Sigma’s 8mm f/3.5 EX DG Circular Fisheye are a unique approach to creative photography. Images created by fisheyes are a circular, curved distorted view of reality. It allows photographers to shoot creative images by taking advantage of the acute perspectives that are invisible to the human eye. This Sigma fisheye produces a circular image with a 180 degree angle of view within a black surrounding frame. A minimum focusing distance of 5.3 inch and a magnification ratio of 1 to 4.6 allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. For photographers looking for a creative venue this Sigma fisheye is a good choice.

DG for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. DG lenses provide exceptionally high contrast along with subtle gradations in tone and color. Super Multi-Layer Coating, along with Sigma's optimized optical design work to reduce reflections between the image sensor and the lens surfaces. The large image circles of DG lenses mean there will always be enough peripheral illumination to avoid vignetting.

EX Lens

The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.

Auto-Focus System

This circular fisheye lens produces circular images with an angle of view of 180°and also incorporates an auto focus system to achieve accurate focusing that might be difficult through the camera`s viewfinder due to the extremely large depth of field.

f/3.5 Maximum Aperture

This lens is perfectly suited for low light conditions indoors or at dusk.

Close-up Photography

This circular fisheye lens has a minimum focusing distance of 13.5cm (5.3 inch) and a maximum magnification of 1:4.6 making it particularly useful for close-up photography.

Excellent Optical Performance

Special Low Dispersion (SLD) glass offer effective compensation of color aberration.

Flare and Ghosting Reduction

Sigma's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.

An Ideal Lens for Scientific Applications

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.
