DSLRs are dead, and lenses are never going to be the same
The largest market of photography dilettentes (like me) switched to phone. Most people just want a shitload of bokeh (real or software), sharp wide angle without a lot of distortion and ability to zoom without losing too much detail.Besides, most Good Photographs are 90% technique/framing/instinct/editing NOT hardware. (Just get closer to your subject.) "The camera you have with you..", too.So, that only really leaves Pro wedding, sports, and, journalists and that just isn't nearly as big a market as the golden age of late 00s DSLR Flickr hobbyism
