Sigma Imaging (UK) Ltd

	Amateur Photographer - 25th March 2006 'The Suffix ‘DG’ indicates that steps have now been taken to optimise it for digital camera use. This is likely to concern the adjustment of anti-reflection coating to minimise the image degrading flare caused by reflections back into the lens from the polished surface of the photosensor.' 'Optically the Sigma 15mm f/2.8 tested here had a nose ahead of the Canon featured here.'

	Outdoor Photography - December 2006 ‘With an impressively close minimum focusing distance of 15cm, this lens allows you to fill the frame with certain subjects at its maximum reproduction ratio of 1:3.8. Coupled with the dramatic angle of view and the wide maximum aperture this allows you a great deal of control over creative close-ups.’ ‘As with all of Sigma’s EX series of lenses this one has a solid feel. The focusing ring is smooth and there is no unnecessary play.' ‘It is also a real ‘go anywhere’ lens. Its compact dimensions and tough build mean that you will be confident it will stand up to the rigours of shooting in the wilderness, while the inherent depth of field, wide maximum aperture and short focal length make it a good option if you know that you are going to have to shoot handheld.’

	Professional Photographer - January 2007 ‘Overall resolution is excellent. The level of colour saturation and contrast are excellent, whilst chromatic aberration is minimal.’ ‘Straight lines that run directly through the centre of the frame are rendered straight, whilst straight line near the edge display considerable barrel distortion, as is to be expected with a non-rectilinear design.’
