Yes. By extrapolating the very extreme of the original range (3-4k, 15-20 years) you managed to "win" on a technicality, on the internet. Congratulations. Of course, you then conceded the entire original point - that high end camera pricing has remained static for years, and therefore that the smartphone argument (the initial point) wasn't a value detractor from their sales. But who cares, because you got to construct an angle out of a conversation you weren't a part of to win a point on the internet. You go, girl!
Seem like your basing your whole argument about a comment said in a friendly forum discussion on absolutly no known facts and its basically your oprnnion. Nobody is here to win anythig and its all supposted to be a bit of fun. If you feel so defensive over aver little comment apposing your view, then why bother at all?
I'm looking at EOS-3, EOS-5, EOS 5D, EOS5DII just from Canon and none of these were £4K cameras.
Looking at you sales figures you kindly posted, interchangeable camera global sales seemed to have increased year on year up to 2012 when there was a sharp decline. Coincidently, the 5DIII in 2012 was the first Canon camera to jump up in price from the normal inflationary trend and was also around the time smart phones started to get serious over photography.
Reporters no longer needed photographers, news rooms could obtain cheap images all around the globe, image lead social media exploded and everyone had easy access to a camera.
Its just my opinion, you are welcome to form you own so please don't be offended by it and throw any more cheap insults "
You go, girl!" at people please.
