Smartphones make great pictures for normal people and its great but they don't have anything to do with a DSLR.
Consumer are using Smartphones. Consumers like my mother, who do not use smartphones daily and prefer pictures over smart, use compacts when taking pictures in there holidays.
Hobbieists might use a Mirror Less instead of a DSLR.
Pros will still use DSLRs.
I still use my Canon 60D and prefer it that way. Having a mirror instead of a display makes it faster and it uses less energy.
Leica, just forget it. Its price is for the craftmanship not for the image quality. Ifyou have nothing better to buy, of course but don't do it for the image quality. it is very good but not worth the price.
