Nikon D90 DSLR Camera Body {12.3MP} Infrared (IR) Converted Sensor

Nikon D90, Converted for Infrared-Only Capture

This D90 has been permanently converted for infrared photography, so its 12.3MP APS-C CMOS sensor now reads only the infrared spectrum instead of visible light. That means no removable filter to fuss with and no exposure penalty for shooting through a screw-on IR filter on the front of every lens. You get the D90's established body: a 11-point autofocus system, a 3-inch 920,000-dot LCD, and a pentaprism optical viewfinder with 96% coverage, all put to work on a genre that rewards deliberate, considered shooting.

Exposure control stays fully manual, aperture priority, shutter priority, or full manual, with shutter speeds from 30 seconds to 1/4000 sec, so you can work IR landscapes in bright midday sun, when foliage glows brightest, or stretch long exposures for surreal cloud and water effects. ISO runs 200-3200 native with a 6400 boost option, giving you room to work in the lower-light conditions IR conversions often demand. Continuous shooting at 4.5 fps and a 850-shot battery life mean you can stay out shooting a full session without swapping cards or batteries constantly.

Since the conversion is permanent, this body is committed to infrared work than switching back and forth. That's a feature, not a compromise, for anyone who's tired of juggling filters and long exposures to fake the effect.

Who It's For

Landscape photographers get the most obvious benefit here: infrared conversion turns green foliage luminous and skies dramatic without a screw-on filter costing stops of light, and the D90's 30 sec to 1/4000 sec shutter range covers everything from bright noon IR work to long, moody exposures. Fine art and experimental shooters gain a dedicated tool for surreal, otherworldly tonality that would otherwise require constant filter-swapping on a standard body. Architecture photographers can use the same glowing-foliage, deep-sky rendering to make building exteriors and surrounding landscaping stand apart from ordinary color work. Anyone shooting with existing Nikon F-mount glass can move straight onto this body without buying new lenses, since the mount and 1.5x crop factor carry over unchanged.

FAQ

What exactly does "infrared converted" mean for this D90?

The sensor has been permanently modified to read only infrared light instead of visible light. There's no removable filter-the conversion is built in. You shoot IR directly without screwing an IR filter onto the front of every lens or dealing with the exposure penalty that comes with external filters.

Can I switch this D90 back to shooting visible light?

No. The conversion is permanent. This body is committed to infrared work. That's the trade-off: you lose flexibility but gain the convenience of dedicated IR capture without filter juggling.

What shutter speeds and exposure modes does the D90 offer for IR work?

You get full manual, aperture priority, and shutter priority modes. Shutter speeds run from 30 seconds to 1/4000 sec, so you can shoot bright midday IR landscapes when foliage glows brightest, or stretch long exposures for surreal cloud and water effects in lower light.

What's the ISO range, and will I need high ISO for infrared?

ISO runs 200–3,200 native, with a 6,400 boost option. IR conversions often demand lower-light shooting, so this range gives you room to work without pushing noise too hard.

How fast is the burst rate, and how long can I shoot on battery?

The D90 shoots 4.5 fps continuous, and battery life is rated at 850 shots per charge. You can stay out for a full session without constantly swapping cards or batteries.

What autofocus system does this have?

An 11-point AF system. On an infrared-converted body, AF performance depends entirely on how the infrared-transparent lens elements interact with the modified sensor, so manual focus is often more reliable for IR work.

Does the 3-inch 920,000-dot LCD and 96% pentaprism viewfinder work normally with the IR conversion?

Yes. The LCD, viewfinder, and all optical paths remain unchanged. The conversion only affects what the sensor reads, not how you frame or review shots.
