The PRO5820PHD diagonal fisheye wide angle conversion lens is designed exclusively for professional whom demand the highest and widest angle of coverage without compromising on image quality.

The PRO HD optical used in PRO5820PHD is constructed using a precise polished 3-group / 3-element optical system which are coated with broadband anti-reflection multi coating to allow maximum light transmission and at the same time prevents unwanted internal flare, reflection and ghosting from entering the lens. Individual optical glass is grounded and polished to exact dimension to attain high resolution for maximum clarity throughout the entire picture. When mounted onto DSLR lens, the maximum field of view is extended significantly by a factor of 0.2x, enabling super wide pictures to be taken with fisheye effect at the maximum wide angle position.

All factors to produce HD images are taken into consideration in the manufacture of this precise super wide fisheye lens. It includes darken glass edges with polished sides, professional matt housing, sure grip for better lens handling and a 105mm front filter thread for filter placement.
