Canon LTM Canon 35mm f/2.8

Canon M39 M39 screw mount bodies/lenses
I just got the lens in, it's very nice. Are they all screw mount? Also I have a question about the focusing, is the focusing image on the bottom of what you're focusing on as opposed to directly on top?
 
The focusing system on the Leica, on the M3 the image layed directly on top of one another. On the M2 I just got the image lays under one another when it focuses.
