    Rack & Pinion == What?

    Are rack & pinion focus lenses common as taking lenses,
    or are they as I suspect projection lenses?

    Most common on projection lenses but way back when taking lenses had rack and pinion focus too.

    Probably both, because if you ever used a large old portrait camera, the fine focus is not so smooth/precise (as you are pulling/pushing the standards/bellows with the wobble/resistance inherent), so much easier just to final focus the lens...

    Yes, I have and have used an 8x10 studio camera but have not found it necessary to futz with fine focus provided by a rack focusing device. My loss perhaps.

    Thanks to Dan and Steve for clarifying the issue.
