Comments about Hoya 52mm RM90 Infrared Glass Filter:
A gateway to deep IR region. Equivalent to 87A with a transmission curve starting at 880nm and %50 opacity at 1050nm.
Focus corrected lenses may be required. Works well with wide spectrum converted Nikon D700, focusing may be done with Live View since nothing could be seen from the viewfinder.
