A large number of medium format professional cameras are "system cameras", meaning they have a variety interchangeable components. Somewhat similar in
flexibility to a majority of
35 mm SLRs, these medium format cameras generally accept different lenses, and additionaly it is somewhat normal for medium-format camera systems to corroborate with different winding mechanisms,
viewfinders, camera backs and viewfinders. This adaptability is one of the foremost benefits of medium format in

Digital Medium Format
With the advancement of
digital camera backs,,
digital photography came kicking and screaming into the medium format world. Digital backs can be attached to many system cameras and fitted with electronic
sensors, successfully creating a digital camera from a
film camera. These digital backs are mostly used by professional
photographers. Similar to film, allowing for the expanded imaging chip size (as much as double that of a 35 mm film size), and as great as 40 times greater than a typical compact digital camera chip, they provide more
pixels with much lower noise. Attributes such as cooling fans also greatly improve the studio model image quality.
Medium Format Camera Types
Medium Format Camera Lenses A Medium format lens requires a longer focal length than a 35mm lens. A 50mm lens is thought of as a normal lens in 35mm film format, or a 35mm lens is normal for an APS- C Digital Camera, but these are wide-angle lenses on a medium format camera. But no matter what the lens focal length is, all lenses an identical focal length provide an the same exact depth-of-field. therefore a 100mm lens when mounted on a 35mm camera or medium format camera, yield the identical depth-of-field, although Medium format photographers must focus more precisely to obtain the necessary depth-of-fields.
Large and Medium Format Camera Types
Flatbed cameras are often referred to generically as
field cameras, flatbed cameras are light and portable enough to carry anywhere. In a flatbed camera, the two standards travel on a rectangular framework or "bed." The frame usually consists of a dual telescoping track that allows you to easily adjust the lens-to-film distance. Most flatbed cameras can be folded up into a compact, self-contained box for carrying. Potential limitation of field cameras is that not all of them accept interchangeable bellows--a major drawback if you work with very
The twin-lens reflex (TLR) camera features two objective
lenses using an identical
focal length. One of the lenses reflects the image in the viewfinder while the other image exposes the film The viewfinder is made up using a 45-degree angle mirror (a basis for the name reflex), a matte focusing display located at the camera's top, plus a surrounding pop-up hood. These dual objectives are joined, so that the composure reflected upon the focusing screen becomes exactly identical to what ends up on the film. Although, many cheaper TLRs are usually fixed-focus units. A majority of TLRs employ leaf shutters using shutter speeds as quick as 1/500th sec using a B settings.
