35mm lens to digital rebel adapter

[egproductions]

I can see that when I manually place my 35mm pentax k mount lenses to my digital rebel the back focus distance is doable (abviously with a 1.5x factor) Is there an adapter that is sold that will allow me to hook these lenses up or do I have to make one myslef?

also if I have a f/2 50mm 35mm lens and I place it on my digital rebel and it becomes more like a 75mm lens do i still get f/2 out of it or does it loose a few stops?

I atempted taking a dust cover for one of my lenses and a dust cover for the digital rebl and attaching them so that it would act as an adapter. Theortically it would work but I dont have equipment to cut that precisley and ended up breaking the dust cap.

I found Canon FD (not Pentax) to rebel:

Keep seraching or switch to other lenses. I (hardly) managed to get a Nikon 1.2/55 on Sigma SD10. No room for adapter (due to flange distances) but awesome pics.
Machined down the end of Nikor lens.
