jeffa4444 said:Nothing about it is new and how they can claim a patent in beyond me. You can change mounts on Arri Alexa cameras for instance from PL to Panavision retaining electrical contacts, you can change a C700 from EF to PL in fact you can go back to the sixties and see cameras where mounts were changed altering the back focus.
Panasonic / Olympus made adaptors to move from 4/3rd to m4/3rds with electrical contacts.
Nothing of significance is shown in this patent.
As far as I can tell, it is a patent application, not an approved patent. And we do not know from that if the patent is for the idea or how it is implemented.
So yes, there may be some significance.
And increasingly the US Patent office is getting lazy. With borderline cases they sometimes take the view of 'it looks OK, but I don't understand it. I will approve it and let the court make the decision if someone challenges it". I know from experience that most patent applications are really there to stall the opposition not to actually get the patent.
