Large aperture F3.5 circular fisheye lens with close up capability, optimized for use with digital SLR cameras.

 

This circular fisheye lens produces circular images with an angle of view of 180°when attached to a full-frame digital SLR or 35mm film SLR camera. It has a fast maximum aperture of F3.5 and a minimum focusing distance of 13.5cm (5.3"). Sigma's super multi-layer coating and Special Low Dispersion (SLD) glass provide excellent image quality for digital and film SLR cameras. The special fisheye design allows maximum creative expression.

*Full circle can only be captured with full frame 35mm format digital SLR and film SLR cameras.

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.

F3.5 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") 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.

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.
