Sigma 402965 16 mm F1.4 DC DN Contemporary Sony E Lens - Black

Product Information

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 Architectural photography, large product photography, interior photography, and birthday parties are just a few uses for 16mm. The LH716-01 offers optimal protection to the front lens element, including protection from dust, water, fingers, limbs, etc., and from flare-inducing bright light. I’m also happy to say that the autofocus was very accurate. I rarely experienced missed shots, and this is important, especially when you consider the 16mm is an f1.4 lens, so sometimes, the depth of field can be pretty shallow, especially when you’re shooting closer. 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.

Sigma 16 mm f/1.4 (C) AF DC DN Lens for Canon EF-M X Mount

Exceptional sharpness, a bulletproof build and great autofocus all come together to create a mighty lens that won’t really break the bank. Samples taken from the outer extreme of the image circle, full-frame corners, can be counted on to show a lens's weakest performance. Most modern lenses have correction profiles available (including in-camera), and distortion can easily be removed using these. I bought into the MfT format knowing I was making some practical compromises for the conveniences of size and weight. I don't expect to pay through the nose for those.Mount an extension tube behind this lens to significantly decrease and increase those respective numbers. In this shot, we can see that there is some rather heavy lens flare from the lamp. This would not be easy to handle during post-processing, so this is something to keep in mind. See the below crop for a better look. Over the years, many of their lenses have been made out of this material, and generally, it’s shown to be long-lasting, scratch resistant, and strong. Still, distortion correction is destructive at the pixel level as some portion of the image must be stretched or the overall dimensions reduced.

Sigma 16mm f/1.4 DC DN | C review | Digital Camera World

Astigmatism is seen as points of light spreading into a line, either sagittal (radiating from the center of the image) or meridional (tangential, perpendicular to sagittal). Stopping down to f/2 produces a strong improvement in contrast, and details are very sharp at this setting. As of review time, Canon and Sony do not publish extension tube specs or manufacture these items in compatible mounts, but third-party extension tubes are available.Vignetting is correctable during post-processing with increased noise in the brightened areas being the penalty, or it can be embraced, using the effect to draw the viewer's eye to the center of the frame. In addition to reducing camera shake, the stabilized imaging sensor provides a still viewfinder image, enabling careful composition. The lens hood cuts harmful rays that can negatively affect photographs while also minimizing reflectivity within the hood itself. The hood also features a rubber construction and a non-slip groove to make it easy to hold in a variety of shooting situations. While telephoto lenses are more frequently used for sports, a 16mm angle of view allows a very different perspective at these events. Chromatic aberration (CA) is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.
