I have had cameras with the traditional focus (Shen Hao, Gundlach Korona) and just find the worm drive a little easier for me. Especially when the lenses start getting long--don't have to reach way out in front. The worm drive on my Chamonix is very "tight" and solid. I don't feel any play at all. There is enough resistance in the mechanism that stretching the bellows doesn't seem to be enough to pull the front standard back. It's a pretty gradual advance so it's easy to fine focus too.
