Arai up lens refers to a series of film photography lenses jointly launched by Arai and Carl Zeiss.

The full name of the up lens is ultra prime. Like the CP and MP series lenses, they are a series of lenses jointly launched by the famous German film camera manufacturer Alai and the equally famous German Carl Zeiss, and eventually formed industry standard. Many third-party lens manufacturers also produce lenses according to this standard, such as the famous German Leica, Schneider, Rodensted, etc., the American Keka, the French Angenieux (Ai Channeng), Japan's Canon, Tokina, and South Korea's Sanyang et al.

The former of the CP and MP series lenses are low-end entry-level lenses (not low-end), and are mainly used for small crews or ordinary TV drama shootings. If micro-film lovers can get or use them, they can really brag. hehe. MP series lenses are mainly high-end and are often used by large film crews or used in elaborate advertisements. They often have larger diameters and unparalleled optical quality. Our up lenses are mainly mid-range and are the lens series most used by major domestic film crews.
