Sigma 12-24mm f/4.5-5.6 EX DG ASHPHERICAL HSM

This ultra wide angle zoom lens offers 122 degree super wide angle of view along the diagonal axis

Sigma will always be guaranteed a place in the history books as pioneers of the wide-angle zoom lens. Our advanced super wide angle technology was developed far earlier than any of our competitors.

Sigma designed and produced the first wide-angle zoom lens, the “zoom gamma 21-35mm F3.5-4.2”, in 1979. The wide-angle zoom category didn’t even exist before this date. The market comprised only standard and telephoto zoom lenses with most people believing that wide angle zooms were impossible to develop.

However Sigma’s advanced design and pioneering technology went on to prove them wrong and strongly influence subsequent product development.

Optimized for Digital SLR Cameras
Four Special Low Dispersion (SLD) glass elements are provided for effective compensation of colour aberration, which is a common problem with super-wide angle lenses. Two pieces of molded glass and three aspherical lenses, including two molded glass aspherical lens elements, offer excellent correction for linear distortion as well as all types of aberration.
It is an ideal lens for Digital SLR Cameras as well as film SLR cameras.

HSM (Hyper Sonic Motor)
Equipped with Hyper Sonic Motor (HSM) for Sigma, Nikon and Canon.
It is easy to revert to Manual Focus by simply turning the focusing ring and overriding the AF. An inner focus system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched, built-in petal shaped lens hood.

Minimum focusing distance of 28cm/11in. at all focal lengths
12-24mm F4.5-5.6 EX DG lens offers a minimum focusing distance of 28cm/11in. at all focal lengths.
The super-wide angle’s useful range of view offers the photographer greater freedom of expression.

Fixed Petal-type hood is incorporated
This lens is equipped with a fixed Petal-type hood to obtain a superior extraneous light-blocking effect.

	Amateur Photographer - February 2004 'The Sigma 12-24mm f/4.5-5.6 EX DG HSM is clearly a state-of-the-art, pioneering design. Given its focal-length range, performance is first class and certainly exceeded my expectations. ...a very high-quality lens that has been corrected to exceptional standards. For such wide-angles in a zoom, there are few obvious abberations.'

	Digital Photo - November 2005 ‘The zoom and focus rings feature large rubberised grips and provide plenty of resistance to avoid slipping. Auto-focus locks on well and the unit feels solid and dependable.

	Practical Photography - May 2006 'Designed to work on both film and digital cameras, this Sigma lens is the most versatile lens on the test and really looks like and impressive piece of pro gear too' 'If you want a hardwearing lens, then this may be your best choice'

	The Photographer - April 2005 'I have a Sigma 12-24mm full-frame EX DG HSM zoom on the 1Ds MkII and I have never seen anything like it in my life. Curvature at the edges is virtually non-existent and the effects I can get ... well it has totally re-inspired my photography.'

	Digital SLR Photography - January 2007 ’It’s beautifully made and the wide zoom and focusing rings are easy to grip and have a silky smooth action. The barrel features a focus window with hyperfocal scale and an integral petal hood to protect from flare. We tested the HSM version, which gave fast, smooth and silent AF that proved very responsive.’

	Ephotozine - January 2007 ’The one area where, with a lens of this type and extreme angle of view, that you would expect to see problems are in the area of distortion. However, the lens showed no signs of this problem and even when measured it proved to be well inside acceptable limits. These results are truly remarkable given the amount of correction needed.’

	Digital Photographer - Issue 53 ’As the widest corrected zoom generally available, with an angle of view at the wide end of 122 degrees on full-frame sensors or film, and distortion kept down to a minimum, it is an amazing piece of optical engineering. The results are truly remarkable given the amount of correction needed.’

	Photography Monthly - April 2007 ’The lens showed no noticeable signs of barrel distortion at either end of the focal range. This is truly remarkable given the amount of correction needed. A look at the charts shows that resolution is consistent from wide open to well past the f/11 mark. A corrected lens this wide, capable of being used on full frame, is unprecedented and is still very usable on cropped sensors.

	PhotoPlus - October 2007 ’Sigma’s 12-24mm zoom is a particularly awesome beast when used on the full frame digital SLRs that it was originally designed for. The 12mm setting is remarkable on a camera of this type – it is such a wide-angle of view that the front of the lens is a huge chunk of curved glass.’

	Which Digital Camera - October 2007 ’When it comes to performance, all the usual anomalies such as chromatic aberration and ghosting are well-controlled throughout both the zoom and aperture ranges. The lens showed no noticeable signs of barrel distortion at either end of the focal range – and that’s truly remarkable given the amount of correction needed. A corrected lens this wide, capable of being used full frame, is unprecedented.’
