View Full Version : Lens mount

I have just ordered a DFK 31AU03.AS and was thinking about buying a lens for wide field astro photography with it. The spec says that the camera takes a c/ CS mount lens, however there is a different flange to focal plane distance between the C & CS mounts, so which type of lens do I need to ba able to focus at infinity?

the AS cameras do not come with a 5mm ring (because they have a nose piece). So you either need a 5mm distance ring to use C-Mount lenses or you use CS-Mount lenses without a 5mm distance ring.
