Related Questions and Answers

Q: 1. What is the total length and weight with the adapter?

A: The length of the the Tokina SZX 400mm f/8 Reflex MF Lens for Canon RF with the included mount adapter would be 3.43 in (87 mm) in length. The mount adapter by itself is 0.4 in (10 mm) in length.

Q: 2. 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.

Q: 3. For the MFT mount, does this 400mm with the 2x extender make this an equivalent of 400mm x 2 (extender) x 2 (MFT crop)?

A: Yes, using the Tokina SZX 400mm f/8 Reflex MF Lens with 2x Extender Kit for Micro Four Thirds on a micro 4/3rds camera is like a 1600mm lens.

Q: 4. Can the focal length of this lens be increased with a teleconverter?

A: This may be used with teleconverters that have no optical tube in their design, but not traditional teleconverters (such as Nikon's own 1.4x and 2.0x) that have them.

Q: 5. I just got this lens for an Olympus EM1-ii. Can't seem to get the focus peaking to work. Works fine with the one other manual focus lens I have. Is there some limitation with being 400mm or f/8?

A: According to Olympus, they state this must be an isolated lens issue. There is no in-camera reason for lack of focus peaking. You simply need to customize a button to focus peaking usage. Tap the selected customized button to turn on focus peaking, and tap the button again to turn off the focus peaking feature. If there is still no focus peaking, then it is really a lens issue as focus peaking depends on contrast to work; no electrical lens contacts are needed.

Q: 6. How does this lens perform for dark sky photography being f8? Thank you.

A: If you are looking for a telephoto lens to only capture a small portion of the night sky, then the Tokina SZX 400mm f/8 Reflex MF Lens for Sony E may be used for your planned usage needs, regardless of the lens' aperture. Usually, when photographing the sky at night, you are not using your aperture for exposure needs as you would not notice depth of field differences when photographing the sky focused at infinity. To control your exposure, most often your shutter speed will be your main exposure component (often using BULB mode).

Q: 7. How good is the image quality?

Q: 8. Does this come with a protective case?

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?

A: Although the manufacturer has not tested the Tokina SZX 400mm f/8 Reflex MF Lens with 2x Extender Kit for Nikon F with the D700, there should be no issue using them together.

Q: 10. Is the mount adapter included ?

A: Tokina SZX 400mm f/8 Reflex MF Lens with 2x Extender Kit for Nikon Z comes with a mount to use it on Nikon Z cameras.
