15mm F2.8 EX DG DIAGONAL FISHEYE

Digitally optimized diagonal fisheye auto-focus lens

This digitally optimized diagonal fisheye lens is equipped with a new multi-layer coating technology that reduces both flare and ghosting. By taking advantage of both the distortion aberration, specific to fisheye lenses and the minimum shooting distance of 15 cm (5.9 inches), the photographer can shoot creative images.

Flare and Ghosting

This digitally optimized diagonal fisheye lens is equipped with a new multi-layer coating technology that reduces both flare and ghosting. This also ensures an accurate color balance and high definition results.

Fisheye Lens Characteristic enables photographers to experience new image expression possibilities

180 degree field of view of this fisheye lens can be used to create amazing image expressions that cannot be seen with the human eye, such as exaggerated perspective and distortion.

Minimum Shooting Distance of 15cm (5.9in.)

The minimum shooting distance of this lens is only 15cm(5.9 inch) and it has maximum magnification of 1:3.8. Minimum shooting distance of 15cm (5.9in.) and large depth of field allow close up photography that covers the objects surrounding the photographic subject.

In the news

‘Fractionally larger and noticeably heavier than Canon’s 15mm full-frame diagonal fisheye lens, also on test, the Sigma boasts the same, fast f/2.8 maximum aperture and feels a bit better built. More importantly, the Sigma gave us sharper, crisper images throughout its aperture range and was particularly impressive at f/2.8. All in all, the Sigma 15mm is our top choice for a full-frame diagonal fisheye lens, and the fact that it’s £80 cheaper than the Canon is a bonus.

‘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.’

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.

‘Colour balance looked neutral on all the photos I took and was recorded accurately, with an excellent degree of tonal range throughout the pictures, especially in terms of shadow detail’ ‘At the beginning of this test, I must admit that I approached it with a degree of scepticism, wondering what it could add to my approach to wildlife and nature photography. At the end of the test, I knew the answer: it adds a great deal!! I was reluctant indeed to hand it back and have no hesitation in wholeheartedly recommending it’

‘The MTF data obtained indicate good sharpness, with resolution figures above the critical 0.25 cycles-per-pixel threshold between f/5.6 and f/16. This is a very solid performance that proves Sigma’s lens truly is a serious optic that should not be dismissed as a mere gimmick.’

‘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.

You will often find pros that specialise in weddings using them for shots of big groups as well as for creative images of the happy couple. Specialist panorama shooters use them too. Of course, £500 for this Sigma lens is still a great deal of money but it reminds competitively priced given the opposition. In the light of its rivals, there’s no doubt that the Sigma is great value and an impressive performer for the money and definitely worthy of inclusion in your bag.’

‘I love this lens! I always avoided fisheyes because I thought they were too extreme and gimmicky, but having taken the Sigma 15mm on a few trips, I’m hooked. The 180 degree angle-of-view and “bendy” distortion works brilliantly on the right subject.

It’s invaluable for creating unusual, striking images in everyday situations. It takes a lot for a lens to earn a permanent spot in my backpack, but this one already has and I’m looking forward to using it on future travels.’

This independent FX diagonal fisheye makes an affordable alternative. Image quality is good.’
