It;s just the PHD (push here, dummy) cameras that will disappear. In turn, the DSLR will get cheaper, and along with better cameras in phones, will fill in the gap the PHD cameras left. There’s already a phone with dual lenses to shoot 3D pictures. I wouldn’t be surprised to see, in a couple of years, phones with 1 or even 1.5cm lenses, and maybe even small telescoping lens stacks like the smaller PHD cameras.
No the cheaper cameras won’t disappear, they’ll just become freepies that are given out with magazine subscriptions. And phone cameras suck. I’ve yet to see one take a better picture than a regular cheap digital camera.
And they may come as a surprise to many here, but many of us don’t want all the crap they foist on us on our phones.
There used to be something about the right to privacy. It rings a bell, but I ain’t quite sure? A little help?
