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

• For use with smaller chip APS-c cameras only

• The circular field of view produces striking images with exaggerated perspective of near subject & extreme barrel distortion of the surrounding areas

• HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus

• The minimum focusing distance of 5.3 inches & a magnification ratio of 1 to 6 allows subjects to be as close as ¾ of an inch from the lenses’ front element.

• A front cap adapter, front/rear lens cap and carrying case are included with the lens.

Sigma’s 4.5mm F2.8 EX DC Circular Fisheye HSM creates an image that is a circular, curved, distorted view of reality when used on a digital SLR camera. One of the most unusual lenses a photographer can use as it produces a circular image within a black surrounding frame. It is ideal for landscapes and panoramic photography. Because of its equisolid angle projection system, the lens can be used for scientific applications. The minimum focusing distance of 5.3 inches allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. SLD (Special Low Dispersion) glass employed for effective compensation of color aberration, Super Multi-Layer lens coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. In the hands of a photographer looking for creative expression and the opportunity to explore and create, this is the ultimate creative tool. The results are captivating.

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.

Close-up Photography

This circular fisheye lens has a minimum focusing distance of 13.5cm and a maximum magnification of 1:6 making it particularly useful for close-up photography.

Excellent optical performance

SLD (Special Low Dispersion) glass provides effective compensation of chromatic aberration and Sigma’s Super Multi-Layer coating minimises flare and ghosting.

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.

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.

Gelatin Filter Holder

A holder at the rear of the lens accepts gelatin filters.
