My APS-C format general purpose lens minimum focal length range recommendation is 18-45mm, which relates to 28.8-72mm in full frame format. The "DC" ("Digital Camera") in the name means that this lens is compatible only with ASP-C/1.6x FOVCF sensor format DSLR cameras. You need the focal length that is going to allow proper framing and proper perspective for your subjects. Let's start the review with a look at the focal length range as that is one of my primary criteria for lens selection. The downsides? A relatively short focal length range and lack of image stabilization are the only ones on my list. Just because a lens has a specific max aperture does not mean that you will want to use that aperture, but this lens rocks at f/1.8.Ĭombine excellent wide open image quality with a great looking, great performing and modest fixed-sized package along with a good price and you have a lens that is going to find a home in MANY kits. The f/1.8 max aperture, available over the entire focal length range, puts this zoom lens on a shelf by itself. In fact, f/1.8 is 1 1/3 stops wider/faster than the next-widest/fastest f/2.8 zoom lens crowd – allowing more than twice as much light to reach the camera sensor than the tied-for-second place lenses. The primary reason for that awesomeness is the not-seen-in-any-other-zoom-lens f/1.8 aperture. The word "groundbreaking" seems inadequate for describing the awesomeness of the Sigma 18-35mm f/1.8 DC HSM Art Lens. Expired: Also Hot: Save 20% on New EF and TS-E Lenses at Canon USA.

SIGMA 18 35 ART MANUAL
This AF motor can also be manually overridden at any time by rotating the focusing ring, giving you the ability to fine-tune image sharpness through manual focusing. The Hyper Sonic Motor provides fast, quiet, and smooth auto focusing that is well-suited for use with video applications. A Super Multi-Layer Coating also benefits the image quality by reducing reflections and flare and contributing to greater overall contrast and fidelity. The range of focal lengths it covers, from wide-angle to normal-length, is nicely situated for everyday and artistic shooting applications.įour aspherical lens elements, as well as the incorporation of five SLD glass elements, help to minimise the appearance of distortions and aberrations throughout the zoom range and provide clear imagery with enhanced sharpness. This lens is part of Sigma’s Art line deeming it well-suited to creative image making due to its large, constant f/1.8 maximum aperture and ability to produce aesthetic bokeh by way of a nine-blade circular diaphragm.
SIGMA 18 35 ART MOVIE
For control of focus, a Hyper Sonic Motor (HSM) is used to ensure fast, precise, and quiet focusing capabilities that are well suited to continuous shooting and movie recording. An internal focusing and zooming mechanism also helps to maintain a compact and consistent overall length and non-rotating front ring also better enables the use of circular polarising filters. The lens barrel design is constructed from a Thermally Stable Composite (TSC) material that is akin to metal in texture and resistance to temperature and environmental changes while also remaining lightweight and compact. A Super Multi-Layer Coating has also been applied to lens elements to reduce surface reflections, lens flare, and ghosting to produce images with higher contrast and colour fidelity. The lens integrates four aspherical elements into its construction as well as five Special Low Dispersion (SLD) glass elements to help minimize various aberrations and distortions throughout the zoom range as well as provide greater image sharpness and clarity. It is specifically designed for use with APS-C-sized sensors and provides a 35mm-equivalent focal length range of 28.8-56mm. The Sigma 18-35mm f/1.8 DC HSM Art Lens (for Canon) is a wide-angle to normal-length zoom lens that features a fast, bright constant f/1.8 maximum aperture.
