Sigma Imaging (UK) Ltd

	Ephotozine - October 2006 ‘For those needing this type of lens, for example when using software to create panoramics or for those involved in the scientific measurement of angles, where the output from this lens is quantifiable, this lens is an excellent tool. For those who just want to experiment with the unusual perspective of a 180° field of view, or even the somewhat reduced field if using the lens on a cropped sensor, then this lens is a high class example.’

	Professional Photographer - January 2007 ‘There is a filter holder fitted around the rear element to accept gelatin filters, which must be cut to size. Thoughtfully, Sigma supplies a metal template to assist in this procedure, something that Canon and Nikon would do well to note!’ ‘The optical performance is extraordinary considering the lens delivers circular images. Resolution at the centre of the frame is very high, even at the maximum aperture, and peaks between f/4 and f/11.’ ‘Image contrast and colour saturation are good, with chromatic aberrations also well controlled.’

	Practical Photography - May 2007 ‘This lens will give you the full circular image in your frame on both film SLRs and full-frame D-SLRs, so you’ll benefit from its full capability.’ ‘Lenses this short often suffer from flare in the lens elements but we found no such problems with this one, even shooting directly into bright light.’ ‘An incredibly niche lens but one that will give even mundane scenes a new twist.’

	Digital SLR User - October 2007 ‘In terms of image quality, the Sigma 8mm is highly capable, offering excellent resolution and coloured fringing on detail is kept so low that it is barely noticeable. Available in Canon, Nikon and, of course, Sigma Mounts, the Sigma 8mm is an excellent fisheye lens. It is well constructed and producing high quality images it makes a tempting choice compared to more expensive own brand options.’

	PhotoPlus - October 2007 ‘…if you want the ultimate in fish-eyed coverage then you have to check out Sigma’s 8mm. This provides 180 degree view of the world. On a camera like the EOS 400D, this circle is cropped, but you still get a unique fish-eye effect.

	Freelance Photographer - October/November 2007 ‘Offering apertures from f/3.5-22, the improved model is sharper and faster than the outgoing f/4, with an 11-element design and six-blade diaphragm providing the immediate technical differences. Offering a full circle reproduction on a full frame camera, or the slight cut-off seen here on the smaller Sigma SD14 sensor, the 8mm is one of those lenses that everyone should consider if looking to expand their horizons. This is a lens almost without competition and justifies the EX DG branding.’
