Medium format refers to a category of film and digital cameras that use a larger image sensor or film size than standard 35mm cameras. Typically, medium format cameras capture images in sizes ranging from 6x4.5 cm to 6x9 cm for film, or sensors that are approximately 44x33 mm or larger for digital. This larger size allows for greater detail and improved image quality, making medium format popular among professional photographers. Due to their size, medium format cameras often come with a higher price tag and are generally bulkier than smaller formats. They are favored for specific types of photography, such as landscape photography, portrait photography, and commercial photography, where image quality is paramount.
