Ok, boomer.
What I meant was if Canon or Nikon wants to attract new camera owners like those born 1990-onwards then they need to be able to be able to effortlesly share photos from large image sensor cameras straight to iPhone or Android without needing to install additional apps.
And they should have done this as late as in year 2012.
The sharp market size decline of the dedicated still camera market is attributed primarily to the rise of iPhones and Android smartphones.
Now with COVID-19 very few people are having events to be covered by any sort of working photographer.
The 5D4 came out in 2016 thus that feature should have been baked in on the first shipments back then and not 4 years later.
Should voice-calls, text, and games be added too? You might be onto something. Maybe Adobe, seriously, already has a version of LR ready to use on Sony cameras? That would be really amazing!
As for saving the big-camera (meaning cameras that take two hands to hold) industry, I'm not sure that just better sharing would be able to solve the problems of portability and Swiss Army knife usefulness that phones offer. Can you imagine all the girls out clubbing, taking selfies with their besties using a 5DIV? I can't. My R6 doesn't fit in a purse or pocket. It isn't with me 24/7. It doesn't let me do Instagram (but maybe it should)...Banking? Nope. But, hey, maybe if we could just share some jpegs taken with a $3000+ body with a large lens, that would crack the generational code!
On the other hand, a few extra sales might have been generated with an Instagram button. Maybe. 20-20 hindsight.
And, btw, I've found that those who start an argument pointing out age are just reaching that age when they are starting to worry about age. Paunch. A few gray hairs. A few less hairs. Not quite the energy you had just a few years ago. It's ok. Just get good rest, eat properly, exercise sensibly, and don't get lost in nostalgia.
Thanks for your compelling insights.
