30x29mm

30x29mm is a standard size for film used in medium format photography. It is also known as 35mm medium format, referring to the width of the film, which is 35 millimeters. The length of the film is 29 millimeters, which is slightly shorter than the 36mm used in 35mm film for 35mm cameras. This size offers a larger image area compared to 35mm film, providing greater detail and dynamic range. It is commonly used in rangefinders, twin-lens reflex cameras, and medium format digital backs. The 30x29mm format is popular among photographers who seek a balance between the convenience of 35mm film and the image quality of large format photography.
