- Own research.
Typical characteristics of mirror (reflex) lenses
- Catadioptric system consisting of curved mirrors and optical glass;
- Much shorter, lighter and less expensive designs than conventional super telephoto lenses;
- Outstanding correction of chromatic aberrations;
- Since the aperture is fixed, neutral density filters are used to obtain a smaller aperture;
- Doughnut-shaped out-of-focus highlights.
From the editor
The lens was produced by the Lytkarino Optical Glass Plant (USSR).
Notes
- "МТО" is an abbreviation for "Максутова ТелеОбъектив", which means "Maksutov's Telephoto lens", or "Менисковый ТелеОбъектив", which means "Meniscus Telephoto lens".
- Dmitry Dmitrievich Maksutov (1896-1964) is a Soviet scientist, optician, corresponding member of the USSR Academy of Sciences (1946). Inventor of the meniscus optical system bearing his name, which is now widely used in telescope construction.
- The lens has an interchangeable mount that is mechanically identical to the T2 interchangeable mount. In the USSR, the following interchangeable mount adapters were produced: "КП-А/42" (T2 - M42x1/45.5), "КП-А/39" (T2 - M39x1/45.2), "КП-А/К" (T2 - Pentax K), "КП-А/Н" (T2 - Nikon F). "КП" is an abbreviation for "Кольцо переходное", which means "Adapter ring".
