• DON'T FORGET TO PURCHASE YOUR UV FILTER FOR THIS LENS, IT'S HIGHLY RECOMMENDED!
This autofocus 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 image within the frame.
The F2.8 large aperture value produces a bright image in the viewfinder and allows photographers to take pictures in low light conditions, making it an ideal lens for Astrophotography and Aurora photography. Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific and arts applications such as solid angle measurements of cloud distribution over the sky or vegetation distribution of the forest.
The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly useful for close-up photography. SLDÂiSpecial Low DispersionÂjglass provides effective compensation of chromatic aberration. SigmaÂfs Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with an inner focusing system that creates high definition and good image quality over the whole frame. The HSMÂiHyper Sonic MotorÂjensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.
Now available for Sony/Minolta digital SLRs, and Pentax digital SLRs.
