Tokina SZ 300mm PRO f/7.1 MF Mirror Lens for Fuji X-Mount

The Tokina SZ 300mmPRO Reflex F7.1 MF CF is a super compact, fully manual lens, which adopt a catadioptric-type optical design. These lens features 300mm focal lengths, and is exclusively designed for APS-C mirrorless cameras. The Tokina SZ 300mmPRO Reflex F7.1 MF CF incorporates integrated mounts for Sony E, Canon EF-M, and Fujifilm X.

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 Focus

Focus assist functions like focus peaking will help to find the sharpest focus point.

Less Shaking

In-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 More

Newest mirrorless cameras featuring advanced wide ISO settings can offer photographer choosing faster shutter speed with minimum pixel noises on the image.

Smaller Than a Cup of Coffee

The Tokina SZ 300mmPRO Reflex F7.1 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. Our 300mm variant fits in one's pocket and is smaller than a tall size cup of coffee.

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 Performance

Better Suppression of Chromatic Aberrations

Tele 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 300mmPRO Reflex F7.1 MF CF by fully optimizing the optical configuration so that CA were further reduced.

Low Level Flare and Ghosting

Classic 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 300mmPRO Reflex F7.1 MF CF is built with a shielding ring (baffle) which prevents light leaking directly onto the sensor. This suppresses flares and ghosting, and maintains contrast even without a lens hood under general shooting conditions.

*When shooting in conditions with severe backlighting, attaching the hood is recommended.
