12/5/2023 0 Comments Sigma 16mm 1.4 canon![]() ![]() The downside of this focal range is considerable deformation of human and animal subjects near the lens, especially towards the peripheral regions. For myself, I'd say that shooting in dark venues and astrophotography is where I'd personally find use for this lens. Still, there will be folks who want a wide fast lens for their own reasons. You wouldn't buy this lens just because it's wide because the 11-22mm would be considered more practical as a landscape lens with it's f/4 aperture. The obvious benefit of a bright 16mm lens is the ability to shoot in what would otherwise be considered to be "challenging light". ![]() However, this 16mm becomes 25mm (roughly) on APS-C and that isn't too far from 28mm - which was the standard for a wide-angle lens 20+ years ago. The one complaint that you will see online is that the 16mm FOV is too wide for general use (especially portrait use) on an APS-C camera. ![]() So was lens correction applied somehow in-camera? I'm guessing it was because a lens with these properties ought to have some degree of corner shading. Highlights from the images in this thread are a lack of light-falloff (soft vignetting) which I didn't see signs of, regardless of the OP stating they were SOOC. And this lens equates to 38.64mm on APS-C so distortion is low. But neither is the Sigma 16mm f/1.4 for that matter - now that local pricing has started to appear. Whist I consider the Canon EF 24mm f/1.4L lens to be the best lens out of nearly two dozen lenses that I've used on the EOS M cameras, not many people are going to shell out the extra money for one because they're not cheap. Other than this observation of the lens character, I found the OP's sample shots to be good. ![]() it's more like there's a nervousness to the structure of the bokeh balls that I didn't expect to see from this particular lens. It's not that the Sigma can't render an out of focus background. It made me run back over my EF 24mm f/1.4L II USM lens samples for similarly distant bokeh and there's certainly a loss of "quality" in the bokeh from the Sigma 16mm f/1.4 lens. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.The bokeh "balls" have too much texture. The bayonet mount is constructed from brass for ensured accuracy and durability.Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance.A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.Two aspherical elements are used to limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.Two Special Low Dispersion (SLD) elements and three F Low Dispersion (FLD) elements reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.Bright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over depth of field for achieving selective focus effects.Wide-angle prime is designed for APS-C-format Canon EF-M-mount mirrorless cameras and provides a 25.6mm equivalent focal length.As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes. ![]()
