The Tiffen 82mm 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 maximise 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 colour shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.
When the Tiffen 82mm 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 colour shifts are prevented or minimised, which preserves colour 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 colour 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.
- Designed for use with CCD or CMOS sensors to filter out near-infrared and infrared light pollution that cause colour shifts frequently associated with high-definition recording
- Blocks near-infrared light waves beginning at 680nm by approximately 45% until nearly flat infrared attenuation is achieved at 775 to 800nm
- Constructed from Water White glass for increased optical clarity
- No dichroic coatings to further ensure colour accuracy
- 1.41x filter factor reduces exposure by 0.5 stops
- Thin filter ring helps to prevent vignetting
- Plastic filter case for storage and transport

Australian Shipping Via DHL
DHL now offer a great express shipping service to Australia from New Zealand. We are proud to be able to offer overnight shipping to main cities on the east coast of Australia. These main centers include:
Whilst this service is extremely efficient and will be delivered overnight 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it did not arrive overnight, it will most likely be delivered by the next day.
While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).
If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.
Please Note: Shipping via DHL is not available to PO boxes and/ or parcelboxes etc.
