Sigma has announced the new Sigma 18-35mm f/1.8 DC lens for APS-C (crop) sensor Digital SLRs.
It is an A- Art series lens that has a constant f/1.8 aperture. It is the first zoom lens ever to achieve a maximum aperture of f1.8 throughout the zoom range.
Take a look at our Sigma 18-35mm f/1.8 Hands-On Preview
The lens has a focal range equivalent to 27-52.5mm in a 35mm format and it can cover the angles of view of multiple fixed focal length lenses. This wide aperture, standard zoom lens enables the photographer to expand creative possibilities on any occasion.
Flare and ghosting were thoroughly measured and monitored from an early stage in the lenses development to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. Attaching the matched petal type hood, which is supplied, will provide extra protection from flare and ghosting.
With a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.3, this lens is excellent for close-up photography.
