This database reports on the test of Nikon lenses on the Nikon D800 modified for full spectrum (UV-VIS- IR). For the specific needs of infrared photography for art documentation it is helpful to have detailed information on lenses behavior at different aperture. Depending on the application and the task the infrared photo should be taken, low or high aperture numbers could be necessary. Hotspots become more apparent at higher aperture numbers, while often disappear at the lowest numbers. Hotspots are caused mostly by the coatings inside the lens barrel and on the lens elements or by the interaction between the lens elements and the imaging sensor. Lenses show hotspots when shooting infrared photography.
