I just wrote the text below in another forum thread - much weaker sales than in the years before can't all be blamed to a Brexit or the rise of camera phones alone. This is also one of the reasons:
People say that camera sales are massively falling because of smartphone use - but nobody talks about one major difference between smartphones and DSLRs:
- With a current iPhone 7 or Samsung S7, hardly any realistic wish for features and functions is left open. It's very hard to imagine which real essential things the manufacturers should come up with in the future. If you own one of the top smartphones of one of the leading manufacturers, there are no real reasons to complain about the few specs that are better in the competitor's product. You can survive with the functions of the current smartphones for decades, and it feels like as if everything's there.
- With a Canon DSLR that is 5-10x as expensive, you can easily make a realistic future wish list of a few dozen relevant missing points, because those functions are already implemented in lots of other existing products by the competition (many in mirrorless cameras). While the quality of the cameras is great in itself and you can use them for many years to come, a lot of things are limited, and logistics and workflow are not as convenient as they can be. A lot of extras and multiple devices need to be bought to be able to have allround capabilities.
Final result is: A 2016 smartphone just feels good and not like an expensive thing to buy for what it gives you. A 2016 Canon camera feels expensive, because you know the company has left out many things and didn't even pretend to try to release the best they can do. That is also the main difference to Sony. An A7RII or A99II feel much more as if it's the best Sony could come up with at the time.
