p.1 #15 · Zeiss cine vs. ZF(ZK, ZE) lenses | |
The compact primes are the 'same' optics as the ZF lenses. Click on the FAQ section and Zeiss says so. I'm sure they are assembled more carefully, etc., but the optical design is the same. So they should cover 24x36. I think you are probably just paying extra for cine style housings (which I'd not want to use in a still setting) and probably higher quality control.
The Master and Ultra primes are different.
Cinematography does have different requirements. First of all, the real expensive primes have the same maximum aperture across the line to help give a consistent look. Also, they are probably sharper across the frame, less distortion, etc. But then again, at about $20k per lens for the Master primes, they should be. They are higher quality for two reasons probably - first giant enlargments (40x60 feet from a smaller negative than 24x36) - secondly, whats $20k when your movie cost $200 million to make?
The other requirement for cine lenses is consistent sizes. And larger isn't necessarily a bad thing. You hang a lot more stuff off a cine lens, like matte boxes, flags, and follow focus devices. You also often have multiple people working on the camera and lens; one guy pulling focus, one operating the camera, etc. So the extra size can be a good thing.
