Yes, DSLR's are being phased out. That is a fact
Other facts are
Mirrorless cameras are so far superior to DSLR's at the same price points. They focus faster, better video, and are smaller
The adapters make it so the millions of lenses in the marketplace can be used and you don't get hurt having to invest in new glass. You lose NOTHING!!!
Cameras like the Canon M50 mark II, Sony A6400 and the Olympus E-M10 mark 4 don't break the bank but have so far surpassed DSLR's on the market feature and quality wise i comparable price points.
BIGGEST FACT... There is NO cell phone that compares to ANY mirrorless or DSLR on the market when you look at a picture printed 8x10 or larger. We print all day long and people that have the latest cell phones come in thinking they can make 8x10's and when they see there perfect picture on their phone screen and the grainy picture that actually gets printed and then see the display we have showing the sensor sizes they understand.
