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.

This conversion service replaces the cameras internal hot mirror filter with our high quality custom manufactured glass replacement infrared or clear filter. The DSLR autofocus systems are calibrated to the Nikon 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.
The X cameras are calibrated to focus universally.
