clip-in adaper for a 36mm UV-IR cut filter to use with my D5300 after having modded the camera. Should work for other Nikon APS-C cameras too. Warning: check first without filter, see if the shutter has full freedom of movement with the clip-in installed. It should be OK. While blocking the shutter doesn't immediately break it, it might cause damage and it will cause nasty horizontal vignetting in your pictures. Works with Nikkor lenses, and does not vignet my f/2.8 lens. Faster lenses, like a 135mm f/2, might vignet. See the attached flat from an f/2.8 lens for reference. Why not insert a rectangular UV/IR-cut glass when modding? To not have to cut glass and have a good UV/IR-cut. To be able to use the DSLR full spectrum modded. I'd like to at least be able to experiment with IR shots for for example the moon. Additionally, now I can use a narrowband filter without having a redundant UV/IR-cut filter in the imaging train.
