Recently, I've seen a few Japanese quarterly sales listings where the Nikon D7500 is still fairly popular. Everything else listed is a mirrorless camera or the latest version of the Ricoh GR.
It's interesting to me that things have changed so much in 16 years.
When Panasonic introduced the G1, no one was sure what to think. For me, Panasonic had only recently got into interchangable lens cameras with the DMC-L1 that was announced with the Leica Digilux 3 and the Olympus E-330. They had no real history in stills photography before 2007.
I waited until 2012 to trust them with my money and I wasn't completely satisfied. By 2014, Olympus' E-M1 arrived and I could see mirrorless cameras pushing out dSLRs eventually.
Being that Pentax doesn't have any mirrorless cameras now, and those they tried were awful, will they go away?
Nikon and Canon seem to have a new model or two every few months. Their first 135 Format models were setbacks for mirrorless cameras in general, they are finally finding their way with third generation models. They both have a few dSLRs available, mostly in the bargain basement.
I don't believe I'd used a dSLR since 2016 and that was a necessity because the Olympus E-M1 did not cooperate with my Four-Thirds lenses and micro Four-Thirds didn't have the focal lengths I needed.
Imagine people from the 1970s, when ASA(ISO) 400 film was new, being shown a modern camera body that is huge in contrast to the typical SLR of the time. Leica users, though, will probably be at home for the most part because of the M-series. Don't show them the L-mount bodies.
Do you think by 2030 that dSLRs will only be part of the used camera sales?
