We have to remember that there is no perfect camera in this world. There will always be limitations to what a camera of one generation, give or take differing technologies that is given priority for a production model. Market segmentation is also another area for a business to protect if they were to be viewed as a long term investment for shareholders. So we can’t have everything. If that happens, one day we’ll have just one camera that we will not upgrade for the next decade. And judging by how the digital imaging segment is shrinking due to smartphone imaging technology, most consumers won’t even think twice about switching phones rather than cameras. That leaves an even smaller market for digital imaging device manufacturers like Sony and Panasonic. It’s a death spiral. For example, if you want to make sure your native lenses stay relevant in the future, sometimes letting the camera bodies take the brunt of being disposable is not a bad thing. Because investment always require a sacrifice one way or another. And it just happens that lenses are the better investment. (Just my point of view over a shot of whisky?)
