Sigma 4.5mm f/2.8 EX DC HSM Circular Fisheye Lens: £733.27

Canon Fit High Quality Circular Fisheye Lens

This auto focus circular fisheye lens has an angle of view of 180 degrees in all directions. It is exclusively designed for digital SLR cameras with the APS-C size image sensor. When used in conjunction with digital SLRs with APS-C size image sensors, it produces circular fisheye image within the frame. The fast f/2.8 maximum aperture produces a bright image in the viewfinder making this lens ideal for low light photography. 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.

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.
