Sigma Imaging (UK) Ltd

	Ephotozine - August 2005 ‘Being designed for cropped sensors only, the lens is light in weight and, being compact as well, can easily be carried on the camera all day as a walkabout lens.’

	Outdoor Photography - December 2005 ‘Measuring a little under 8cm in length and weighing under half a kilo, this is a compact lens that can be carried comftably on the camera all day. Finished in matt black, it has a smart appearance and comes complete with a petal shaped lens hood.’ ‘…it focuses down to 45cm at all focal lengths with a maximum magnification of 1:4.4. This is useful for close-up work of subjects such as flowerheads or dragonflies as well as producing dynamic wide-angle images with bags of impact.’

	Which Digital Camera - July 2006 ‘The Sigma’s neat compact design is very appealing and it definitely looks the part. This lens is easy to operate, and includes a locking switch on the zoom barrel at 18mm setting, which prevents the zoom creeping out when it’s not in use.’

	Photography Monthly - July 2006 ‘Typically Sigma, this lens is attractively finished and handles well.’ ‘All in all, this is a nice lens that performs respectably. It sells at an attractive price and is compact enough.’

	Camera Labs - July 2006 ‘Delivering a focal range equivalent to 27-300mm, the Sigma 18-200mm f/3.5-6.3 DC is a highly versatile lens. Its massive 11.1x zoom range allows you to capture both wide landscape shots and decent close-ups of distant subjects such as wildlife without worrying about carrying additional lenses.’ ‘Indeed many photographers could fit one and never take it off again – and that’s not only highly convenient but also greatly reduces the potential for dust to enter the camera body.’

	Digital Camera Shopper - April 2007 ‘Sharpness, contrast and colour rendition were all very good, even when shooting wide open, but it became noticeably better when stopping down by even a single stop.’ ‘A good performer all round, the Sigma 18-200 is the ideal lens to put on your camera when you want to travel light.’

	Digital SLR User - September 2007 ‘At its current price the Sigma is only rivalled by the original Tamron 18-200mm, and so will a good choice for the average user who wants an all-purpose lens without crippling their finances… this is a quality lens for the price tag and is definitely worth a look.’
