The lens has a 35mm equivalent focal length of 20mm on a standard Four Thirds camera.
Joining the other MFT mount SLR Magic Hyperprimes is the 10mm T2.1 Hyperprime Cine lens. Designed specifically for use with MFT mount cameras with Four Thirds sized sensors the lens strikes a useful balance between size, form, and function. The 10mm lens features sharp images exhibiting little corner and edge distortion, even when the iris is at its maximum opening of T2.1.
The lens' Cine designation refers to the geared focus and iris rings, which feature 0.8 pitch teeth for compatibility with film style follow focus units. The clickless iris ring allows you to adjust the aperture during the shot for smooth iris pulls. The front of the lens does not rotate as you change focus and is threaded to accept threaded 77mm filters or filter rings.
