I think its not totally about "Half done right".
When an OEM has professional models above the consumer level, they need to protect those pro models.
Pro model is where the $$ killing is made...I mean the buyers get stabbed here....ha ha ha.
Sony is loosing money as an electronic company, but their insurance business is making good money.
Black Magic is a good example of a company which it probably has nothing to protect, it only has so few cameras and they try to make
the best for these models......at a reasonable cost. But R&D need money. Small company like BlackMagic can not order sensors by the 500K quantity, so they will progress slowly but I hope they will do well.
Its quite the same like Nvidia graphic cards, the crippled some functions of their new high end gaming cards in order to protect the crazy expensive Quadro line which is used mainly by professional graphic station.
Recently FLIR did the same thing :
They sell low cost US$1K unit by locking its capability, while the engine-internal is the same as a unit costing US$6K ....ha ha ha.
Just firmware lock....holy cow.
Its all about busines, how to rip off more $$.
If your girlfriend or wive on day request you to get her a Hermes as below :
You will know that no leather will cost that much.....he he he....its the perceived image you paid for.
