I have no idea if any of them will fit. I know the part numbers are different but I also know that doesn't mean they won't. I'm interested in the 473-124 (2 of them) if they will fit. The current model is http://www.bhphotovideo.com/c/produc...Glass_for.html. I would also be interested in the 423-219 and 423-224 if they will fit. They definitely look different but again, I don't know if they will fit. http://www.bhphotovideo.com/c/produc...25_x_2_75.html is what the negative carriers look like. Let me do a bit of research to see what I can find out about cross-comaptibility. I'll email omega.
