Tokina SZ PRO 900mm f/11 Reflex MF CF Lens for Canon EF-M, Black SZPROMF90

The Tokina SZ 900mm PRO Reflex F11 MF CF is a super compact, fully manual lens, which adopt a catadioptric-type optical design. These lens features 900mm focal lengths, and is exclusively designed for APS-C mirrorless cameras. The Tokina SZ 900mm PRO Reflex F11 MF CF incorporates integrated mounts for Canon EF-M.Thanks to a catadioptric optical design this lens is very light weight and super compact. This product allows you to enjoy the world of super tele photography, and is a perfect option for users who are looking for affordable super tele photo lens.Rediscover advantages of mirror lenses, by using it with contemporary mirrorless cameras.We believe that the value and viability of mirror lenses should be reconsidered in contemporary photography. Therefore, we have renewed our lens technology and development. Our new mirror lens options will allow you to embark on a new tele photo journey.Easier FocusFocus assist functions like focus peaking will help to find the sharpest focus point.Less ShakingIn-build multi-axis advanced image stabilization systems of mirrorless cameras will make you forget about blurred images due to hand shaking.No Slow Shutter Any MoreNewest mirrorless cameras featuring advanced wide ISO settings can offer photographer choosing faster shutter speed with minimum pixel noises on the image.Super Compact Super Tele LensThe Tokina SZ 900mm PRO Reflex F11 MF CF is an ultralight and compact mirror lens. No need to carry a large camera bag any more. You can enjoy super tele photography casually and comfortably.Tokina's compact mirror lens design was realized by incorporating mirrors on the front and rear side of the barrel. In standard optical lenses, light passes through the lens and enters the camera sensor. However, in mirror type lenses, light enters the lens and reflects of mirrors twice before reaching the sensor. By "folding" the light path twice, the focal length shortens, which allows for a smaller lens design.Mirror lenses' optical system is known as a catadioptric system. NASA's Hubble Space Telescope and James Webb Space Telescope use this catadioptric system, albeit on a much larger scale.Improved Optical PerformanceBetter Suppression of Chromatic AberrationsTele photo lenses are prone to chromatic aberrations (CA) due to their complex optical design. To reduce CA, manufacturers incorporate additional color correction lens elements into the already bulky and heavy construction.On the contrary, mirror lenses mainly use mirrors combined with a few lens elements. This optical combination greatly suppresses chromatic aberrations. We went beyond this with the Tokina SZ 900mm PRO Reflex F11 MF CF by fully optimizing the optical configuration so that CA were further reduced.Low Level Flare and GhostingClassic mirror lenses are known for their weakness to flares and ghosting, which occurs when light finds tiny gaps to leak directly onto the sensor.The Tokina SZ 900mm PRO Reflex F11 MF CF is built with a shielding ring
