Description

In this box sits the case with the lens and hood inside. The case is the padding - there is no foam. SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art, and Sports, where each line has a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. With the astonishing rendering performance that meets the high standard, along with landscapes, portraits still-life, close-up, and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture and starry skies and many other scenes. 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. Since the 50mm focal length has been a standard for decades, there are many alternatives to this lens in many price ranges. All major camera brands have 50mm f/1.4 lenses. And many of those brands also offer a less-expensive 50mm f/1.8 option.

Sigma is on something of a winning streak, with the 18-35mm f/1.8 lens winning the AP Zoom Lens of the Year award last year, and already this 50mm f/1.4 lens is a strong contender for our Fixed Lens category this year. The images it produces display a staggering amount of detail across the frame, and those shooting landscapes and travel images will be impressed with its edge-to-edge sharpness. The front element features Sigma’s water and oil repellent coating, which is designed to repel water drops and provide resistance to fingerprints This feature keeps this lens a viable option for those on the verge of switching to the mirrorless system. I see very little coma with this aspherical lens, and what little there is goes away as stopped down. 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.)One of the first things I noticed when using the lens is how quiet it is. The Hyper Sonic Motor (HSM) is fast and quiet, and it helps that just a quarter turn of the focus ring moves the lens from its 40cm minimum focus distance to infinity. With such a small turn required, you would think that accurate manual focusing would be difficult; however, the lens was easy to focus using the large viewfinder of the full-frame Canon EOS-1D Mark IV. I was able to focus very precisely, and while this was just as much to do with the chosen camera, the gearing of the lens and the slight firmness of the focusing ring make it possible. Once focused, the lens holds firm and doesn’t slip, requiring a quite definite turn to shift it from position. With a 40cm minimum focus distance, the Sigma 50mm f/1.4 lens provides a magnification of 1:5.6, which is respectable for a lens of this type, just don’t expect to take too many close-up images with it. If I had to shoot in the rain, I’d be more comfortable with a Canon EF 50mm f/1.2. It does have that weather-sealing feature. Alternatives The Sigma 50mm f/1.4 DG HSM is available in Canon EF-mount, Nikon F-mount (FX), Sony E-mount, and Sony A-mount. And it’s also available in the L-mount and Sigma mounts.

Canon EOS 6D + 50mm @ 50mm, ISO 125, 1/160, f/1.6 Canon EOS 6D + 50mm @ 50mm, ISO 100, 1/1000, f/1.4 Ghosting and Flare

As for sharpness and vignetting, this is where we can see some differences. At f/1.4, there was a noticeable amount of vignetting on this lens. The center was a fair bit brighter than the corners. Lateral chromatic aberration is even better controlled in the DN lens compared with its forebear, which was already very good. As such, there’s virtually no color fringing to be seen towards the edges and corners of the frame. Axial chromatic aberration is also minimal, so there’s very little fringing around high-contrast edges in scenes that fall just in front of or behind the plane of focus. Resistance to ghosting and flare is again impressive. Bokeh is lusciously soft and dreamy. We noticed some ‘onion ring’ effect with the DG lens in defocused lights and bright spots but this is much more minimal in the DN lens. As far as sharpness is concerned, this lens puts in an excellent performance, especially in the centre of the frame. At f/1.4, sharpness in the centre is already outstanding, although clarity towards the edges of the frame lags behind somewhat. Sharpness towards the edges of the frame improves as the aperture is stopped down, reaching very good levels by f/2.8 and outstanding levels by f/4.

Although I am still waiting for the Nikon version of the Sigma 50mm f/1.4 Art to carefully analyze the lens using the high-resolution Nikon D800E, judging from the images I got out of the Canon 6D, I can say that the lens is very sharp wide open at f/1.4 – much sharper than the Nikon 50mm f/1.4G for sure! Center performance is excellent and peaks at the f/4 mark, while the corners start out a little weaker, but get pretty solid when stopped down to f/5.6. You can see lens performance comparisons to Zeiss Otus 55mm f/1.4, the older Sigma 50mm f/1.4, Nikkor 50mm f/1.4G and Nikkor 58mm f/1.4G in the lens comparisons section of the review, while the Imatest figures for the lens are shown below. Canon EOS 6D + 50mm @ 50mm, ISO 100, 1/160, f/1.4 Canon EOS 6D + 50mm @ 50mm, ISO 100, 1/1600, f/2.0 Sigma 50mm f/1.4 Art MTF Performance It's super sharp at every setting clear out to the corners, although just a little less sharp in the corners at f/1.4 due to a little bit of coma. It's very sharp in the corners at f/1.4, just quite not as sharp as at the center. If I was working in nasty, dirty areas, I'd forget the cap, and use an uncoated 77mm Tiffen UV filter instead. Uncoated filters are much easier to clean, but more prone to ghosting.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. The Sigma 50mm F1.4 DG HSM Art joins the highly regarded Sigma Art series of lenses as a favourite amongst photographers. We have found it is particularly popular for wedding, portraiture and gig photographers due to the focal range and wide maximum aperture. The F1.4 aperture is not only perfect for lower light conditions that you might find at weddings or gigs, but you have the ability to really play with your depth of field to create unique and interesting images. The 50mm f/1.4 DG HSM Art is Sigma’s second version of this lens. It replaces the older 50mm f/1.4 DG EX lens. The Art series was designed to provide a faster and sharper solution than its predecessor with better build quality and handling.

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.I may be a little weird, but I always invest long term. I'd be shy about this Sigma lens because I demand the lens I buy today to be earning money for me for at least the next 20 years, and to still be serviceable and valuable when I sell the lens after all that time. My Nikon and Canon pro lenses do this for me. I bought my Nikon 17-35mm f/2.8 AF-S in the 1990s, and it's still Nikon's top professional ultrawide zoom 15 years later (the Nikon 16-35 VR is only a consumer lens, and the Nikon 14-24 is a special-purpose lens much less useful than the 17-35). My 17-35/2.8 is still worth, used, what I paid for it new. As the version of the lens that I tested was the Canon mount, it seems best to mention the three options that Canon offers as alternatives:
