- Q: What is a 135 single lens reflex digital 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
