Short answer: An infrared-converted camera is usually the better choice for moving wildlife, action and handheld work. Nikon’s nature guide says a stock camera fitted with a 720nm filter may need 30–90 second exposures even in bright sunlight, so motion is limited to subjects that remain still. A removable filter is the better low-commitment way to experiment, particularly with a full-spectrum-converted body. Choose a dedicated 720nm or 850nm conversion when you want a consistent monochrome workflow; choose full spectrum when you need to switch among infrared wavelengths.
The practical answer for wildlife photographers
The deciding factor is not simply image style. It is whether your camera can collect enough infrared light quickly enough to freeze the animal. A normal DSLR or mirrorless camera contains an internal hot mirror or infrared-cut filter designed to suppress infrared wavelengths. Adding a dark external infrared filter in front of the lens therefore leaves very little usable infrared reaching the sensor.

In bright sun, Nikon reports that an unconverted body behind a 720nm filter may require exposures of 30–90 seconds. That can work for a stationary tree, landscape or animal that is genuinely motionless, but it is unsuitable for a walking mammal, a flying bird, breathing fur, moving leaves or handheld shooting. The long exposure is the central weakness of the stock-body approach.

The sensor can then receive infrared efficiently, allowing a workflow much closer to ordinary photography. A full-spectrum conversion goes further by leaving the camera able to record a broad range of wavelengths; external filters then determine whether you shoot visible light, 590nm, 665nm, 720nm, 850nm or another band.

How the three setups differ
| Decision axis | External IR filter on a stock body | Infrared-converted body | Full-spectrum-converted body |
|---|---|---|---|
| Wildlife movement | Usually poor in daylight because the stock IR-cut filter leaves very little IR; long exposures blur movement. | Best for action and handheld work because the internal blocker is removed or replaced. | Best when fast work and wavelength flexibility are both priorities. |
| Commitment | Removable and reversible. | Permanent modification to that body. | Permanent modification, with filters determining the band used. |
| Focusing and composition | Dark filters can block the optical viewfinder; use live view or focus before fitting the filter. | Conversion can include IR autofocus calibration; live view or an electronic viewfinder shows the IR scene. | Same conversion considerations, plus filter changes. |
| Look | Mostly determined by the filter wavelength; 720nm is a classic monochrome starting point. | Dedicated wavelength gives a consistent workflow. | 590, 665, 720, 850nm and other filters allow multiple looks. |
| Cost path | Lowest initial cost if you already own a compatible camera, but slow exposures can make the setup frustrating. | Conversion service plus the donor body; better field usability. | Highest accessory burden because you need external filters, but widest creative range. |
Why a filter on a regular camera is so slow
The internal IR-cut filter is still in the light path
Digital cameras are built to record visible light accurately, so their internal filter suppresses infrared before it reaches the sensor. A 720nm external filter blocks most visible light and transmits infrared above roughly that wavelength, but the camera’s own blocker remains in place. The combination creates a very small usable signal.
That is why fitting a 720nm filter does not turn a standard camera into a fast infrared camera. Nikon’s guide, accessed October 16, 2026, describes 30–90 second exposures in bright sun with a stock body and a 720nm filter. The exact exposure depends on the camera, lens, scene and light, but the practical consequence is clear: this is a static-subject technique, not a normal wildlife action setup.
What those exposures mean in the field
- Any movement during a 30–90 second exposure can produce blur.
- Handheld shooting is effectively impractical at those exposure times.
- A tripod can keep the camera still, but it cannot freeze an animal that walks, turns its head or flaps its wings.
- Moving foliage can also soften the frame, even when the animal is relatively still.
A stock body with a removable filter is therefore best treated as a learning and experimentation path. It can demonstrate infrared rendering and work for static subjects, but it is a poor solution if your main goal is responsive wildlife photography.

What an infrared conversion changes
Removing or replacing the internal blocker
A conversion service removes or replaces the internal hot mirror or IR-cut filter. With that restriction removed, substantially more infrared reaches the sensor. The camera can then use much shorter exposures than the stock-body-and-filter combination, making handheld work and moving subjects realistic.
A dedicated infrared conversion installs a fixed spectral response. For example, a 720nm conversion is designed around the classic infrared band, while an 850nm conversion emphasizes a stronger monochrome rendering. The body becomes a specialist tool: faster and more consistent than a stock body with an external filter, but no longer reversible for ordinary visible-light photography unless you use another camera.

Focus calibration matters
Infrared light does not focus at exactly the same point as visible light. Nikon notes that photographers must compensate for this visible-versus-infrared focus difference. Conversion guides therefore advise recalibrating autofocus for infrared focus shift.
Do not assume that every camera will autofocus correctly after conversion. Ask the converter for model-specific calibration information and confirm which autofocus modes are supported. A camera may focus acceptably in one mode or with one lens and miss focus in another.
Recommended Free Tools
Live view and electronic viewfinders reduce guesswork
A dark infrared filter can make an optical viewfinder nearly unusable on a stock body. Live view or an electronic viewfinder can show the infrared scene after the camera has been converted, making composition more practical. On a stock body, you may need to compose and focus before fitting the filter, then avoid disturbing the setup.
Full-spectrum conversion: the flexible option
A full-spectrum conversion also permanently removes the internal blocking filter, but it does not lock the camera to one infrared wavelength. You select the band with an external filter. This makes one body adaptable to several creative and documentary looks, but it adds handling and accessory requirements.
Full spectrum is the strongest choice when you want to move between visible-light work and several infrared bands using filters, or when a project may evolve. It is less convenient when you want to grab the camera and shoot quickly because each wavelength change requires a different filter and a corresponding white-balance and processing workflow.

Choosing an infrared wavelength
Kolari documents 550, 590, 665, 720 and 850nm conversion options. The following descriptions apply to the named bands in its guidance and are useful when deciding between a fixed conversion and a full-spectrum body.
| Wavelength | Typical rendering described in the guidance | Best fit |
|---|---|---|
| 550nm | Available conversion option. | Choose when you specifically need this band and have a defined processing goal. |
| 590nm | False color. | Projects that want an intentionally color-shifted infrared appearance. |
| 665nm | False color plus black-and-white contrast. | Photographers who want the option of color effects or a strong monochrome conversion. |
| 720nm | Classic contrast and dynamic range; Nikon calls the Hoya R72 a popular starting filter. | A conventional infrared look and a straightforward monochrome workflow. |
| 850nm | Strong monochrome. | High-contrast black-and-white infrared when color is not a priority. |
These labels describe the broad visual direction, not a guarantee for every subject. Foliage, sky, fur, moisture and the camera’s spectral response all affect the final file. A full-spectrum body lets you test several bands; a fixed conversion reduces decisions and makes the result more repeatable.
Which setup fits your wildlife project?
You photograph moving animals regularly
Choose an infrared-converted mirrorless body, preferably one with live view or an electronic viewfinder and documented infrared autofocus calibration. The conversion removes the stock camera’s main bottleneck, and the electronic display lets you compose through the infrared scene rather than guessing through a blocked optical finder.
Check the converter’s notes for your exact camera model and lenses before committing. The existence of an IR conversion does not by itself prove that every autofocus mode will work for wildlife distances or every lens design.
You want to test infrared with minimal commitment
Start with a removable 720nm filter such as the Hoya R72 on a compatible camera. This path is reversible and teaches you how your subjects, lenses and processing respond to infrared. Plan around static scenes and long exposures rather than expecting normal action-camera performance.

You need several creative looks
Choose full spectrum and carry the filters required for the project. The setup can cover 590, 665, 720 and 850nm looks, but filter changes add time, storage needs and opportunities for dust or handling errors. It is the broadest creative system, not the simplest one.
You want a dedicated monochrome workflow
A fixed 720nm or 850nm conversion is easier to operate consistently. You avoid changing external filters in the field and can build a repeatable exposure, white-balance and post-processing routine around one spectral band.
How to try infrared with an external filter
- Confirm compatibility. Check the lens thread size and make sure the camera and lens combination can be used with the filter without vignetting or mechanical interference.
- Choose the band. A 720nm filter is the conventional starting point. Nikon identifies the Hoya R72 as a popular option.
- Compose and focus first if necessary. On a stock body, the dark filter may block the optical viewfinder. Use live view, or focus and compose before fitting the filter, then avoid moving the camera or changing focus.
- Mount the filter securely. Make sure it is fully seated and that no visible light leaks around the filter or adapter.
- Stabilize the camera. Use a tripod for exposures that may run into the 30–90 second range in bright sun. Stabilization protects the camera from your movement; it cannot stop an animal from moving.
- Set a custom white balance. Infrared does not render colors like visible light. A custom balance gives the file a usable starting point and helps you judge the scene consistently.
- Review motion and focus. Zoom into the animal’s eyes, fur and edges. If the subject moved during the exposure, shorten the exposure only if the camera and light allow it; otherwise this setup is the wrong tool for that behavior.
How to plan a camera conversion
- Choose the donor body. Select a camera whose ergonomics, lens availability and live-view or electronic-viewfinder system suit your wildlife work. The conversion is permanent to that body.
- Decide between fixed infrared and full spectrum. Pick a fixed 720nm or 850nm conversion for consistency, or full spectrum if you need several wavelength options.
- Read model-specific calibration notes. Confirm how the converter handles infrared autofocus and which lenses or focus modes have documented support.
- Plan your white balance. Infrared requires a custom white balance. Record a repeatable procedure for the chosen band so that files from different outings remain comparable.
- Test live view and autofocus before a wildlife trip. Check focus at the distances and apertures you expect to use. Infrared focus shift can turn an apparently successful conversion into consistently soft images if calibration is not correct.
- Build the field kit around the conversion. A fixed conversion minimizes filter handling. A full-spectrum body requires the external filters for each wavelength you intend to shoot.
Autofocus, composition and exposure pitfalls
“Will autofocus work through an infrared filter?”
There is no universal yes. A stock camera’s autofocus system is designed around visible-light behavior, while infrared focus can shift. A converter may calibrate autofocus as part of the conversion, but performance is model-specific. Verify the converter’s documentation rather than assuming that a camera body, lens and autofocus mode will behave like a visible-light setup.
With an external filter on an unconverted body, the safest procedure is often to focus and compose before installing the dark filter, or to use live view if the camera can display enough of the scene. After fitting the filter, do not change the focus distance unless you can confirm focus again.
Why the viewfinder may go black
A 720nm filter blocks most visible light, so an optical viewfinder can become too dark for practical composition. This is a limitation of the viewing path, not necessarily a fault in the filter. Live view and electronic viewfinders are more useful because they can display the sensor’s infrared image.

Why the file may look red or otherwise unusual
Infrared files do not contain ordinary visible-light color information. They can display false colors because the camera’s channels respond differently to the remaining wavelengths, but those colors are not a normal record of what the eye saw. SWGDE recommends converting infrared images to black and white when that best serves a documentation purpose. Artistic wildlife work can retain the false color or use channel-swapping techniques for a stylized result.
Why a technically sharp frame can still look wrong
Infrared contrast differs from visible-light contrast. Foliage, sky and fur may separate in unexpected ways, and an uncorrected focus shift can make edges look soft even when the exposure is steady. Evaluate focus and tonal structure separately: first determine whether the subject is sharply focused, then decide whether the infrared rendering suits the scene.
Common failure modes and fixes
- Everything is blurred: On a stock body, the exposure may simply be too long for the animal. Use a converted body for moving wildlife; a tripod only addresses camera shake.
- The frame is nearly black: A 720nm filter on an unconverted body may require much more exposure than expected. Confirm that the filter is the intended wavelength and allow for the camera’s internal IR-cut filter.
- The animal is soft but the background looks acceptable: Suspect infrared focus shift. Recheck the converter’s autofocus calibration notes and test the exact lens and focus mode.
- The viewfinder is unusable: Compose through live view or an electronic viewfinder, or focus before fitting the filter on a stock body.
- The colors look inconsistent: Set a custom white balance for the infrared setup and keep the same procedure for comparable files.
- The workflow changes from shot to shot: A fixed conversion may be preferable to full spectrum if changing filters and wavelength decisions are slowing down field work.
What the choice means for cost and commitment
An external filter has the lowest initial commitment when you already own a compatible camera, because it is removable and the body remains a normal visible-light camera. Its hidden cost is usability: very long exposures can make the setup unsuitable for the wildlife behavior you actually want to photograph.
A dedicated conversion adds the conversion service and permanently changes the donor body, but it provides the most direct route to responsive infrared shooting. A full-spectrum conversion adds the widest creative range and the greatest accessory burden because you need filters to select each band. Product prices, availability, turnaround times and warranty terms vary by converter and should be checked at the time of purchase.
Quick Recap
A decision checklist
- Choose a stock body plus removable 720nm filter if you are experimenting, photographing static subjects or want a reversible first step.
- Choose a dedicated 720nm conversion if you want a classic infrared look with a consistent field workflow.
- Choose a dedicated 850nm conversion if strong monochrome rendering is the main goal.
- Choose a full-spectrum conversion if you need to switch among 590, 665, 720, 850nm and other filters.
- For moving wildlife, prioritize a converted body, live view or an electronic viewfinder, and documented infrared autofocus calibration.
Bottom-line recommendation by use case
| Your priority | Most suitable setup | Why |
|---|---|---|
| Experiment with the least commitment | Removable 720nm filter on a stock body | Reversible and inexpensive to try, but limited to static or nearly static subjects by long exposures. |
| Photograph moving wildlife | Infrared-converted mirrorless body | Removes the internal blocker and supports a faster, more practical field workflow. |
| Use several infrared styles | Full-spectrum conversion with external filters | Lets you select different wavelengths, including 590, 665, 720 and 850nm. |
