So a standard 50 mm lens for 35 mm photography acts like a 50 mm standard "film" lens even on a professional digital SLR, but would act closer to a 75 mm (1.5×50 mm Nikon) or 80 mm lens (1.6×50mm Canon) on many mid-market DSLRs, and the 40-degree angle of view of a standard 50 mm lens on a film camera is equivalent to a 28–35 mm lens on ...

In photography, exposure value ( EV) is a number that represents a combination of a camera 's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance ). Exposure value is also used to indicate an interval on the photographic exposure scale, with a difference of 1 EV ...
In digital photography, the image sensor format is the shape and size of the image sensor . The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras ...
