If Panasonic abandon M43 mount, what make them think that the existing m43 users will switch to their FF mount or the wild guessed APSC (L mount)? One has to rebuild the system from scratch.
There are so many such (FF/APSC) mounts and choices already. I personally will just go back to the Fuji X if i do not need FF. Fuji now has the IBIS in their new mid-range body. The attraction of m43 system to me is their choices of pro and high quality lenses from lumix and OM company (JIP).
I think that’s a good question.
If Panasonic doesn’t provide an easy pathway to upgrade from m43, what incentives would Panasonic m43 users, or m43 users in general have to move to L-mount? In fact there could be some backlash to the abandonment
Unfortunately I think they boxed themselves in with L-mount cos whilst an m43->L adapter may be technically possible, it’s a very difficult adapter to make.
With 3 other competing FF/APS-C mounts occupying a mammoth triopoly, starting from scratch L-mount is up against:
1) most established (Sony)
2) most potential (Z mount)
3) largest (Canon overall is larger than Nikon and Sony combined and they’re just getting started in RF)
If we add in the very strong APS-C only X-mount then the competition for m43 users (if m43 is abandoned), is even stiffer.
The only thing I can really think of is FF video but then Panasonic betting on DFD is a risky gamble when OSPDAF is already proven.
I still think L-mount is a mistake by Panasonic. If they wanted to do FF, they should’ve made a mount with the same electronic protocols as m43 but in a large enough mount to make pass-through adapters feasible. Then it’s a no-brainer to migrate your m43 users to the new mount as their lenses would work perfectly and you’d have a new system catering to both FF and m43 sized sensors, which is a better separation than FF/APS-C IMO.
