The HSK Full-Spectrum Conversion
The HSK is our full-spectrum conversion service re-engineered to eliminate hot-spots with problem lenses when shooting in the infrared spectrum. (Click here to read the full story behind how it works!) We install a dual-AR coated, full-spectrum ND glass filter to give your sensor the spectrum correcting properties needed to shoot IR hotspot free with more of your lenses. Please note: This conversion will completely eliminate most hotspots, but will reduce overall exposure by approximately 4 stops of light. This is ideal for fine art, landscapes, portraits, studio and other demanding photographic work where image quality is paramount. Though it is redesigned for hotspot elimination, the HSK full-spectrum service will still provide all of the capabilities of a normal full-spectrum conversion, making your camera compatible with all IR filters at handheld shutter speeds.

NOTE: Dust reduction systems are disabled after conversion.
* The D40, D3100, D3200, D5000, D5100, D5200, and D7100 will not be able to set a white balance after conversion in most cases. Some other models can also have trouble setting a white balance and may need to be set in RAW.
** V1, J1, Z6, and Z7 will set a white balance on the 720 and 850nm filters only. They are calibrated to focus with all lenses.
† The D700, D750, D3, D3S, D3X, D4, and Z7 contain an IR internal shutter monitor that may contaminate the shot when shooting long exposures. This will generally only affect UV shooting. The D7000, D7100, D600 and D800 also have this monitor but do not have this contamination issue.
This conversion service replaces the camera’s internal hot mirror filter with our high quality custom manufactured glass replacement infrared or clear filter. The autofocus systems are calibrated to the 50mm 1.8mm lens. This calibration results in general focus accuracy for most lenses from 18-300mm. You can also send your own lens to be calibrated to instead at no additional charge. Note, ultra wide angle lenses need special calibration. If calibrating to an ultra wide angle lens the autofocus will not work with telephoto lenses.
