Hi, the cool thing about century is they have the focus ring that can be set to have a limit of movement. This is not avaiable in the Chrosziel. However, as far as I know, the Century rig has no focus dial on the side like the Chrosziel, which is the basis for ergonomic focusing. I have set up several kits for customers incorporating the Chrosziel support and dial with the Century focus ring, to get the best of both worlds (Very expensive, though, like you didn't already figure... )
