Nikon lens on Canon body: Setting the aperture
This is a small pin you can make for adjusting the aperture when using Nikon lenses on a Canon body.
A friend of mine inspired me to make this, and I've dubbed it the "J-Pin". With the pin you can set an aperture of f/8, f/5.6 and f/2.8 (I haven't made actual measurements on the aperture values, but they are approximate).
I made it from a small piece of 2mm thick aluminium that I had, but a piece of hard plastic could also be used. I chose aluminium for durability's sake.

Note: The top of the pin has been tapered on one side
so that it will not touch or get stuck on the adapter-ring.
(see image 5)
.

You can make a groove (as seen above) on the top of the pin to make it easier to grab with your thumbnail when pulling the pin out.

The one I got has worked perfectly no problems at all.
