Note from Editor:
This is a joint effort by the members of various forums who enjoy Infrared photography. Thanks to everyone for their suggestions, comments, proofreading, lists, links, measurements, experiments and all round good fellowship.

Please PM Andrea B. on UltravioletPhotography.com with any corrections, additions or suggestions.

  • IR = infrared
  • UV = ultraviolet
  • UV/IR = ultraviolet and/or infrared

Our purpose for this IR Sticky is to collect some useful information about IR-capable cameras & lenses, filters, IR-lighting and camera modifications. We present it in the form of lists and links so that it can serve both as a guide for beginners and as a useful reference for more experienced users. The IR Sticky is not meant to be exhaustive, but if you think we have left something important out, please do contact the Editor.

What do you need to make a reflected Infrared photograph ?
  • IR-Capable Camera: IR light must be able to reach an IR-sensitive sensor.
  • IR-Capable Lens: IR light must be able to pass through the lens elements.
  • IR-Pass Filter: Visible & Ultraviolet wavelengths must be blocked.
  • IR Light: Sunlight or artificial source.
For Infrared photography, please keep in mind that you will be using your camera and lens gear outside the Visible range for which it was designed. So there can be some complications when shooting IR. Generally speaking, however, Infrared photography is easy and fun.

Taking this from the top....

The Camera
I think we can safely say that all recent digital DSLRs, Mirrorless and Compact cameras are IR-capable with modification although the finer points of IR-sensitivity of digital camera sensors is best discussed on a per-camera basis. Actual measurements of a sensor's IR sensitivity are not made available by camera manufacturers. So our knowledge here is gained the hard way - we mod a camera, shoot with it and list it in the IR Sticky if it works well for IR.

See the IR Cameras section for a list of IR-capable cameras contributed by interested users. Be sure to let us know what you are using so we can add it to the list.

Most digital cameras have an internal filter that blocks UV/IR to varying degrees. In the newest cameras this UV/IR-block filter is very strong and must be removed to enable IR photography. Newer cameras also may have a sensor-covering dust shaker mechanism which contains UV/IR blocking glass, so this type of dust shaker may be permanently removed during the modification. Some older cameras had weak internal filters and could shoot UV/IR without modification - the Nikon D70 being the classic example. A few brave souls modify their camera themselves, but most of us send the camera to a retail modification shop.

During IR modification the internal filter is typically replaced by an IR-pass filter glass or a clear full-spectrum glass of the same thickness. This is done to protect the underlying, fused Bayer (or other) filter & sensor layers and to ensure the correct register distance is maintained for focusing. Additional internal focusing adjustments might be needed. Modifying the camera with an internal IR-pass filter permits you to use the viewfinder for framing and focusing. Choosing instead an internal clear glass instead permits the camera to be used with any wavelength of external IR-pass filter, but you probably can no longer use the viewfinder depending on how dark red the filter is.

See the Camera Modification section for some links to retail modification shops and DIY articles.

The Lens
There's no predicting whether a given lens is IR-capable. Some lens coatings can block IR. Many lenses have a reflection problem in IR called a 'hotspot'. However, there are a large number of ordinary lenses which are IR-capable even though most all of them will have a chromatic aberration problem called 'focus shift' which must be dealt with. Fortunately, some extremely experienced IR shooters have provided us with an extensive list of IR-capable lenses that are hotspot free.

See the IR Lenses section for more info on IR-capable lenses, hotspot and focus shift.

The Filter
There are a wide variety of IR longpass filters and glass available. If you choose a shorter wavelength internal IR-pass filter (675 for example), then you can always use a longer external IR-pass filter (830nm for example) on the lens. But if your internal IR-pass filter is at 830nm, for example, then you can never shoot below that. We have lists of external filters below as well as some references to the glass from which they are made. This should help you choose a modification wavelength or a good external filter.

Please see the separate The UV/IR Filters Sticky for extensive filter information.

The Light
Most Infrared photography is done in the near Infrared band from about 700-1000nm. So sunlight is your friend when shooting IR outdoors. Indoors, you might want to use regular flash which produces plenty of IR or an IR-LED hotshoe attachment.

See the IR Lighting section for more information.

Please let us know of any interesting links you find.
To read and learn more about Infrared light and Infrared photography, visit these interesting websites and articles. Many of them have links to other IR info.

First the basics from the digital reference standard - Wikipedia. And a link to some cool IR history. Now the links. .
The IR Sticky was begun by Nikon users so there are a lot of Nikon comments. That, however, is simply historical accident. We are happy to add any comments received about any camera being successfully used for Infrared photography.

Although almost every unmodified camera can record some IR if you give it a long enough exposure, any camera will perform better in IR if its internal blocking filter is removed. Newer DSLRs and mirrorless cameras must be converted to use them for IR photography because manufacturers have increased the strength of the internal UV/IR blocking filters. Many cameras also have a dust shaker mechanism covering the sensor which contains UV/IR blocking glass, so this type of dust shaker may be permanently removed during the modification.

If you choose an internal IR filter for your conversion, you will have both the viewfinder and Live View available
for focusing. If you have decided on a full spectrum conversion in order to be able to make use of different external IR filters, then in sufficient light you can still use Live View to focus your IR shots.

Good IR Cameras
Here are some links and a short list of converted cameras which have been successfully used for Infrared photography. If your camera is not listed here, please contact the Sticky editor.

Do Not Convert: Sony RX100
The lens hotspots at the long end and when stopping down. However, when used with a Monochrome setting, the hotspot is less visible.

Do Not Convert: Nikon D700, D3, D3S, D3X, D4, D4S
Do not convert these Nikon DSLRs because they have an IR-LED self-diagnostic shutter monitor which can produce IR contamination of photos. The excess IR light from the shutter monitor will show up as a lighter area of flare, smear and discolouration in a photo. An exposure with low ISO and short speed might mitigate the IR contamination, but many shooting scenarios do not allow this. Because we do not know the wavelength of the IR-LED, we cannot offer any advice about which IR-pass filter might permit a workable conversion. Note that newer Nikon DSLRs having a shutter monitor - D7000/D7100, D600, D800/E - are convertible. Apparently their shutter monitor is of such a design that it causes no IR contamination. You can see the IR shutter monitor for the D3S on this Nikon Flagship Reliability page. Scroll down to Shutter Unit section.

OLD Nikon or Nikon F-Mount with CCD Sensor
The older DSLRs listed here have CCD sensors and are good candidates for IR shooting. Some of them are IR-capable (or UV-capable) without modification and make good DSLRs for UV/IR beginners who would like to get started with minimal expense. With an unmodified DSLR, exposures will be longer & noisier and using the viewfinder is not possible. The listed cameras are no longer manufactured, but can be found as resales in the used section of online retailers, in camera forums' sales boards, or on Ebay or Amazon.

Nikon DSLRs (old):
  • Usable unmodified: D1, D1H, D1X, D100, D2H, D50, D60, D80.
  • Usable unmodifed, but better if modded: D2HS.
  • Good unmodified: D70, D70S, D40.
  • Must be modified: D40x, D200
Fujifilm Finepix (old):
  • Must be modified: S3 Pro, S5 Pro
  • Pre-modified by Fuji: S3 Pro-UVIR, IS PRO. Both no longer manufactured, but available used.
Kodak (old):
When we first started the Stickies, we listed these cams as having UV/IR potential, but I don't know if they can be found anymore.
  • DCS 520, 560
  • DCS 620, 620X, 660
  • DCS 720X, 760C

We would like to thank Robert Reiser for his excellent work in compiling a world-wide list of camera converters which can be found here: Infrared Camera Conversion Service: The Complete Provider Overview

I will add some links below which we did not previously have, but I encourage you to please go to Robert's site to read more about the following conversion services and also about the 5 we previously listed above. .

A hotspot is a washed out, bright round area in the center of a photo which could be caused by one or more of the following:
  • IR reflection from the glass lens elements
  • IR-reflection from non-element lens parts
  • IR-reflection from metal filter mounts or step rings
  • IR-reflection off parts in the camera mirror chamber
  • Light leakage through the Viewfinder, body ports, lens windows.
Sometimes just the presence of an external filter will cause an IR hotspot. Hotspotting may vary by sample across a particular lens type. It certainly can vary by aperture, so be sure to test your lens for IR hotspotting at all apertures to learn its acceptable range for hotspot-free photos. Shooting directly at a light source can induce both hotspotting and other circular flare, but the hotspotting will occur even when shooting away from the light source. Additionally, hotspotting may vary by camera. Sometimes a lens hotspots on an FX sensor but not on a DX sensor, or vice versa.

Check for IR-reflective internal or external materials in your lens, filter mounts and step rings by IR-photographing them. If you suspect that a focus distance window on the side of lens is causing hotspots or flare because of light leak, simply tape it over. Experiment with closing the Viewfinder after composition - sometimes light can leak through it and ruin an IR or UV shot.

IR Focus Shift
Focus shift between the Visible & Infrared wavebands in a lens is a form of axial chromatic aberration that occurs because shorter, higher frequency Visible lightwaves refract more in typical optical glass than do longer, lower frequency Infrared lightwaves.

Such wavelength-induced focus shift is a topic of particular interest in IR photography when using an external IR-pass filter and a camera that has no Live View or that uses a very dark IR-pass filter. First you must focus the lens in Visible light before mounting the IR-pass filter. After mounting the filter you might have to adjust your initial focus if the lens has not been designed to bring the IR rays to the Visible plane of convergence. With a bit of trial and error you should be able to determine the proper correction and note it for future reference.

IR focus shift is less of a worry with an internal IR filter because during conversion the auto-focus can be adjusted a bit to compensate for IR for most lenses at most apertures. Focus shift is not problem at all when using Live View. Just remember that if you are using an external IR-pass filter with Live View you will need sufficient IR illumination to be able to use Live View.

Links to definitions:
  • Chromatic Aberration
    • Axial/Longitudinal CA: Different wavelengths (colours) focus at different distances from the lens because the lens refractive index varies along the optical axis by wavelength (dispersion). Axial CA causes colour fringing at bright/dark boundaries in the photo and may be reduced by stopping down.
    • Transverse/Lateral CA: Different wavelengths (colours) focus at different positions on the focal plane radially from the center because the lens magnification varies perpendicularly to the optical axis by wavelength (dispersion). Transverse CA causes problems outside the center of the photo and is not reduced by stopping down.
  • Spherical Aberration
    An optical distortion caused by increased refraction of light towards the edge of a lens.
  • Achromatic Lens
  • Apochromatic Lens
  • Superachromatic Lens
In photography, diffraction is the spread of light waves caused by their passage through a lens aperture. The narrower the aperture, the more the diffraction. In UV/IR photography, a key fact to note is that longer IR wavelengths spread more at a given aperture than shorter Visible or UV wavelengths. Thus IR shots are more prone to the effects of diffraction and UV shots less so.

So, for example, if you make a Visible light photo with a sensor & lens combo that begins to show diffraction blur past f/8, then you will have to open up your lens to f/5.6 (or larger) to shoot a reasonably sharp IR version of the same photo. On the UV side, you could stop down to f/11 (or smaller) and still stay sharp. The rule of thumb is that there is approximately a 1-2 stop aperture variation around the diffraction limit of a given sensor & lens combo.

When diffraction is recorded by a digital sensor, it shows up as a loss of sharpness in an image.

About the IR Lens List
For a lens to be on the IR Sticky Lens List, it must have at least one contributer who has either used it or tested it to confirm that the lens is IR-capable in some portion of the IR bandwidth. Our lists are by no means exhaustive, so please experiment and let us know of your discoveries.

As before note that the IR Sticky was started by Nikon users so the IR Lens List is rather Nikon oriented. Please tell us about your non-Nikon IR gear so that we can add it here.

Please Note:
  • IR-Capability ?
    The amount of IR-capability of the lenses on this list varies.
    We have tried to list some lenses that do not show hotspotting in IR
    or have only minor hotspotting at certain apertures or magnifications.
    Investigate before purchase!
  • F-Mount ?
    A few lenses on this list may not have Nikon F-mounts.
    Modification of the lens mount and the use of focusing helicoids and/or bellows
    may be necessary for use on a Nikon camera body.
    Investigate before purchase!
  • IR-Focus Shift?
    Most of the lenses listed below experience some degree of the IR-Visible focus shift discussed below.
    Lenses without such focus shift are noted.
    Investigate before purchase!

IR Lenses: Hotspotters
Please remember: Hotspots in IR may not be caused just by the lens alone, but by the combination of camera + lens + filter + light conditions. So the inclusion of a lens in this list does not automatically mean that it is useless for IR, but only that some user has rejected it for their IR photography. You may find that a lens listed here works well for you, or not. This list is by no means exhaustive. Remarks are basically as reported.

  • 10.5mm f? D Fisheye AF Hotspots on converted D2X. OK on some cameras.
  • 24-70 f2.8G AFS Sometimes works wonders in IR; sometimes it fails badly.
    Check for light leak through focus distance window.

  • 24mm f1.4G AFS Guaranteed IR hot-spotter.
  • 28-85mm f3.5-4.5 AF At f16.
  • 35mm f1.4G AFS Hotspots badly in IR.
  • 35mm f1.4 AIS Hotspots on converted D2X, especially with filters.
  • 35mm f1.8 Strong hotspot.
  • 35mm f? Series E Faint hotspot @f16 infinity.
  • 60mm f2.8G AFS Micro-Nikkor Huge hotspot problem in IR.

  • 70-210mm f4.0 AF At f11 or smaller at some focal lengths.
  • 35mm f/1.4 Art Strong central hotspot.
  • RX100 Hotspot less noticeable if monchrome setting used.
  • 17-35mm f2.8-4.0 Slight hotspot, but still usable.
  • 90mm f? MF Had hotspots on both my Fuji & Nikon cameras.
  • 12-24mm f4 If you like hotspots, this Tokina is very good at that!
  • IR and Lenses
    This article by Gisle Hannemyr lists many IR-capable lenses.
The typical on-board flash or hotshoe flash will provide enough IR light for most IR photography.
Here are a few links to other IR lighting options.
  • Digi-Slave IR-LED Ring Light
    Uses 24 IR-LEDs @ 850nm.
    This is listed simply as an example of an IR-LED hotshoe flash.
