Designed to block both ultraviolet and infrared spectra, while allowing visible light to cleanly pass, the Formatt Hitech 49mm Firecrest UV IR Cut Filteris a specialty filter that helps to achieve accurate and precise colors with digital sensors. This unique filter also features a 15-layer Firecrest coating, which further serves to minimize surface reflections and maintain light transmission for consistent color accuracy and image acuity.

Due to sensors' increased sensitivity to infrared light, false colors can occur when photographing in difficult lighting conditions. This filter helps to only pass visible wavelengths in order to avoid unwanted color shifts for greater color accuracy and image clarity. This filter is constructed from optical glass for maintained image quality and is set in an aluminum filter ring. The SuperSlim ring measures 5.5mm-thick and its slim design helps to minimize the likelihood of vignetting. This filter features front threads to permit stacking of additional filters or the attachment of a lens cap.

UV IR cut filter blocks wavelengths at both sides of the visible spectrum in order to achieve a more pure transmittance and greater color accuracy.

The 15-layer Firecrest coating has been applied directly to the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is water- and scratch-resistance for greater overall durability.

Firecrest coating attenuates UV and IR contamination, as well as surface reflections, for consistent light transmission and acuity.

Optical glass is used in order to maintain clear image quality with high contrast and color fidelity.

The aluminum alloy SuperSlim filter ring measures 5.5mm-thick and features front threads for stacking additional filters.

Related Questions and Answers

Q: 1. Does this exhibit any tinting at wide angles? (I have a Heliopan UV/IR cut filter which (as advertised) starts to tint green at wider angles (at 24mm & wider).)

A: Unfortunately it does at wide open, almost always, however even zooming in slightly removes the vignetting, I have two of them, I only use it on the Canon 70-200 it is not suitable on my 24-70, the real problem is the vignetting doesn't show up in the viewfinder or live view

Q: 2. Can this filter be used with a VND filter to cut the IR ? Would you put this filter first on your lens or on top of all others?

A: Yes, filters are stackable on the Ice 82mm UV/IR Cut Filter as long as they are 82mm in diameter.

Q: 3. Can I use this circular filter placed on my lens and carry on a mattebox with square ND filters to avoid IR input? Or will it be better to buy square IRND filters for mattebox? I have little budget and I don't know what a better option.

A: If the mattebox fits on the camera lens with filter in place you could do it that way.

Q: 4. Does ir cut only serve to reduce red from sunlight or is this also necessary in artifificial light like LED?

A: LED white lights typically remove unused spectrums to save on power so the difference under artificial light should be minimal. The largest gains will be under sunlight and UV/IR specific lighting. Unless the camera is full spectrum modified you will likely see very little difference under any light but almost none under modern artificial lighting. I would not buy an IR cut filter unless the camera is full spectrum modified as your camera already has one built in and UV filters are much less expensive. HTH.

Q: 5. Is this the filter to use for Leica M8 to not get purple blacks? In other words the same as what Leica supplied for M8 buyers?

A: The B+W UV-IR Cut #486 MRC Basic Filter (49mm) blocks 88% of ultraviolet light waves and 95% of infrared light waves.

Q: 6. Does this filter safely block potentially harmful light for direct solar photography? In other words, does this UV and IR cut filter serve the same purpose as a solar filter (other than darkening the image) for taking photos of the sun?

A: No, this filter is NOT safe to use for Solar photography.

Q: 7. What is the IR cutoff? What wavelengths does the filter actually allow to pass through?

A: The Ice 77mm UV/IR Cut Filter cuts out UV Rays below 390nm, and cuts out IR Rays above 750nm. The filter has 99.4% light transmission between 400-700nm.

Q: 8. Hello, I've read a review telling that when using a UV/IR filter on WIDE Angle Lenses the image can be compromised: the interference varies with the angle of incidence of the light on the glass. This renders this filter unusable with wide-angle and even normal focal lenses, resulting in a greenish gradient from the center to the corners. - This was posted for the 72mm version of another brand's filterQ: Has someone else experienced this problem on Full Frame or APS-C DSLRs with Wide Angle Lenses like 16mm ?Thank you very much in advance!

A: UV/IR blocking filters work ideally for lenses with an aperture angle up to 60. The principle of such an interference filter is an aperture angle-dependent color influence that is dictated by physical principles, and as the angle of the incident light increases it drifts towards blue, i.e. for wide-angle lenses, from an aperture angle larger than 60, the color reproduction at the edge of the image tends to lean towards bluish.

Q: 9. Hello. Does this filter have the same difficulty with wide-angle lenses that most multi-coated cut filters have? I.e., inconsistent, off-axis effectiveness/banding beyond ~ 60 degree FOV. Thanks in advance!

A: Yes, this Ice 77mm UV/IR Cut Filter has the same wide angle issues many filters have. The IR filtration makes no difference, as far as the wide angle effectiveness goes.

Q: 10. Has anyone combined a Hoya 77mm uv and ir cut filter with a circular polarizer on a 24-105 canon l series is lens using a 5D Mark III, if you have what were the results? Thank you very much before I buy the pair of filters.

A: We are not aware of any issues that combo would create.
