The flat dark earth Trijicon RM05 RMR Reflex Sight 9 MOA Green Reticlefrom Trijicon RM05 RMR Reflex Sight 9 MOA Green Reticleis an unmagnified targeting device that features a 9 MOA green dot aiming point, battery-free auto-adjusting reticle illumination, and lightweight yet durable construction. The Ruggedized Miniature Reflex (RMR) has a forged aluminum housing with a wear, corrosion, chemical, chip, and scratch-resistant Cerakote ceramic coating. For additional reliability when paired with a heavy caliber pistol or rifle, the RMR has a tempered glass window and robust o-rings capable of maintaining their seal to a depth of 65 ft.

Trijicon's battery-free illumination system employs a tritium phosphor lamp and fiber optics to automatically adjust reticle brightness depending on ambient lighting conditions - day or night, indoors or outdoors. Impact point correction dials with 1 MOA audible clicks and a parallax-free multicoated sighting window make the RMR well-suited for close-range targeting atop almost any firearm. An array of optional RMR mounts enable the reflex sight to be rail-mounted or paired with a pistol, shotgun, or ACOG weapon sight.

Related Questions and Answers

Q: 1. So what is the MM equivalent for a Fujifilm XH-1 or XPro-3?

A: The Fuji cameras have a 1.5 crop factor, so this lens will have an angle of view similar to a 600mm lens. It will still be a 400mm magnification.

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. 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: 4. 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: 5. Does this lens come with a protector filter as showed in the photo of it on this page?

A: The Tokina SZX 400mm f/8 Reflex MF Lens does not come with a filter but it can use any 67mm filter such as this Hoya: https://bhpho.to/3xlGMt1

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. 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: 8. Can the lens hood be reversed and stored on the lens?

A: The Tokina SZX 400mm f/8 Reflex MF Lens for Nikon F's lens cap cannot be reversed and stored on the lens.

Q: 9. 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: 10. I bought this lens with the f mount adapter, but I'd like to use it with my Canon EF camera. Where would I buy the EF adapter?

A: The Tokina TA0012 SZX T-Mount Adapter for Canon EOS, BH #TOTA0012, allows the Tokina SZX 400mm f/8 Reflex MF Lens for Nikon F to mount on a Canon EF camera.
