Sigma Imaging (UK) Ltd

	PhotoPlus 'Handling the sublime, with wonderfully smooth manual focusing to complement the Sigma’s dead-on autofocus accuracy. Best of all, the optical quality is absolutely top drawer, combining razor sharpness with glorious colour performance and bags of contrast.'

	Amateur Photographer 'With regards to controlling distortion, the Sigma 150mm is clearly a first-class optic.' 'Sigma has produced a good all-round performer that will be welcomed over a broad band of applications... it represents very good value.'

	Ephotozine 'A well made and thought out macro lens with enough focal length to enable skittish insect photography without putting them to flight. Quiet and faster focusing with the ability to restrict the focusing to the area you are working in improves the experience also. Good balance on the excellent tripod collar makes for easy tripod work.’

	F2 Freelance and Digital 'The Sigma 150mm f/2.8 Macro was, quite simply, excellent on full frame digital, excellent on full frame film, and stunning on APS-C sensor digital where the crop factor made it feel like having a 225mm f/2.8 for full frame which would focus larger than 1:1! This lens, tested in Nikon mount on the D2X, Fuji S3, Kodak DCS Pro SLR/n and Velvia 100 film would have to get our highest blob rating if we didn’t despise blob ratings. Of course it has won photo press awards already, and no wonder.'

	Professional Image Maker 'Photographers who specialize in natural history photography either for money or enjoyment are going to love this one!' ’The engineering of this lens is up to the usual high standard we expect from the maker.’ 'The performance of the Sigma was essentially flawless and in the field it was way ahead of all the other problems such as camera shake and subject movement – this is a lens you can trust to do any job.' ‘The 150mm lens however is a real beauty, right up there with the standard we have come to expect from Sigma.’

	Which Digital Camera 'Sigma’s EX Matt finish is smart and hardwearing. The broad manual focus ring has a quality feel and good ribbing, so is easy to grip. Focusing is internal so the lens doesn’t change size as you focus closer. AF is smooth and almost silent, thanks to Sigma’s Hypersonic Motor, and a three position focus limiter stops the lens hunting through its full range.’

	Photography Monthly 'This lens is professionally built with all the attributes that you could possibly want included. It’s quick and quiet in use and provides punchy image quality, plus it sports a price tag that won’t make your bank manager blanch.’

	Professional Photographer 'As a macro, it works well, with plenty of working distance to chase bugs and the like, but short enough to handhold. Professionally built and offering everything you could possibly want, this lens is quick, quiet and produces punchy images. And the price won’t make too big a dent in your bank balance either.’

	Digital Camera ’Closest focus distance is 0.38 metres but with a focal length of 150mm, you don’t need to get so close to start with.’ ‘With its 150mm focal length, HSM autofocus and sturdy tripod collar, the Sigma certainly has plenty going for it at the price point.’

	Digital SLR Photography ‘Image quality is superb, with bitingly sharp results throughout the aperture range’ ‘This is the perfect focal length for timid subjects like insects, allowing a practical working distance that minimises the risk of frightening them away. Despite its focal length and fast maximum aperture, the lens has quite a compact design. Its nicely balanced, well constructed and the tripod collar make it easy to switch from a horizontal to vertical format. Image quality is excellent, capturing very fine detail’

	Practical Photography ‘Giving 1:1 magnification at a focus distance of 38cm, this 150mm lens from Sigma is just right. The lens handles well, with a large manual focusing ring (a necessity for some macro shots where you can’t rely on autofocus. Having said that, autofocus is quiet and reasonably quick for a macro lens thanks to the HSM motor’.

	Paint ShopPro Photo ‘The images were the best from the Sigma lens. Although all of these lenses are 1:1, the Sigma seemed to get you just that little bit closer to the action. The colour reproduction was beautiful and edges were nice and clean. The build quality is also excellent – feeling very sturdy in the hand.’
