For discussion purpose only. Nothing to do at year end.

How much is the chance of Zeiss to produce Z m4/3 lens? Is m4/3 trademark registered by OM, Panasonic etc. or is a generic mount?

Am I correct to say that Hologon and Biogon design could be applied on Z m4/3 lens? If yes I would see selling point here.

FOA , despite what Oly would say .. the 4/3 and M4/3 is not open and it would require joining their 4/3 consortium to be able to participate. Its also highly non generic. Witness the problem of using Panasonic lens on Olympus and vice versa ( they used different take on distortion and CA correction )

It made little sense thus for a brand like Zeiss to produce lens for M4/3 ( in a way M4/3 lens can only be for M4/3 and thus not business vise any good )

The Hologon is perhaps the worst thing you should put onto any digital camera due to its rather design which would put highly oblique ray onto the sensor and this the gating effect would be maximized and thus imaging quality highly degraded ..

One can of course use the lens on any of those digital body but just do not expect them to be of any special .. after all they are not mean for that application.

History had tell, with advance of imaging means also mean requiring update of optical need , which is very much the case now

Very true especially on the point that there is inherent limitation of applying Hologon design on digital sensor. Thanks.
