Actually, however, even using a tripod may result in image blur because of tripod vibration caused by mirror or shutter movement at the time of exposure. Automatically detects panning and then corrects camera shake only in one direction. For example, if you are shooting at focal length of 80mm and it is known that the efficiency of image stabilizer is 3 stops, it means that during handheld shooting at such focal length you can use shutter speed of 1/10 second which is exactly 23 times longer than the shutter speed 1/80 second needed to obtain sharp image in sufficient lighting conditions. Lenses with this focal length are often used as standard lenses, since they allow you to shoot almost the same wide range of scenes as lenses with focal lengths of 50-55mm, while providing a wider field of view. This is the smallest focal length at which an (ultra) fast-speed prime lens based on the double Gauss design did not prevent the flipping mirror from returning to its original position. The lens extended into the SLR's mirror box when mounted. As a rule, this class of lenses consists of high-speed models, however, there were also slow ones in the era of analog photography.

The lens barrel section holding the front lens group rotates to move the front group backward and forward during focusing. 50 and 55mm are the classic focal lengths of standard lenses for 35mm full-frame cameras, and one of the most popular. For this reason, a 1:1 ratio is often called "life-size". Incoming light is reflected twice on the mirror surfaces, resulting in compactness of the lens barrel and light weight relative to the focal length. The set typically consists of a 16-35mm ultra-wide angle zoom lens, a 24-70mm standard zoom lens and a 70-200mm telephoto zoom lens and usually represents the best constant-aperture zoom lenses in a manufacturer's lineup. Japan. This is also facilitated by the high speed of most standard lenses, as well as, as a rule, compact size and low weight (at least for lenses intended for amateur photographers). Price . As a result, pancake lenses are now also available in wide-angle and even short telephoto variations.
