Originally posted by Winder From what I have read. L-mount is probably an option. Panasonic and Leica (obviously) were going to develop for the L-mount regardless of what other companies decided to do. Sigma was invited as was Olympus. Were other companies invited? I don't know. Ricoh seems like a prime candidate for the partnership. Panasonic doesn't appear to be interested in developing on-sensor PDAF and they are going for the large body. Sigma will use a Foveon sensor. There will be a market for a manufacturer who can make compact FF bodies using PDAF sensors and there will be a market for compact glass. Everything from Sigma and Panasonic is huge and expensive... Leica obviously so. Panasonic is struggling so I don't see them adding more L-mount bodies in the near future. I think the 3 that they currently have will be improved via firmware updates over the next 2-3 years before we see new bodies as Panasonic will focus on glass. A GH-5 & G9 replacement should come late next year.
I really wish Olympus had decided to join the L-mount. FF mirrorless is where the growth is and has been for the last few years.
Ricoh has to eventually do something. This is not an industry where you can rest on your laurels. Look at what has happened to Canon and Nikon in just a few short years. They are playing catch-up in the market. Obviously Canon and Nikon are huge companies and they still command a massive share of the industry, but they have fallen behind in several key areas.
Leica is the only one who could keep someone from joining the L-mount as the L-mount is theirs and they would have to grant a license, but other than a license from Leica I don't believe there is any restriction. There are anti-trust laws against cartels and the L-mount alliance would find themselves in trouble if they were working together to restrict competition.
So, Panasonic and Leica, old collaborators, decided to extend their collaboration with this L "alliance". Then, they needed someone to make lots of lenses for them (but not overly competent in cameras) - enter Sigma. Supposedly Olympus had a role, too.
Yet I don't see a good place for Ricoh Imaging. It's the same Ricoh Imaging who is barely releasing products, behind in AF and video; would they beat Panasonic in AF? Would they launch more cameras like Panasonic?
IMO they'd be outcompeted within the system. Can it work? At the very least, I believe it would be very, very difficult.
Are there anti-trust laws forcing a company to share their intellectual property with everyone?
