The Sigma 12-24mm F4 offers impressive optical performance at the short end of its focal range, with excellent AF performance. Unfortunately, central sharpness at all focal lengths, and overall sharpness at the tele end suffers relative to its best peers.
Landscape photographers looking for a wide-angle zoom lens with exceptional sharpness and performance from 12mm-16mm.
Photographers looking for excellent performance across the entire focal range and photographers who prefer to shoot with a lighter kit.
I can think of a thousand places to use the Sigma 12-24mm f/4 DG HSM Ar lens—from the NJ Balloon Festival to the Okefenokee Swamp . Overall performance and image quality are both outstanding and the construction is top notch.
Sigma 12-24mm f/4.5-5.6 EX DG HSM shows pretty decent performance throughout the zoom range from f/8 and on. At wider apertures the lens exhibits some weakness around borders (primarily in the 12-17mm range), so you should be prepared to stop down to achieve the best results.
A huge field of view, coupled with a sensible zoom range that is still useful on cropped sensor cameras as well as the full frame that it is designed for make this lens extremely practical. A great item of award winning kit, especially if you use more than one format of sensor.
Enormous field of view, Amazing control of distortions, Solid build quality with good protection of front element
Difficult to use front mounted filters (Though not impossible), Bulbous front element needs careful handling.
While it's not the sharpest lens in the bag, the Sigma 12-24mm showed fairly decent results for sharpness. For optimal performance the lens must be stopped-down significant, to at least ƒ/8 or ƒ/11. CA is well-controlled and distortion is remarkably so.
The Sigma 12-24mm F4 DG HSM Art is a fantastic ultra-wide-angle zoom lens that significantly undercuts the price of its main rivals whilst offering almost comparable image and build quality.Image quality is excellent.
An ultra-wide angle zoom lens with minimal distortion, a constant f/4 maximum aperture and improved autofocusing.
As an architectural and real estate photographer, I was interested in getting an ultra wide lens to replace my Samyang 14mm. Main motivation was to move away from manual focus. My choice was the Canon 11-24mm L or the Sigma 12-24mm. If money wasn't an issue, perhaps I would have bought the Canon.
In my experience with this lens, the image quality is excellent. There is barrel distortion at the widest angles but this is easily correctable in post-processing. Also, this is less noticeable in many scenic photos (with no horizon line).
I love wide angles, and used to have a Sigma 10-20mm for my DX-format cameras. I recently picked up a Nikon F100 film body, and couldn't resist getting this lens. Some have commented that it's not an everyday lens, but since a 24mm prime is almost my normal lens for walking around, this 12-24mm...
Wide angle! WIDE ANGLE! 12mm simply rocks on 35mm film, there is nothing wider.
Not as fast as I'd like - 4.5 is a lot slower than 2.8 - the difference between 1/20th and 1/60th is huge when you don't have VR and can't bring a tripod...
I have owned the Nikon 14-24mm, 18-35mm, 16-35mm and Tamron 15-30mm, this lens beats them all! It is very sharp at f4 to f10 at 12-18mm but then softens a bit from 18-24mm. Distortion, CA and vignetting are all controlled very well. The lens is well built and balances on my D810 nicely.
It is a few months ago I bought this lens and the truth is that I am quite happy with it. I still didn't see its resoults on a film camera, never the less in a Digital camera it works quite well. I like at first point it's definition, contrast and saturation.
Solid building and general image quality is quite good
Specially it's f-stop and the impossibility of attaching a protection filter
I use this for architectural photography, and it's great. Very minimal distortion. It picks up flair easily, but I think that's inherent to all wide angle lenses.
Have the Sigma 10-20mm f3.5 and really like it. Decided to give this lens a try after getting the 50mm art lens and loving that. Did side by side comparisons at 12mm, 15mm, 20mm at F4 and this new lens is slightly sharper dead center BUT 5x sharper out to the edges.
I did my research and i knew what to expect from this lens and how to use it to get the best out of it. I tested it on my K-3 so far, but it is inline to be used as my rectilinear ultra wide AF Full Frame for my incoming Pentax K-1 at about 2.4x less expensive option than the newer option available.
The only zoom I own where I wish it was a prime. I use it primarly for the 12 mm. It is nice to use unnoticed, and it is fun. It is small enough to find a place in my photobag, does not have a big suncap like the Canon 17-40 L does for example. The AF on my copy is dead but i do not care.
There simple is nothing else that is that wide for a Mark II., It is not very heavy or atrract much attention., It is wide, wide, No distorting, Can be used on every sensor., Flare is well controlled.
Only useable at f11 or smaller, Color is poor in comparising with Canon L zooms. (Can be helped in post processing), Sharpness is not very good, but again, can be helped in post proccesing.
Extremely wide angle lens. If you don't want a fish-eye but want a really wide-angle lens, for the price this lens really hits the mark. Really sharp at 12mm (gets softer as you zoom in). It is heavy, but really a great versatile lens. I recommend it for sure.
