Konica Autoreflex T2 macro / pinhole system for sale on Ebay

I've decided to sell off one of my Konica Autoreflex cameras in order to finance some other projects. Besides, I have a T3n set just like it, and I'm having a blast with the homemade cameras right now.

So, it's on Ebay. Click on the "Buy a pinhole on Ebay" link on the sidebar and it will be in the list.

Here are some detailed pictures (I'm too cheap to post these on Ebay, and they are much larger here and thus easier to see. Click on a picture to see a larger version).

Here's the complete set: Konica Autoreflex T2, 57mm f1.4 Hexanon lens, Prinz automatic extension tube set (36mm, 18mm, 13.5mm), two pinhole body caps (a 0.25mm and a 0.35mm), and a table of focal lengths and f-numbers for every possible combination.

These cameras are built like tanks, and they have excellent optics. The camera body has some wear on the paint and some small lifting of the leatherette, but it is fully functional (with the exception of the meter - I don't know if it still works. It did last time I had 1.35V batteries).

Here's how the multi-focal length pinhole thing works: you can extend a pinhole cap away from the film with an extension tube. See the table below for all the possibilities!

Here's a closeup of the extension tubes.

Here's a table with all the possible combinations of focal length (approx) and the corresponding f-number for either pinhole. The bold numbers indicate that you will get a sharper image at that focal length with that pinhole size.
