Well, as the lens and camera are a closed unit without any options, they behave as if there is no system (of interchangeable lenses). No system, no lock. If you have more than one lens and them interchangeable, there's a system, and if the mount is exotic enough, you're locked into it.

Funny this, to be very honest.

I used to shoot a Canon G10 as my carry around camera. However, I really wanted more from a camera that size, so eventually got a Pen-F, MFT, and now can use the 22 exchangeable lenses I have for the MFT-mount, plus my Canon lenses if I feel the need with one of three speedboosters and adapters, while still having a portable click&shoot camera when i need it at approximately the same size as the Canon, with way, way, way better IQ, and many more possibilities.

Being locked in is very relative. Personally, I would feel locked in with a camera like the ZX-1. For all intents and purposes it is a camera system that locks one in in a very extreme way, if you'd ask me. For each different option you'd like to use you need another one of those locked-in systems. And then to pay an amount for it which is probably going to be around the 4000 euros or thereabouts, even I would rather carry a FF DSLR ....

In short, IMO locked-in is relative, but the worst case would be a single type of use camera, with no interchangeable stuff at all.

Kind regards, Wim
