The SZX 400mm f/8 Reflex MF Lens is a 400mm catadioptric optical design super telephoto lens with a fixed f/8 aperture, which offers a compact alternative to standard telephoto lenses. It's lightweight and compact design fits easily inside a pocket or small bag and is suitable for travel, wildlife, and outdoor photography.

• Manual focus catadioptric optical design telephoto lens with fixed f/8 aperture, which is compatible with select camera focus peaking systems and in-body multi-axis advanced image stabilization systems.
• Multi-layer anti-reflection coating for efficient light intake and reduced flare, plus high-reflectivity silvered coating and a protective antioxidant layer on the back side of mirrored surfaces for long performance life.
• Minimum focusing distance of 45.3" and magnification 0.4x can capture small objects, while the 400mm focal length reduces the possibility of casting a shadow on the subject.
• Catadioptric design and construction creates a smooth and unusual donut-shaped bokeh.
• Wide focus ring provides smooth rotation range of 270°.

Extending the effective focal length of the Tokina SZX 400mm f/8 Reflex MF Lens, the 2x Extender increases the lens's magnification by 2x for a narrower field of view. In effect, this extender doubles the effective focal length of the lens, turning your 400mm lens into an 800mm optic.

Related Questions and Answers

Q: 1. What is the actual weight of the lens (including the rear mount adapter)?

A: The following unit weighs in at 0.80 lbs.

Q: 2. Do this need and/or come with an adaptor for Fujifilm. Is this lens auto focused, or totally manual focus?

A: This lens comes with an adapter and is manual focus only.

Q: 3. Regarding previous question between vivitar 500mm and this one, how much is the difference on optical quality, when saying this one is better? And how much distance difference does the 100mm make?

A: This lens is multi-coated against lens flare and reflections, which makes it better than the Vivitar 500mm T-Mount lens. Having the added range on the Vivitar lens may not seem like much, but it could help when you need to get a bit closer to the subject.

Q: 4. If I use this lens on a D500 that has a cropped sensor, will the true focal length be somewhere around 600MM ?

A: The angle of view of the Tokina SZX 400mm f/8 Reflex MF Lens for Nikon F on the D500's crop sensor would be roughly equal to the angle of view of a 600mm lens on a full-frame image sensor.

Q: 5. Last question, I think. I currently use, for "distance" photo, a 55-200 Nikkor. Going from this to this 400mm, is it too much of a difference regarding quality and distance? (not sure how much difference there is between 200 and 400mm). Additionally, in image the lens seems "small", when comparing to vivitar 500mm. Is it that size or you have to "open" it?

A: This lens would be double the magnification of your 55-200mm at the 200mm end. This lens would be more compact that the Vivitar 500mm lens. Please feel free to reach out to us directly via Live Chat or e-mail to askbh@bhphoto.com with any other questions you may have.

A: Yes, this Tokina SZX 400mm f/8 Reflex MF Lens when used with its 2X Extender would make the maximum aperture set for f/16.

Q: 8. will the 2x extender drop the aperture say make the f/8 into a f/16?

A: Yes. A 2x teleconverter loses 2 stops of light, so an f/2.8 lens drops down to a wide aperture of f/5.6.

Q: 9. I don't see the Nikon D700 listed under the compatibility list even though it uses the F Type lens...is the D700 not compatible for some reason, or only with limited function unlike the other models listed?
