Sigma Imaging (UK) Ltd

	Digital Photo - April 2006 ' …it offers a substantial zoom grip and focus ring, complete with distance measurements, a depth-of-field guide and a magnification ratio guide on the barrel. A switch on the side allows a macro setting of up to 1:2 at 300mm.' Digital Photo Silver Award

	Ephotozine - August 2005 ‘Prior to the DG upgrade, this lens already had an enormous reputation for its picture quality compared to its price. The upgrade has only enhanced this. The usefulness of the lens is greatly added to with its ability to focus down to less than a metre and anyone wishing to photograph large insects such as butterflies or dragonflies will find it one of the most useful lenses for this discipline, being light enough to carry on a neck strap all day with the focal length allowing the luxury of not needing to get too close.’

	Practical Photography - May 2006 'Our test chart shot reveals consistently sharp results all around the edges of the frame, highlighting this as a solid performer. The 1:2 macro mode works well too – proving this lens is a worthwhile and versatile addition to your kit bag.' '…with a better build quality and great results it proves itself to be a formidable lens and therefore earns our Best Buy award.'

	Digital SLR Photography - December 2006 ‘The zoom and manual focus rings are a decent size and have a very smooth action. Build quality is very good. Autofocus is responsive in all lighting conditions. The Sigma incorporates two SLD (Special Low Dispersion) elements in its optical construction and the result of this is that resolution is higher than average.’

	Digital Camera Shopper - April 2007 ‘The auto focus mechanism itself is impressively quick in normal operation, taking a mere 1.6 seconds from infinity to closest focus and back to infinity, in our tests. Impressive sharpness throughout the zoom range and speedy autofocus make this a very attractive lens at the price.’

	Photography Monthly - August 2007 ‘A decent sized zoom ring is provided, plus there’s also a ‘macro’ function. This does not offer true macro, but does allow an extra close focus option between 200-300mm and will give a reproduction ratio of 1:2 at its maximum.’ ‘The lens makes a good choice for insect chasers being light and focusing down to less than a metre.’

	What Digital Camera - September 2007 ‘The optic has a nice feel, thanks to the matt-velvet paint that Sigma uses to coat its lens barrels with. The lens chart shows good performance at the 70mm end, with excellent control over fringing, particularly in corners where this lens is the clear leader. At 300mm, the central control is as good as that of the Nikon and Olympus models.’ What Digital Camera - Group Test Winner

	Which Digital Camera - December 2007 ‘Handling is sound, thanks to the well-sized zoom and focusing rings, plus there’s the added benefit of a 1:2 macro capability, accessed via a switch on the barrel of the lens between the 200mm and 300mm settings. Couple this with the 95cm close focus distance and you should be able to get some frame-filling macro images.’ ‘A consistent performer that has the added benefit of an impressive close-focusing capability.’

	Digital SLR User - December 2007 ‘The lens offers a Macro mode, which can be activated by a switch when used in the 200 – 300mm zoom range. This allows the lens to extend to its fullest extent for 1:2 macro shooting’ ‘One of the cheaper telephoto zooms on the market, the sigma is something of a bargain’

	Digital Photographer - Issue 71 ‘If you’re looking for a low-cost telephoto zoom to supplement your kit lens, you can hardly do better than this. The Sigma delivers handling and image quality beyond what you’d expect at this price.’

	Digital Camera Buyer - Issue 73 ‘The low cost isn’t reflected in the build quality either. Sigma’s familiar matte black finish means that this lens feels as tough and smart as Sigma’s more expensive optics.’ ‘The Sigma’s handling, build and performance are higher than would be expected in a lens at this price, and as a result, it’s hard to find anything to say against it.’
