Someone Invent this P645/67 adapter for me.

Extension helicoid! The 105 doens't focus close enough on it's own, it would be nice if an adapter had an exension option to get in a little closer.

Since it's my idea please give me a free one.

As Lauren indicated the Helicoid extension tube is an option, as well as the Auto extension tube set.

You can also get a Pentax S82 (67mm) close-up attachment for the 6x7/67 105/2.4 lens.

This will give you magnification of 1/7.8 ~ 1/3.7x.
