The iPhone series are the most popular ‘camera’ in use around the world.
No one can deny that nor should they and without doubt they’ve changed the camera industry for ever.
But there will always be a place for large sensors, and fast lenses.
I’m an amateur photographer not a professional but even I have 2 bodies, a dozen lenses, a couple of tripods, a couple of flashes, several bags and sundry accessories totaling over $10,000. A recent poll on a photo website put me in the lower half of $ spent.
People willing to outlay that sort of money on serious cameras aren’t going to give up their DSLRs or Mirrorless cameras for a phone.
