Sigma’s 50mm f/1.4 DG DN Artwork takes its place as the newest lens in Sigma’s venerable high-end lens line and is a welcome addition due to glorious efficiency and a low value of entry. Sigma’s Artwork lenses are the corporate’s high-end lens sequence, designed to offer glorious optical traits and very good rendering. The Artwork lenses are sometimes cheaper than the high-end choices from the digicam producers, though usually with some compromises in comparison with the producer lenses. Usually, Sigma’s Artwork lenses focus extra slowly and fewer precisely than the competing producer lens, they usually’re usually bigger and heavier than the comparable manufacturer-designed lenses. The value of Sigma’s high-end glass is usually as a lot as half the worth of the producer lenses, and plenty of critiques of those lenses embrace sentences like “you get 80 % of the efficiency of such-and-such lens for half the price.” Sigma’s new 50mm f/1.4 DG DN Artwork lens ups the ante with a lens that’s now nearer to the efficiency of anything in the marketplace than earlier Artwork lenses due to the brand new Excessive-response Linear Actuator (HLA) system that the corporate says improves the pace and monitoring whereas working almost silently.
Sigma 50mm f/1.4 DG DN Artwork: Pushed Inside Historically Sigma (and different third-party lens producers) use rotational motors of some sort, a design that was created and optimized for DSLR lens operation. You’ll be able to consider a rotational motor just like the drivetrain on a automotive: it’s simple to hurry up a automotive or sluggish it down, however altering path from ahead to reverse requires coming to a whole cease after which altering the path wherein the gears are shifting. A linear focusing system is similar as a magnetic levitation practice. In it, an electrical present pushes a sled suspended by a magnetic present above a rail. The sled present is utilized to maneuver, and the sled strikes in a single path. The present is reversed to alter the sled’s path, and the sled is pushed the opposite method. No shifting elements imply no friction to decelerate the method and no bodily gears to reverse. The shortage of shifting elements additionally leads to smaller lens designs as a result of this sort of motor is way smaller than a rotational one. It additionally reduces or eliminates the operational noise.
Till there’s a brand new Sony lens at this identical focal size and aperture outfitted with its quickest linear motors, there’s no telling how the Sigma HLA motors carry out in comparison with Sony’s system. Nonetheless, at the moment, it outperforms my take a look at Sony 50mm f/1.4 Planar Zeiss-designed lens. Optically, the lens is comprised of 14 parts in 11 teams, together with one SLD (Tremendous Low Dispersion) and three aspherical lenses. An 11-blade rounded aperture creates an extremely delicate bokeh that’s an indicator of Sigma’s Artwork lenses. The glass has Sigma’s Tremendous Multi-Layer Coating to cut back flaring and ghosting and a front-element coating to cut back fingerprints, grease, and dirt contamination. Sigma 50mm f/1.4 DG DN Artwork: Measurement and Design The Sigma 50mm f/1.4 DG DN feels much less chunky than earlier generations of Artwork lenses, and it weighs simply 670 grams (23.6 ounces) on L-Mount and 660 grams (23.3 ounces) on Sony E-Mount. The Sony model is 78.2mm by 111.5mm (3.1 inches by 4.4 inches), which is only a fraction of an inch greater than the L-Mount model. The solid-feeling lens barrel has an aperture ring, an aperture click on/declick swap, and an aperture lock swap. There may be additionally a spotlight mode swap and, on the L-mount system, the main focus ring will be switched between a linear and non-linear focus adjustment. Mounted to the Sony a7R V, the lens is a tad front-heavy however not almost as a lot because the Sony Zeiss lens, which is round 120 grams (4.23 ounces) heavier than the Sigma. The Sigma can be narrower than the Sony Zeiss lens and barely taller.
The Sigma 50mm f/1.4 is usually snug to make use of, though the width of the barrel brings it shut sufficient to the grip that these with giant fingers may discover it uncomfortable. It is a fairly typical trade-off for the smaller measurement of mirrorless cameras, but it surely’s one thing to bear in mind. Sigma 50mm f/1.4 DG DN Artwork: Operation My first ideas when utilizing high-end third-party lenses often are, “that’s good,” however my first ideas with the Sigma 50mm f/1.4 had been as a substitute, “that’s nice.” Focus pace is spectacular, as is focus accuracy. Whereas photographing at a neighborhood lake, the Sigma 50mm f/1.4 on the Sony a7R V might detect and observe tiny hen eyes no less than 20 meters away. Just a few folks purchase a 50mm lens for wildlife pictures. Nonetheless, the truth that the lens can lock onto such a tiny reference level at a distance and preserve it exhibits how the brand new focusing system within the Sigma 50mm f/1.4 DG DN works in tandem with Sony’s subject-detection AF system. Eye detection on birds with the Sony a7R V and the Sigma 50mm f/1.4 DG DN is simply pretty much as good as with native glass. For human topics at a regular portrait distance, the Sigma 50mm f/1.4 DG DN locks onto eyes with the identical agility and tenacity as any lens I’ve used. Like with Sony’s first-party lenses, the brand new Sigma lens performs quick sufficient to nail photographs repeatedly. Sometimes, third-party lenses can lock onto no matter topic the connected digicam is designed to detect however lose focus if the themes transfer rapidly.
An necessary factor to recollect with a super-wide aperture lens is how slim your discipline of view is. With the quick focus of the Sigma lens, I discovered myself capturing large open fairly a bit, the place typically even minor actions of myself or my topic whereas capturing a burst of photographs might transfer the main focus level. The TLDR right here is that an f/1.4 lens wants extra care when choosing shutter speeds than different apertures. Sigma 50mm f/1.4 DG DN Artwork: Velocity vs. Sony Glass When capturing with the Sigma 50mm f/1.4 on the Sony a1, the utmost body fee of the lens caps out at 15fps versus the 30fps of native glass. That is due, Sony has advised me previously, to the truth that its engineers know easy methods to maximize the communication between the lenses and the digicam’s focusing system to maximise the efficiency of a lens’ operation. This makes logical sense, although an alternate chance is that Sony limits the pace of third-party glass to 15fps to cut back competitors. This lens will function at full pace of most Sony digicam AF methods however at half pace on the Sony A1 and a9/a9 II. Future Sony cameras with high-speed seize charges will probably have the identical limitation. This seize fee limitation is not going to influence the standard portrait shooter, however it’s one thing to bear in mind if the lens is used for sports activities or high-action pictures. Sigma 50mm f/1.4 DG DN Artwork: Picture High quality Photographs captured with the Sigma 50mm f/1.4 DG DN are very good. Even large open, the lens can seize and render human eyes with improbable high quality, and the 11-bladed aperture creates delicate, light background defocus.
Stopped down the lens produces glorious environmental portraits, with sufficient rendition of background to set a scene however with a softness that masks particulars sufficient to forestall them from overpowering a scene. Sigma’s Artwork lenses are recognized for his or her high-resolution rendition of a scene, and the 50mm Artwork is not any exception. Strains and particulars on faces are rendered completely, and the pictures have glorious distinction. In some checks, the lens leans a bit towards reds, however Sigma warned us that it is a preproduction lens and preproduction firmware, and it’s not an awesome shift. As talked about, I mixed the Sigma 50mm f/1.4 DG DN with the high-resolution Sony a7R V, and the outcomes are spectacular. Due to the excessive pixel depend, it’s attainable to crop into a picture for very good particulars. On just a few events, I seen that the JPEG model of a RAW+JPEG shot had the vertical airplane elongated, however I couldn’t discover a solution to trigger this to occur deliberately. The RAW recordsdata didn’t present cases of this elongation, so probably this was attributable to some communication challenge between the beta firmware and the cameras’ JEPG rendering. Once more, that is preproduction firmware, so this sort of challenge is anticipated.

Nonetheless, Sigma has all the time struck a pleasant stability between worth and high quality. The Sigma 50mm f/1.4 DG DN Artwork is not any exception. With a worth of $850, the Sigma 50mm f/1.4 is round half the worth of the present Sony 50mm ZA and greater than $1000 cheaper than the Sony 50mm F1.2 GM. ©2023 Henry Schloss
It is a improbable worth contemplating the efficiency enhancements introduced with the HLA motors on this lens. Whereas I’ll want to judge this lens absolutely when manufacturing fashions can be found, even this preproduction mannequin of the Sigma f/1.4 DG DN properly exceeded my expectations. The 15 frames per second seize fee limitation could lead some to pick the Sony 50mm f/1.2 GM over the Sigma f/1.4. DG DN Artwork, however for many goal prospects, it is a limitation with out a lot implication. It will likely be arduous to discover a cause to not purchase the Sigma 50mm f/1.4 DG DN Artwork lens when it turns into accessible. This Sigma lens is prone to turn out to be one of many lenses in opposition to which different 50mm lenses are judged. Are There Options? There are such a lot of options within the 50mm focal size for the Sony E-Mount. Adorama has greater than 5 dozen lenses within the focal size for this platform, although this consists of many guide focus lenses, kit-quality lenses, and several other items of glass far more costly than this. The closest lenses on this class is the almost $2,000 Sony 50mm f/1.2 GM and the $1,500 Sony Zeiss 50mm f/1.4 lens. These are each dearer and, as talked about, aren’t as performant throughout the board. Ought to You Purchase It? Sure. Till we see a brand new Sony-made 50mm f/1.4 G or GM lens, there isn’t something within the class that’s as quick, correct, and reasonably priced because the Sigma 50mm f/1.4 DG DN Artwork.
