[Clive Alex]

Does anyone know how to open a Carl Zeiss 50mm f1.5 sonnar it need a clean and although I've cleaned many a Still camera lens I'm not sure were to start with this one. It's vey similar to Arriflex's standard mount Xenon lenses.

Depends what you want to clean, how far in you need to go. Lens work is generally not easily undertaken. You need proper lens tools and it's very easy to lose collimation or damage elements. But if you have some experience, post some pics, maybe I can help.
