Questions about this item:

Shopper  What is the difference between the Hoya R-72 and the Hoya RM-72?
PHILIP H  The R72 passes infrared rays 720nm and above. The Hoya RM90 passes infrared rays 900nm and above. If you've seen R72 and RM72, then you're likely looking at the same filter. The numbers in the names represent the cut-off in the color spectrum (i.e. R72 = blocks all light wavelength below 720nm and RM90 = 900nm)
James W  Will this filter work with Digital cameras like the Nikon D700 & D4?
WILLIAM W  I don't know about the specific camera. The general rule is it works better on older cameras. Also, it takes like 30 seconds to get the exposure correct. The newer and more restrictive the camera is the longer it will take to get the shot. You can type your camera and the filter into Flickr to get examples of other peoples shots with the lens/camera combo. The shots come out all red and it still takes alot of photoshop but it is fun filter. Sorry this wasn't exactly the answer you wanted -b
