Thanks to its smooth, de-clicked aperture and ideal focal length, the 8mm T/3.8 Fisheye Cine Lens for Canon from Rokinon is a great lens for shooting video with your DSLR camera. It is designed to shoot with APS-C image sensors, for which it provides full frame coverage, creating an expanded perspective that covers the entire frame. For DSLR 's with a full frame sensor, this lens will produce pictures with a semi-circular image and close-ups will appear proportionately large for a dramatic effect. Its de-clicked aperture range runs from T/3.8 to T/22, providing a smooth, silent, jump-free transition when shooting video and its multi-layered, anti-reflective UMC coated lenses allow for clean light transmission and razor sharp images. Toothed focusing and aperture rings and bright, white numbering make controlling your image all the easier.
