Hi All,
First time poster, long time lurker. I have a technical question about camera mounts. When Nikon and Canon introduce their own full frame mirrorless cameras (to compete with the A7) how likely is it that they will have to use a different mount system (in the same way Sony had to switch from the old A mount system for the A7)? Put another way, will Nikon and Canon users face the same problems we face with Minolta/A mount lenses? Will they have to buy adapters, etc. or is it technically possible to make a new mount that would accommodate old, DSLR-style lenses on a mirrorless body? I asked this because I often go through the pendulum swing of deciding whether to sell my A850 and minolta/Zeiss lenses and switch to Nikon (since I don't want to settle for an inadequate adapter to use my current lenses on an A7). However, since I think it's likely that mirrorless will eventually become the standard FF system in the future (and because there are things I like about EVFs, etc.) it would be galling to sell all my equipment, buy a D800 and lenses and then, in five or six years, have to buy an adapter to use them on a new Nikon mirrorless camera!
Thanks for any collective wisdom...
