Andrew: Thanks for the pic. Did you make the adapter yourself?
Dunk: yeah....
However, at this point, I think I'll go for the 40mm. While it's more expensive than the 50mm, I can afford it now without breaking the bank. If I "need" to get a 50mm later, the lower cost will be easier to justify. How's that for some warped logic?
Now to find the best source for buying the 40mm....
