16mm c-mount lens, zeiss prime 35mm/4k....adapters?

[tylerindo1]

So I've heard c-mount lenses need no adapters but that if they are not modifed it can cause issues with the focus: example of cheap modified lens http://cgi.ebay.com/MODIFIED-C-moun...54051684?pt=Camera_Lenses&hash=item27bbc62d64

Is c-mount a standard size or do 16mm lenses require an adapter to put on a GH2?

I also have access to a ziess prime kit, 35mm/4k...is a PL mount what i need in order to use these with my GH2?

That's one of my babies right there. Most if not all *zoom* lenses require some sort of modification, yes. And you also need adapters: C-mount to Micro Four Thirds. C-mount is technically 'M25', i.e. the diameter is 25mm. 16mm lens come in a variety of mounts, most being arri mount I presume. Don't know about your zeiss kit, it should say what mount it is? Either way it wouldn't be Micro Four Thirds mount...

not sure about the zeiss lenses, they rent them with the redcam, so prob 4/3 to pl?

And the 16mm are c-mount
