I taught beginning and advanced photography for several years and often had students who could afford, and bought, the latest in equipment, but were and would always be lousy photographers. It wasn't their fault in many cases because they never studied composition or lighting or any of the other things that characterize good photographers -- but they sure had the best equipment. I am always amazed by the members of this group who gladly specify the kind of equipment they own but never talk about their work. To me, it's like a woodworker bragging about the shop equipment he owns, but an inspection of his work shows that he doesn't produce better quality products than someone with much cheaper tools.

When I was a teenager I worked in an auto repair shop where the owner paid more attention to the quality of work the workers produced than he did to their toolboxes. Sometimes, he said, a better toolbox just meant they had better credit or more money in their pockets that the other mechanics.

Just observing.

Quoting from LensVid:

"Cameras are for older people – you can’t see this in the numbers but we clearly see this all around us – aside from the professional segment – dedicated cameras do not interest the younger generation. The people who are still interested in photography are typically around the ages of 40-60 or more – the same people who maybe shot with analog cameras as youngsters and now have the time and money to invest in photography as a hobby – their children and grandchildren are far less interested in cameras and prefer to use their smartphones."

In other words, as we die off, so will the camera business.

Good God. You young people are a little sensitive aren't you? Canon and Nikon have both reported a drop in camera sales. Why? Cellphones. Are they cameras, yes. Would I own one, no. I do not need instant gratification. I am not so important that I can't miss a phone call. I absolutely hate to text. I have a 27" 4k monitor, if I want to find something on the computer. and if I am going to take a picture, I will use my Canon camera. And depending on the situation, with the lens I feel with be the best choice. And there lies the difference, my choice. I had a cellphone and threw it away.
Now to what the Gentleman wrote, if you look to see who posts pictures and who replies to posted pictures,the majority are people are around my age. In their 50's and 60's. We do have more disposable income. We have more time to pursue photography. We are not a cell phone culture. We tend to look up instead of down, at a little tiny screen.
As to who makes the sensors, who cares. I am sure it is a camera company, that is basic economics. Supply and demand. They would be foolish not to produce one.
I am so sorry your little feelers get hurt when, old guys like me, with cameras. Laugh at your cell phone. Make a duck face, take a selfie and chill out.
