am really impressed with the quality and I have taken some great pictures.

Everything very professional. Product as it was described and fast delivery. Recommended.

Amazing ultra ultra wide lens would prefer if it was f/2.8 or better like f/1.2 but beggers vannot be choosers
