Sigma 311101 50mm F1.4 DG HSM Art Lens for Canon, Black

Product Information

Sigma also clarifies that any DC lenses where the image circle is made to match APS-C sensors is used, the EOS R won't automatically switch to its built-in 1.6x crop shooting mode, meaning it will have to be set manually. A future firmware update, expected to be 'announced at a later date,' will make this switch automatic and add support for the EOS R's Scene Intelligent Auto mode.

The 50mm f/1.4 DG HSM Art lens is designed for the working professional. Or it’s for the advanced enthusiast who wants a fast prime lens and is willing to pay for quality at the cost of convenience. (This is a large, heavy lens for a 50mm.) Of course, lens design has moved on leaps and bounds since this 1960s example, and the latest Sigma offering, the Sigma 50mm f/1.4 DG HSM | A, shows just how far things have come. Sigma notes when Digital Lens Optimizer, located within the EOS R settings menu, is switched to 'OFF' but peripheral illumination correction, chromatic aberration correction and distortion correction are turned on, those corrections will be made for each lens, specific to their optical characteristics. 'This is applicable to DG and DC lenses from Contemporary, Art and Sports line listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later,' says Sigma in the press release.

Comments

I compared my Sigma directly to my Nikon 50/1.4G and my Micro-NIKKOR 55mm f/2.8 AF on the test range at infinity. The lens has a certain plastic feeling. But overall, it’s a durable lens. The handling of this glass is pretty good. The rubber elements, like the focusing ring and the grip, provide a steady hold. Generally speaking, the Sigma 50mm f/1.4 DG HSM brings reasonable resolving power. So it won’t break even under the pressure of a high-megapixel sensor. If all you care about is the best possible optical quality for the next several years, then by all means this Sigma lens is superbly sharp, focuses extremely fast and has no visible distortion. If you don't worry about long-term as I do, this Sigma lens is fantastic.

In this box sits the case with the lens and hood inside. The case is the padding - there is no foam. Flare blob, full solar disc, 02 September 2014.

The taller the column, the better the lens performance. Simple.

Even with all this glass, there is but one very dim blue blob, and it's only visible under the most contrived conditions thusly: It tips the scales at 1.8 lb (815 g). And it measures 3.9 inches (99.9 mm) in length. So the casual hobbyist might find it a bit too much lens to carry around. For comparison, the Canon EF 50mm f/1.4 USM weighs only 0.6 lb (290 g). So this lens might not be the ideal choice for travel photography. Key Features The Sigma 50mm f/1.4 DG HSM features Sigma’s HSM (Hyper Sonic Motor) autofocus (AF) technology. This has an internal focus. So it’s pretty quiet. (As one would expect from a higher-end lens like this.)

Google Pixel 7a Review – new budget phone king

The Sigma 50mm f/1.4 DG HSM Art is a lens that delivers outstanding performance at a reasonable price. This Sigma prime lens won the EISA Award for the Best Product Category in 2015. And after all that time, it still holds its place among the best lenses on the market. Falloff of illumination towards the corners of the frame is fairly typical for a lens of this focal length and maximum aperture. At f/1.4 the corners are 2.17 stops darker than the image centre and visually uniform illumination is achieved with the aperture stopped down to f/4 or beyond. The Sigma 50mm f/1.4 DG HSM Art lens delivers what it promises. It’s great quality for the price. But it is not cheap. Still, if you’re looking for the best-value lens, this is better than similar top-of-the-line lenses. (Ones from original camera manufacturers.)

Believe it or not, the autofocus speed can also be improved. Sigma told us that with most lenses the speed of the autofocus motor inside a lens is actually restricted slightly. This is to aid AF acquisition by giving the system slightly more time, and to ensure that continuous focusing is smoother and less jittery, particularly when shooting video. However, if you want to get faster single AF performance, increasing the motor speed is now an option. I didn’t notice any barrel or pincushion distortion with the 50mm f/1.4 DG HSM at any aperture, as expected from a 50mm lens. This is usually the nature of using a nifty-fifty. It will result in close to an invisible error in perspective.The Sigma 50mm f/1.4 is astoundingly sharp at every setting. You just need to be sure it's in focus and that nothing moves. If you think you want one of these Sigmas, or want the sharpest possible 50mm lens for your DSLR, you'll love it. Its optics really are as good as you've heard.
