I'm curious, what is the reason that you want the 63mm lens?
The D6/D5XL is a bit "challenged" by 50mm lenses - the bellows needs to be completely compressed in order to focus when you are doing a moderately large enlargement of a 35mm negative.

Normally, I use the Omega masking accessory with my D6, but when I am enlarging from a 35mm negative, I have to remove it in order to permit the 50mm lens to be closer to the negative

So a slightly longer focal length would be good.
