I took a body cap from my 7D and cut a hole in it. Then took the mount ring off of a Pentax K1000 Body, drilled a few holes in the EOS body cap and screwed the Pentax ring on to the body cap then mounted it to my 7D haha here are some pics.

Neat DIY, do you still have infinity focus?

No it is only good for close ups, the rear element of the Pentax lens is to far away from the sensor to have infinity. I know I could grab an adapter for a few bucks off of feebay but I figured I would try something myself and all of the items were readily available.

But you killed a K1000 body you could have sold for probably 2x the cost of an adapter! :lol:

Did you have to remove the aperture lever on the Pentax lens? There's some suggestions that it interferes with the mirror. Can't see how myself.

On the crop sensor camera you do not have to. On a FF sensor you do, the lever will hit the mirror. I have a 7D so no worries. Plus I used the body cap to do this so my lens sits farther away than the manufactured adapter.

I'm pretty sure mirror clearance with pentax lenses is only an issue on full frames.
