A perfectly adequate and very versatile lens at a very reasonable price. It will produce images suitable for all but the biggest enlargements, or most demanding uses. For anyone with a very high-res sensor that is looking for ultimate image quality a better choice is the new 18-35 from Sigma ...

Sharp enough and with sufficient resolution for most purposes Optical stabilisation Useful focal length range Macro capability Very high image quality across the frame is attainable at moderate FLs when stopped down Pretty well put together from high quality materials

Corner sharpness significantly different from edge; Needs to be stopped down to make full use of the image sensor; Significant CA (purple and green fringing) at wider focal lengths; Not weather-sealed

I ordered this lens with the Sigma USB dock due to worrying about the focus being out of calibration after reading forums talking about this. As it turns out there was no need to worry at all. Focus is spot on on a Nikon D750 SLR body.

Consistent Output; Durable; Quick Focus; Sharp Focus; Strong Construction

Not weather sealed

I have had a lot of lenses, and with time, I just keep 3 for my D800: One of those is this Sigma 24/1,4. The two others are the new Nikon 300/4 and the traditional Nikon 105 macro, but with this 24 art, sigma is to my point of view at the same level as Nikon, and much less expensive.

I bought this lens 2 months ago and have 3 other wide angle lenses that rate in the top of all reviews . The sigma 24mm f1.4 art is the best lens ive ever owned its so so sharp I have not even used the docking station that I own because its sharper than anything simply amazing hands down it deserves...

: Sony's A99 has the best high ISO ability of the three cameras here. It's a no brainer for event photographers.

Sigma's Art range of prime lenses is among the most sought after on the market. Not only do they offer good value for money, they also display stunning optics and excellent design. The 24mm, which works on full-frame or crop sensor Nikons, Canons and now Sonys, features 15 elements in 11 groups.

Want to get photographers' attention Put "f/1.4" in the model name of your lens. Pair that extreme wide aperture with a highly useful 24mm focal length, arguably best-available 24mm image quality and an attractive, highly functional design and you have a lens destined for success.

Sigma keeps on rolling out more "Art" (professional grade) series lenses - obviously with quite some success as you can also conclude from our previous reviews of Sigma Art lenses. Slowly but steadily Sigma has gained quite a reputation in the professional community as well.

Sigma continue to aggressively fill out their Art, Contemporary and Sports lens ranges, and the new 28mm F1.4 DG HSM is the latest optic to join the well-renowned Art family, slotting in between the existing 24mm and 35mm models.

Sigma 28mm F1.4 DG HSM A is a Fixed aperture Auto Focus (AF) Wideangle Prime lens with 35mm FF max sensor coverage, and it is designed to be used with F(FX) Mount cameras. What type of photography is the Sigma 28mm F1.4 DG HSM A lens good for?
