The Tiffen 72mm T1/2 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 72mm T1/2 IR Filter is used, near-infrared light waves beginning at 680nm are blocked by approximately 45%. Infrared light waves at higher frequencies are further impeded until nearly flat attenuation is achieved at 775 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 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, and then mounting to precision metal rings.

  Related Questions and Answers

  Q: 1. Is this filter compatible with fujifilm x100V lens?

  A: Yes, this filter is compatible with the X100V.

  Q: 2. Does this sit furthest from the camera or closest to the camera when pairing with a Variable ND filter?

  A: It really doesn't matter but typically a UV filter goes on the lens first.

  Q: 3. How does this card compare to the old "Synology E10G18-T2 Dual-Port 10 Gb/s PCIe Expansion Card"? When using it with DS 1819+ do I want one 10G port and cache drives or just two 10G ports? What's the benefit of two 10Ge ports? I will be using with a Mac. Thoughts?

  A: Cache drives and 10Gb/s ports have different purposes and which will be more beneficial is a matter of use case.

  Q: 4. Is WD 1TB Black SN750 NVMe M.2 SSD working with this card?

  A: Yes, this will work with the WD 1TB black NVMe Drive.

  Q: 5. Is this compatible with DS1821+? I understand this unit already has 2 M.2 for it already but What can it hurt to cache more?

  A: The DS1821+ is not on the list of compatible NAS enclosures for the Synology E10M20-T1 Combo Adapter Card.

  Q: 6. I just bought a 60 mm Fujifilm macro lens and it has a bayonette mount at the front. Are there any protective filters that fit it (39 mm)?

  A: I don't have this particular lens, but from looking at the spec sheet it appears that a regular 39 mm lens filter would work. I have used various sized filters for various Fuji lenses without problem. If you find that it doesn't work, b and h has great return policy, which I have used several times. Hope this helps.

  Q: 7. Is this compatible with the DS1819+?

  A: Yes, the Synology E10M20-T1 M.2 SSD & 10GbE Combo Adapter Card BH #SYE10M20T1 is compatible with the Synology DS1819+.

  Q: 8. Would a Crucial 4TB P3 Plus NVMe PCIe 4.0 M.2 Internal SSD card work with this?

  A: Synology has not listed any non-Synology drives on their compatibility list for the E10M20-T1 M.2 SSD & 10GbE Combo Adapter Card, but any PCIe M.2 2280 or 22110 drive should work.

  Q: 9. Does the lens hit the filter in macro mode?

  A: I using it with lens hood (lens hood comes with adaptor), so it does not.Without adaptor - it possible that it can hit.

  Q: 10. Is it compatible with DS1621+?

  A: Yes, it should be compatible. https://www.synology.com/en-us/products/E10M20-T1#specs
