I just orderd a 67mm Hoya R72 Infrared filter for doing IR with my D70 and got a notice that it's backordered. Just like every other accessory for the D70. It's not a D70 specific filter, just the size (67mm) which is the size of the kit lens filter thread. I was hoping to try some IR out this weekend Maybe do a little x-ray photographry of the babes at my apartment complex I got really excited when I saw these IR pics taken with the R72 and the D70 http://www.pbase.com/nzphoto/infrared_d70&page=2 and these http://www.pbase.com/nzphoto/open_air_museum_in_ir_top In other news, I ordered another little toy on ebay. A slave trigger for flash. I've got some creative ideas for using it in addition to the built in speedlight on my d70.
