Is this still an option or will an adaptor be available ?

And if so should you buy the C or PL mount version and are they themselves able to be swapped ie: if you buy the C mount can you simply buy the PL adaptor to use etc

The standard camera has C-mount. You can order the PL-Mount which is added to the front of the camera. There are various inexpensive C-to-F mount adapaters on the market. However, we do plan on offering a hefty F-mount option in a similar configuration as the PL-Mount.
