Sigma Imaging (UK) Ltd

	Practical Photography - September 2006 ‘The results are excellent and the new close focusing makes the lens far more versatile than the competition. If it’s not quite long enough for your needs, investing in a teleconverter will quickly sort that out.’ ‘With a reduced close focus setting, the new 70-200mm is a worthy addition to your kit bag. With a fast maximum aperture, good autofocus and macro capability, what else could you ask for?’

	What Digital Camera - September 2006 ‘The previous version of this lens was a cracker, and now Sigma have revamped it and added a macro function too, making it a very attractive proposition.’ ‘The glass includes Apochromatic elements, Extra Low Dispersion and Special Low Dispersion elements. All these combine to correct distortion and colour and reduce chromatic aberrations.’ ‘The test charts show really good performance at 70mm, peaking at 5.6, which is not surprising, and staying high throughout.’ ‘It’s impressive, but not as expensive as similar lenses from the first-party manufacturers. But if you want speed, quality and versatility, the chunky Sigma 70-200mm lens is a belter.’

	Digital Photographer - Issue 50 ‘The increase in AF speed and the close focus ability warrant the upgrade and put this optic right up there in the top drawer. This is a great option at a good price and is a very versatile lens.’

	Amateur Photographer - 11th November 2006 ‘Overall, the build quality is excellent and the mount engineering is impressive. The complexity of internal group movement for focusing and zooming presents problems of which previous generations of engineers never dreamed.‘ ‘Curvilinear distortion presents no problems and vignetting, too, is kept well within working limits. In close-up, its macro range, for once a zoom can be recommended for copy work.’

	Digital Photo - December 2006 ‘This may seem pricey, but it’s actually amazing value – just check out the price for a comparable own-brand lens. The constant f/2.8 aperture makes it heavy, but it’s well balanced and comes with a tripod collar so you won’t put undue strain on the body mount. You also get a very bright viewfinder image. Optically it’s a fine performer with great close focusing ability…’

	Digital Photo Pro - June 2007 ‘This is another lens that oozes quality as soon as you pick it up… it has to be said that it simply feels like a pro lens should. A removable tripod bush is a useful accessory, maybe not for those looking to hand hold for press or sports work, but certainly for such things as close-ups, a subject that is perfectly capable of tackling thanks to the 100cm closest focus capability that is offered.’

	Photography Monthly - September 2007 ‘There is no noticeable distortion showing and measurements back this up. Chromatic aberrations throughout the range of both aperture and zoom measure negligible amounts that are well within acceptable parameters. Contrast is good and both ghosting and flare is well controlled.’ ‘…this lens is up there with the best of them, and at a considerable saving.’
