I have a D5500 and use it all the time. The Dichroic Head can be mounted to a "D" Series enlarge via an Omega Adapter. I am not sure of the carriers - I only use the sandwich type for 35mm, 6x6 and 6x7. Lensboards --- agian I don't know - I have the three lens turret.
I love this puppy... I find it *very* stable and repeatable ... no problem to go back to a negative six months from now and still have the color in balance.
