What do cp lens and up lens mean respectively? What's the difference?

The cp lens refers to COMPACT Prime; the up lens refers to ULTRA Prime.

The same thing is that they are both ZEISS movie prime lenses, but the difference is that they are three different movies. Fixed focus lens grade:

Among them, CP is entry-level, and its optical performance and operability are basically the entry-level level of a cine lens. Generally low-cost micro-movies and low-cost promotional videos are more commonly used.

UP is ZEISS’s mainstream fixed focus, PL mount, large aperture, and good breathing control. It is basically the same as domestic TV series. As long as fixed focus is used, it is basically the UP group.

Of course, there are also high-end ones: MP is considered the top of the line from ZEISS, with its unique style of coating and top-notch breathing and distortion control. MP is mainly used in film and advertising shooting.
