It is interesting to consider camera product compatibility and differentiation, as sometimes these factors can work at cross purposes. There are photographers who feel that OMDS should make its proprietary computational photography technologies compatible with lenses from other manufacturers. And, that OMDS should expand the compatibility of these technologies further down its own product line to include less expensive lenses.
Some other photographers are upset that Canon appears to be ready to bar third party lens manufacturers from using its new camera mount and suing them if they attempt to reverse engineer the design. Some folks wonder if this could eventually lead to third party lens manufacturers disappearing down the road.
