This focal length is optimal for nightscapes, and this lens's ultra-wide aperture is highly complementary for such use. Omitting the optical stabilization system reduces the size, weight, complexity, and cost, and the ultra-wide f/1.4 aperture feature aptly handles many low-light scenarios. As the aperture narrows, the entrance pupil size is reduced, and the mechanical vignetting absolves with the shapes becoming rounder. That means this Sigma seems a bit of a steal when compared to more recent releases form PanOly, which IMO are significantly overpriced.Removal is sometimes very challenging, and in some cases, flare effects can be quite destructive to image quality. With a minimum focus distance of 9.8" (250mm), this lens has a 0.10x maximum magnification spec, a very low number. It starts out with the 16mm f1.4’s sharpness, which is outstanding by the way. The photos come out just so crisp and with such nice depth. Center sharpness at f1.4 is excellent with the edges holding up quite well. As you stop it down, sharpness overall improves, especially the edges. The 16mm f1.4 DC DN Contemporary lens simply captures every little detail. However, if you are after the absolute maximum sharpness from this lens, I would say shoot around f5.6. to f8. Still, don’t be afraid to use this lens throughout its aperture range because it will give you superb results at pretty much any setting. The optics are just so good. Indeed, there are no built-in electronics at all, so focusing is a purely manual affair and you’ll also need to shoot in Manual mode, adjusting the aperture via the lens’s control ring, rather than from the host camera.

Again, you need to pay extra for the lens hood, which is sold as an ‘optional extra’ but is definitely worth having for reducing ghosting and flare, as well as giving physical protection to the front element. Unlike many ultra-wide zooms, this one has an attachment thread (55mm) for the easy fitment of filters. Image quality is very pleasing, on a par with that of the EF-M 15-45mm and 55-200mm lenses, although the image stabilizer is slightly less effective, rated at 3-stops. Mount an extension tube behind this lens to significantly decrease and increase those respective numbers. equivalent in FF/35mm terms? What's that got to do with this preview/review of a 32mm equivalent lens?Carrying on from the more mass-market standard and telephoto EF-M zoom lenses, this is the obvious choice for anybody wanting an ultra-wide viewing angle. Wide-angle zooms can be notoriously big and heavy, but this one has the same kind of retractable design as the EF-M 15-45mm lens, shoehorning seriously wide viewing into physical dimensions of just 61x58mm. The long-zoom aperture of f/5.6 is slightly wider than in the standard and telephoto zooms, and this lens also goes one better in terms of build quality, with a metal rather than plastic mounting plate. The focal length is always a primary consideration when selecting the ideal lens for a particular use.
