The Sigma 50mm F1.4 DG HSM | Art is distinctly large, heavy and expensive for its type. However this is more than made up for by its fast silent autofocus, solid build quality, and absolutely outstanding optics.

• +

  Stunning image quality - super sharp, minimal CA and practically no distortion, Impressive flare resistance, Generally attractive rendition of out-of-focus backgrounds, Fast, silent, and accurate autofocus, Excellent build quality

• -

  Large and heavy for a 50mm F1.4 prime, Relatively expensive for its class, No weather sealing

The Sigma 50mm F1.4 DG HSM doesn't quite achieve the optical perfection of the $4,000 Zeiss Otus, but it gets close at a quarter of the price.

• +

  Extremely sharp. Minimal distortion. 15.7-inch close focus. Available for several camera systems.

• -

  Big. Depth of field scale isn't that useful. No optical stabilization. A little pricey.

There have not been many Sigma lens announcements that generated the anticipation that the Sigma 50mm f/1.4 DG HSM Art Lens announcement generated. The 50 Art Lens was announced not long after the Zeiss Otus 55mm f/1.4 Distagon T* ZE Lens arrived, delivering a not-before-seen high level of...

Similar to the excellent Sigma 35mm f/1.4 Art that I have numerously praised here at Photography Life in the past, the Sigma 50mm f/1.4 Art definitely deserves the high praises. Unlike its predecessor thatfell short in a number of wayswhen I put it against other 50mm primes, the new Sigma 50mm...

Overall, the Sigma 50mm/1.4 is a great lens. The bokeh is soft yet complex; the clarity in details is picked up without losing blur; and the vignetting on the edges is not an issue when shooting wide open.

My biggest disappointment is very inconsistent AF performance - same picture taken twice from the same position - one is in perfect focus, second is completely soft. Huge vignetting at f/1.4. My first and last attempt buying third party lens. Nothing compare to Canon 50 f/1.2.

Sigma has added to their 'Art' range of fast aperture lenses with this new 50mm f/1.4 lens, which will be available to fit Canon, Nikon, Sony and Sigma SLR cameras. This lens costs around £850, which seems like an awful lot for a 50mm f/1.4 lens.

Back when we originally tested the Sigma 35mm f/1.4 DG AF lens , the first in Sigma’s new high-end Art series to be released, we weren’t just impressed, we were eager to see what would come next.

Although zoom lenses are certainly versatile and convenient, they do have some drawbacks, including relatively small maximum apertures.

I had and used this lens for less then 6 months before I started noticing that my shots weren't in focus. This lens is seasonal for me as I primarily shoot portraits/ Lifestyle during the summer, so the lens wasn't used often. My first shoot was amazing! Second amazing!

The lens is good but be careful, it may not come with warranty from Sigma. When I purchased it says is new but when I register the warranty with Sigma it says that lens is 3 years old and 9 month so no warranty for with this product. Not sure what kind of warranty has with Overstock.

I had high hopes for this lens after purchasing the 35 f/1.4, which has been consistently fantastic. Out of the box this lens was a huge disappointment with the autofocus substantially off. Since I had the USB adapter for the 35 I plugged this lens in and made some adjustments.

Focusing speed is excellent in low light. I have used it for 2 weddings and I'm very happy with its overall sharpness even with the lens wide open at f/1.4. Focus accuracy is also excellent. Its a great convenience to have a lens cap size of 77mm similar to all my other lenses.

Just received this Lens today at Christmas eve and believe me this lens is the best lens so far I have experienced so far. Without this lens any full camera is not complete.
