Micro 4/3 lens
 Micro 4 / 3 lens System - is a standard created by Olympus and firms Matsushita (Panasonic) for parallel development and production of compatible digital cameras, camcorders and optics to them. The standard was first announced in Tokyo on August 5, 2008. The standard includes a bayonet (with an electronic interface), the geometry of the working chamber of the segment and the matrix, a number of other parameters. The standard is derived from the known standard 4:3 and is a modification. It is not an open standard because it does not satisfy the requirement of free use of any manufacturer. Sensor size remains the same as in the standard 4:3. As the name implies, this standard is intended to reduce the size and weight of digital cameras and camcorders with interchangeable lenses by reducing the thickness of the body without loss of quality of the images. An important advantage of SLR cameras is the ability to change lenses. Since the mechanism of the mirror is located between the shutter and lens, the desired working distance becomes quite large. This standard excludes from the chamber construction hoist mirrors, and the associated mirror viewfinder. For this reason the working distance is reduced by half compared to the standard micro 4 / 3 lens (from 40 mm to 20 mm), thickness of the camera body is reduced accordingly. Instead uses an electronic viewfinder, mirror or viewing mode on the screen. This has several advantages, such as 100 -% compliance with future image observed through the viewfinder image enhancement observed image in low light conditions, the ability to output a large number of proprietary information in the field of view of an electronic viewfinder.

It can be used as kit lens, portrait lens, landscape lens, macro lens (including the rings). The lens in the embodiment of screw in the M42 costs about 25-75 dollars. Since this lens is fairly inexpensive, then it often makes eyeglass monocle (Lensbaby). More>>
Industar 22 lens history
Standard lens with coated optics. Fitted with iris diaphragm.
Produced for the first rangefinder cameras such as "Zorki" and the suffix "V" ("Y", "F-1") - for photographic enlargers. Was the standard lens for the first SLR Zenith.
Had different design options, including a folding option, similar to the lens Leitz Elmar (3,5 / 5 cm), 1).
In the late 1950s and was replaced by the recalculation, a higher quality lens of the same scheme - Industar-50.
