Here’s a cutaway of 3 ZEISS lenses shown at Cine Gear. At left and in middle–two SLR still lenses: Makro-Planar T* 2/100 and Planar T* 1.4/85. At right, Compact Prime 2.9/25. This is a great example of the extra engineering involved in making a Compact Prime motion picture lens, where the focus scale is expanded and critical focus is maintained on the move.
ZEISS Compact Primes changed the game: lenses with interchangeable mounts mean you don’t have to buy a different lens for each brand of camera. Compact Primes now come with PL, EF, MFT, F and E mounts in 18, 21, 25, 28, 35, 50, 50 Macro, 85, and 100 mm.
Carl Zeiss CP.2 lenses come with well-written and easy-to-follow instructions on how to change the mounts yourself. Unleash your inner lens technician.
