I've heard that the Zeiss cine lenses (Compact Primes, Ultra Primes, etc...) are just rehoused ZE/ZF.2 lenses. Are there any differences in the glass between their lenses of same focal length (i.e. Zeiss Planar T* 50mm f/1.4 vs CP.2 50mm T2.1 vs UP 50mm T1.9)?
Other then a few tweaks, cine lenses generally have more aperture diaphragms to obtain smooth round bokeh.
Here are cine version's capabilities: (35mm cine lens)
- Fixed Focal Length
- 35mm Full-frame coverage (24 x 36mm)
- 14 High-precision Iris Blades
- Anti-reflex Coating
- Internal Light Traps
- Manual Focus / Manual Iris Focus Rotation
- 300° Calibrated Lens Scales
- Rugged Cine Style Housing
Here are photo lens traits:(35mm photo lens)
- 9 blades
- Exceptional Color Control
- T* Coating
As for the glass they are mostly the same except some cotings and light traps
