The Tiffen 4 x 5.65" T1 IR Filter is a near-infrared to infrared control filter that is designed for digital cinematography. Many digital motion-picture cameras are designed to maximize their ability to capture red hues, and in that process near-infrared or infrared contamination may occur. If the proportion of near-infrared or infrared light that reaches the sensor of a digital cinematography camera becomes too great, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.

When the Tiffen 4 x 5.65" T1 IR Filter is used, near-infrared light waves beginning at 680nm are blocked by approximately 55%. Infrared light waves at higher frequencies are further impeded until nearly flat attenuation is achieved at 725 to 800nm. This process helps to ensure that the light that falls on the camera's sensor is limited to the visible spectrum. Potential near-infrared or infrared color shifts are prevented or minimized, which preserves color accuracy throughout the frame. While a Tiffen T1/2 IR Filter that blocks infrared light waves down to 775 nanometers is sufficient for many cameras, others may have sensors that require a higher degree of near-infrared and infrared control, such as that provided by a Tiffen T1 IR Filter.

This filter is constructed from Water White glass for increased clarity as well as color fidelity. It is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch.

  Q: 1. Will this fit the Fujifilm X-T4?

  A: Yes, the Think Tank Photo EP-F Hydrophobia Eyepiece fits the Fujifilm X-T4 camera as well as the X-H1, X-T3, X-T2 and X-T1.

  Q: 2. hi will this gripp fit fujifilm xt20?

  A: Unfortunately this grip is not compatible with the XT20.

  Q: 3. Does this work with nikon 7000 and sb 800 flash?

  A: Yes, however if you utilize the flash control "Commander Mode" function of the D7000 you don't actually need it. Check your camera's user manual for more information.

  Q: 4. Since this unit will not work fully with my Nikon SB 28 DX, then what would be the best remote brand and model that would operate my flash remotely? I would imagine that it would have to have a receiver component that my remote Nikon flash plugs in to, right?

  A: A compatible radio trigger for use with your SB-28 DX is the Vello FreeWave LR Wireless Flash Trigger and Receiver Kit, B&H # VERFWLR. You would still have to walk over to the flash to control it manually in terms of light output, but it would offer you wirelessly triggering up to 600 ft. Please see the image below for reference.

  Q: 5. Is this compatible with Nikon Z6 and Z7 bodies?

  A: I just tried on my Z7 with two Nikon R1 ring flashes. It worked perfectly. Very annoyed with no way to trigger remote flash from Z7. Not sure I like the twist-tight onto hot-shoe. Nikon flash's flip-tight is much better.

  Q: 6. will this fit an xt-20?

  A: I do not think it will fit, however, there is a short video on you tube by Bjorn Sozumschein of an ocular adapter that may have been made by him. Look under T-T20 eyecup. Hope this helps.

  Q: 7. Will EP-F fit the X-H2s?

  A: Yes, the Think Tank Photo EP-F Hydrophobia Eyepiece for Fuji X-H1, X-T3, X-T2, X-T1, GFX-50s is compatible with the FujiFilm X-H2s.

  Q: 8. Does this fit on the Fujifulm X-T30?

  A: Unfortunately this grip is not compatible with the Fuji XT30.

  Q: 9. I have the graphite Fuji XT-1. Is there a grip out there that matches mine?

  A: .vello BG F1is a very good alternative for fuji XT 1 graphite silver edition also I m using it works perfectly fine thank you BH photo

  Q: 10. WILL THIS ALSO FIT THE NEW Fujifilm X-T2 ?

  A: I asked Fujifilm (the technical department). They told me that each model is specific in terms of the functioning of the battery grips.
