Related Questions and Answers

Q: 1. 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: 2. 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: 3. Does this include a t-mount adapter, or is that purchased separately?

A: The Tokina SZX 400mm f/8 Reflex MF Lens for Canon EF has a Canon EF mount. It is not a T mount lens.

Q: 4. Has anyone used this lens on a 90D or another camera that doesn't have focus peaking or vibration control? If so, were you able to get reasonably sharp photos without camera shake being an issue?

A: It's definitely going to be a bit more difficult focusing with a 90D or DSLR that doesn't have stabilization or focus peaking. I would recommend using a tripod and a shutter remote to maximize stability. Even with focus peaking and stabilization, the lens still requires critical focusing.

Q: 5. Could you use this for photographing the moon, or non-moving wildlife?

A: Yes, you will have to bump up your iso to compensate for the small aperture of f/8.

Q: 6. Will focus peaking work when mounyed to a OLY OMD EM1 mkII?

A: Focus Peaking will work on the Olympus OM-D E-M1 Mark II with the Tokina SZX 400mm f/8 Reflex MF Lens for Micro Four Thirds.

Q: 7. Is it necessary to post-produce a lot (sharpening, contrast, etc) your original file from this lens to get something good ?

A: It would really depend on how the focus and exposure was done in camera.

Q: 8. I am planning to order one for my d750. Will the f-mount come with it Fit a z mount? Or is there a separate z mount adapter available?

A: The lens is a Nikon F mount lens. If you want to use it on a different camera than the D750. Like a Nikon Z mount, you will need to get an adapter. This is one option for a lens adapter, Nikon FTZ Mount Adapter BH #NIFTZ • MFR #4185 https://bhpho.to/37kPGgs Note, the lens is manual only and it is not full frame. Used on your D750, it will crop the image by 1.5 times. And you will lose a lot of resolution.

Q: 9. Have a Nikon D3100. Would this one work for it? Do I need something else? Additionally, is this one better than the vivitar 500mm? Which one is better for landscape photos, or moon photos? or wildlife (say, birds) from afar?

A: To use this lens on the Nikon D3100 in order to shoot subjects that are very far, the Vello T-Mount Lens to Nikon F-Mount Camera Lens Adapter, BH # VELANFT is needed. Although the optical quality is better on this lens, it would offer less range versus a Vivitar 500mm T-mount lens. https://bhpho.to/2KGl6ow

Q: 10. 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.
