The 16mm F1.4 lens gives you an equivalent of 24mm with a DX camera, such as the Nikon Z30, Nikon Z50 or Nikon Zfc. This is a good “standard” walkaround length for typical subjects such as landscape and even street photography work. It’s significantly wider than the closest Nikon DX lens prime lens, which is the Nikkor Z DX 24mm f/1.7 lens, which gives an equivalent focal length of 36mm. Chromatic aberrations, typically seen as purple or blue fringes along contrasty edges, can be detected in quite a lot of our sample shots - this is definitely one of the Sigma 16mm F1.4 DC DN C's weaker points in terms of image quality. These lenses provide an angle-of-view equivalent to a 24mm, 45mm and 84mm lens in a 35mm system. Each one offers a very bright f/1.4 maximum aperture and an iris diaphragm with nine rounded blades for excellent low-light and shallow depth-of-field shooting.

With 16 elements in 13 groups, the optical system features a multitude of high-tech and high-end components, including three FLD glass elements, two SLD glass elements, and two moulded glass aspherical elements. This optical system minimizes optical aberrations and ensures outstanding resolution at wide-open aperture and throughout the aperture range. In particular, the two aspherical lens elements have ultra-high-precision surfaces polished to tolerances under 10 nanometers, minimizing the onion ring bokeh effect that some aspherical elements produce and ensuring clear image quality throughout the frame. In addition, the structure of the optical system gently bends light to minimize sagittal coma flare and deliver optimal optical performance from the center of the frame to the edges. The result is a smooth, round bokeh effect with ample light volume throughout the frame. The first in this SIGMA series of prime lenses for mirrorless cameras was the standard prime 30mm F1.4 DC DN | Contemporary, now followed by the wide-angle prime 16mm F1.4 DC DN | Contemporary. Going forward, SIGMA will add a telephoto lens to the series, making it a new and complete system for mirrorless camera users. We didn't experience very much "hunting", either in good or bad light, with the lens accurately focusing almost all of the time. It's also a very quiet performer, thanks to the built-in stepping AF motor, which makes this lens well-suited to video recording. Like the 30mm, it has a close minimum focusing distance. With that wide f/1.4 aperture, it is possible to get an excellent shallow depth of field. The lens looks very nice and has a sleek, smooth design and finish. It pairs quite well with a Sony camera and doesn't look dissimilar from some of Sony's own lenses. The large focus ring has a rubberized finish and feels very nice to use, plus it's wide at just under a couple inches (around 50 millimeters). The lens looks good and balances well with the A6500.

Internal conversations with Sigma insiders reveals that the popularity of Sony’s E mount (and its evolution to the more premium a6xxx series) caught Sigma a little by surprise, and this second wave of lenses (and their more premium nature) makes for a better match with Sony’s own evolution. Having owned and used the 30mm f/1.4 DN lens, I was excited for the release of the new Sigma 16mm f/1.4 DC DN Contemporary as a reasonably priced, premium wide angle option. If you own Micro 4/3rds or Sony APS-C E-mount, the 16mm DN should be a serious interest to you. The lens can focus to just under 10 inches (25 centimeters), which provides a maximum magnification ratio of 1:9.9. This is clearly not a lens well-suited for macro photography. However, this close focus distance is sufficient if you want to utilize close foreground elements in landscape images or capture close-up portraits. With the Sigma 16mm, 30mm and 56mm F1.4 DC DN C lens wide open at f/1.4, you can see some obvious light fall-off in the corners. Stopping down helps, although to completely get rid of this phenomenon, you will need to use an f-stop of f/4 or smaller. Light Fall-off - Sigma 16mm F1.4 DC DN C

Weighing in at a modest 380g, without hood or caps, the lens is by no means a burden. It is supplied with a solid petal lens hood that bayonets cleanly into place. This surrounds a filter thread of 67mm.The only other adornment is the wide, electronically operating, manual focusing ring. This is very smooth and probably best switched off in camera if MF is not being used. Otherwise, the natural grip on the lens barrel also grips the ring, which could be accidentally moved. As the MF function works with the AF system this could be an issue for some. However, as the AF is so fast and silent, thanks to the excellent stepping motor used, there is little motivation for manual focus in general use. One exception could be macro photography, where small manual adjustments to the point of focus can be useful. As this use would probably involve mounting the camera on a tripod, there would be no issue with accidental shifting of the focus point. Optical construction is 16 elements in 13 groups, and interestingly the instruction leaflet makes a point of informing that all the glass used is both Lead and Arsenic free. This is relevant to environmental issues if and when the lens is finally disposed of. There are various special lens elements, including 2 moulded glass aspheric, 2 SLD (Super Low Dispersion) and 3 FLD (Fluorite-like Low Dispersion). The FLD glass performs in a way very similar to a fluorite element, helping to reduce chromatic aberration even further. Fluorite elements are both expensive and quite brittle, so the FLD glass can be used with a very similar end result. There are 9 rounded diaphragm blades, aimed at making the aperture as circular as possible for improved bokeh. The optical design and stepping motor deliver smooth autofocus during video shooting. The lens design fully accommodates the Fast Hybrid AF of Sony E-mount cameras for super-fast autofocus functionality. Using face recognition AF results in consistent autofocusing on faces, even as the subjects move. The new SIGMA 16mm F1.4 DC DN | Contemporary is the world's first interchangeable lens for mirrorless Sony E-mount cameras in the APS-C format to offer a 24mm focal length (35mm equivalent) and F1.4 brightness. The lens for Micro Four Thirds offers a 32mm focal length (35mm equivalent) with the same f-number of 1.4. This is the large-diameter wide-angle lens for which mirrorless camera users have been waiting. It's a bit of a different lens when paired with a Micro Four Thirds camera. The sensor is smaller than APS-C, so its angle of view is more like a 32mm—a more moderate swath of coverage. Here the lens has some peers, including the svelte Olympus 17mm f/1.8 and Panasonic 15mm f/1.7, both of which are a little more expensive and gather a bit less light when shot wide open, but are very light and compact. And there's the premium Olympus 17mm f/1.2, which captures more light than the Sigma and features a manual focus clutch, but is a lot more expensive.But what the Canon 11-22mm’s Image Stabilization? Does it produce better footage than the Sigma 16mm which does not have IS? For about a year now, I’ve been filming all my travel vlog content using a Canon M50 with a Canon 11-22mm EF-M variable zoom lens. As much as I like the 11-22mm, I’ve unfortunately been bitten more than once by its small f/4-5.6 aperture. Not a problem when shooting video outdoors in plenty of light, but in low light, I’ve had to raise the M50’s ISO super high to compensate which causes footage to lose sharpness and display noise. If the lens is Sony E fit, then the APS-C format gives an equivalent of 24mm, a classic ultra-wide focal length. This would also be an excellent lens for street photography, landscapes and architecture, although it is always possible to use lenses outside their normal, accepted applications, sometimes to very good effect. Naturally, there’s not a whole of point in having a fast f/1.4 lens if image quality doesn’t hold up when shooting wide-open. As it turns out, sharpness and contrast are maintained very well at the widest aperture. Another bonus is that the wide aperture and short 25cm minimum focus distance enable a fairly tight depth of field and good bokeh, enabling interesting perspective effects. I should note here that the lens is easy to add filters to at a very common 67mm size, which certainly adds to the value as a landscape lens. I like to add ND filters for allowing for longer shutter speeds, and in some situations a circular polarizer can reduce reflections, add contrast, and deepen color saturation. The focal length is not so wide that you should get too many weird “polarizing” effects in blue skies. All of the focus takes place internally, and nothing rotates at the front, which makes using a polarizer more simple. Flare Resistance, Chromatic Aberrations, Bokeh, and Distortion
