What is a 135 single lens reflex digital camera?
3,35MM camera is only for the film camera, and now the mainstream is a digital camera, in the production of digital cameras, there is no 35MM camera called. If it is only for the film camera, then, because the 135 camera film area is small, for the washed out of the photo there is an upper limit, more than this limit, the screen will be blurred. For the photo of the enlarged area of ??the high demand can not only use the film area of ??the small 135 camera.
2,35mm film specifications for the 24mm × 36mm, this specification is the most widely used traditional camera film specifications, so in the photography industry to form a tradition, that is, as a reference, as many times in the marked metric length The unit "m" is also converted to the English length unit "feet" and is noted later.
We know that the focal length indicates the distance from the lens to the focal plane, that is, the distance from the lens to the film or the sensor. The precise definition of the focal length is "the distance from the focal point to the lens optical center". For digital cameras, the focal length is usually very small, which is due to the current digital camera commonly used image sensor specifications are very small - the diagonal length is usually not more than 25 mm, so the lens from the focal plane close, resulting in focal length Far less than the traditional 35mm camera is much smaller, the common 3x zoom optical lens is usually 6-18mm or 7-21mm or so. Coupled with different digital camera image sensor specifications are different, the lens marked on the real focal length of the number is also 7-21mm, in fact, converted to 35mm camera lens focal length is not the same. However, the real reason for marking the number of focal lengths with a 35mm camera is that most photographers can not understand why the lens focal length of a digital camera is so short that it can not understand the complex conversion relationship and convert the equivalent of 35mm camera lens focal length with this conversion relationship
135 single-lens reflex digital camera is full-frame (CCD, COMS or film size = wide 36x high 24mm) SLR camera.
Here's what is the 135 camera.
1,35MM camera is 135 camera, both of the same kind of camera call.
135 camera film frame width is 36x high 24mm, count the height and the upper and lower square hole height is 35mm.
This film originated in the late 19th century film film, and later it was Germany in 1924 (left and right) for the Lycra camera and the formation of industrial production, which is the initial use of 35mm film camera. Later, we recognized the 35mm film called 135 film, with 135 film camera called 135 camera.
