High level optical performance

SLD (Super Low Dispersion) glass provides effective compensation of color aberration.

HSM (Hyper Sonic Motor)

The HSM ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.

EX | HSM | IF

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 focal 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 captivatin.


The first circular fisheye lens exclusively for use with APS-C size digital SLR cameras.

This autofocus circular fisheye lens is designed exclusively for digital SLR cameras with an APS-C size image sensor. It produces circular image with digital SLR cameras. The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly useful for close-up photography. SLD (Special Low Dispersion) glass, Super Multi-Layer Coating and the inner focusing system creates high image quality. The HSM (Hyper Sonic Motor) ensures fast and quiet autofocusing and allows full-time manual focus override.

The first circular fisheye lens exclusively for use with APS-C size digital SLR cameras

This lens is the first circular fisheye lens designed for APS-C size digital SLR cameras. It produces circular image with a diameter of 12.3mm and angle of view of 180 degree in all directions, making it ideal for capturing 360 degree panoramas.

Equisolid angle projection system

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.

High level optical performance

SLD (Super Low Dispersion) glass provides effective compensation of color aberration. Sigma's Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with inner focusing system that creates high definition and excellent image quality over the whole frame.

The close focusing capability allows close-up photography

The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly useful for close-up photography.

F2.8 Large aperture

It is an ideal lens for Astrophotography and Aurora photography. The large depth of field enables photographers to emphasize the subject.

Convenience for photographers

This lens is equipped with a gelatin filter holder at the rear, allowing the use of gelatin filters. The front cap adapter for attachment of the 72mm front cap is included.
