Canon Pentax Lens

Canon Pentax Lens
Is the Pentax SMCP-FA 50mm f/1.4 Lens compatible with Canon DSLRs like the 40D?

I am thinking of buying this lens for my film SLR (A pentax SF-10) but I am looking to moving into a Canon dSLR in a couple years, so I would like to purchase glass that is compatible with what I have now, and what I would buy in the future (the Canon 5D is well beyond my pricepoint – looking at mid to entry level dSLR)

The mounts are different between Pentax and Canon gear. It won’t work.
