Well, I worked with still film and digital cameras and scanners, not video. I have come to a different conclusion. Sure there are differing levels of talent, but that stratifies with the importance of the product. You cannot keep all the projects with the aging elite. You need to develop the talent.
No, you did not slam everyone. But I do find you like to pick your winners and losers. You slam the Japanese for not innovating and then give a passing mark that Phase should be coming out with a new camera soon. They have been coming out with a new camera for a long time. Locking dials on the Df are really horrible? It seems you are just looking to complain--we certainly get you don't like the Df. Ironically, your latest post calls for simplification in cameras. BTW, things like GPS cost money to put in a camera and since the point of the Df was to simplify and they also needed to control costs, it actually makes sense they dropped the GPS from the body.
You also seem to be a bit confused about how the market developed. Lets take your Sony example. Manufacturers use existing film system mounts for two really good reasons. First, it allowed them to make DSLRs without having to go to tremendous expense of making new lens lines and some of the lines were very extensive. It also lets customers use their existing lenses and nothing angers customers like when they think the company is not supporting them. It was a win for both sides. Sony bought Minolta as a step into DSLRs as well to grab some existing customers. APS became the dominate format for amateurs because of cost. It was also cheaper for the manufacturers to start developing APS lines while having 35mm lenses available. No one, manufacturers nor customers, were going to wait for affordable 35mm sensors. It is also cheaper to make APS lenses and so, when they had APS products, they made lenses to fit--if you thought you might buy a 35mm camera, you should not have bought APS lenses. (APS also needed wides which would have been really hard to make with a 35mm image circle.) Sony had the foresight or luck to make the NEX mount large enough to handle a 35mm chip, but knew it needed to be an APS camera as they were unsure if that would be a consumer camera or an enthusiast camera. They certainly adapted and changed as the market shifted, even driving new markets. Sony has now decided to make another risky move to a FF NEX or a7 series camera. Cameras are expensive to produce as well as lens lines--they do have an a-mount adapter for their DSLR customers. So you are going to have to wait for the lenses. But if this venture fails, then Sony needs to pull out. Lets hope consumers like the cameras and buy them. That is how it works. But the mount development is far from random.
Hasselblad is an outlier, at least their space-shot series. That project was clearly from someone outside the industry that felt they knew how to make cameras better. All that example says is you need more than an MBA to work in the camera industry. I also think you will find this venture will fail miserably. And Hassleblad has not been the first to make this mistake. But this is hardly indicative of the market or industry.
I am sorry, but I simply do not see your premise that "many camera dogs" are produced. Nor that the industry has their heads stuck in the sand. The shrinking industry may well be beyond their control simply because people don't want cameras--you can't make people buy what they don't want.
