Sigma 10mm F2.8 DC HSM Diagonal Fisheye lens

Suitable for DC format SLR cameras.
Not suitable for Full frame SLRs or film SLR cameras

This autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The Nikon version produces a diagonal angle of view of 180 degrees (154 degrees for Sigma, 167 degrees for Canon). The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion.

Close-up Photography-
The minimum focusing distance of 13.5cm, and maximum magnification 1:3.3 allows subjects to be as close as 1.8cm from the lens’ front element. The close focusing capability together with a large depth of field allow close up photography that covers objects surrounding the photographic subject.

Excellent optical performance-
The Integral hood blocks out extraneous light and the Super Multi-Layer Coating minimizes flare and ghosting, creating superior image quality.

High speed auto focus-
It is equipped with an inner focusing system that creates high definition and excellent image quality over the whole frame. The HSM(Hyper Sonic Motor)ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.

Fast F2.8 maximum aperture-
The fast f/2.8 maximum aperture produces a bright image in the viewfinder making this lens ideal for low light photography.

Ideal for panoramic and scientific applications-
This lens is ideal for photographers using computer stitching software which requires circular fisheye images to be input, resulting in stitched panoramas. Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific applications such as solid angle measurements of cloud distribution over the sky, or vegetation distribution of the rain forest canopy.
