If it were me, I’d do just what Canon is doing: (1) discount current RF lenses concurrent with the release of the new Canon EOS RP (see lenses below), and (2) announce a compelling lens line all due out this year, (3) announce a high-megapixel pro body in a few months. Canon has done the first two so far.
While the Canon EOS RP does not appear to be anywhere as nicely-specified a camera as the Nikon Z6 (video in particular), widening the price gap vs the Nikon Z6 by another $200 to the is a smart move at this juncture. And the fact is that for broad range of users, a price gap of $800 matters far more than anything else.
We now (or soon) have Nikon, Canon, Sony, L-Mount consortium (Panasonic/Leica/Sigma) all in the mirrorless market. Six players all vying for attention! And if Pentax wishes to survive in the camera market, it had better produce a 35mm and medium format mirorrless soon.
With all this competition, we should see a fantastic series of advances in the next few years in cameras and lenses, not to mention frequent price promotions.
Plus, my guess is that Sony is going to upend the game this year with some class-leading cameras, so that the other players will need to accelerate their plans, or look dated in less than a year of launching!
For years now I’ve said that the DSLR is dead. My premise included the inexorable rise of computational power that overwhelms any and every DSLR advantage for the few lingering distinctions that matter, such as certain types of autofocus. The DSLR is and has forever been a laughable failure with its lack of Eye AF, and now Sony has real-time eye tracking as the subject moves—computational power at work. I expect to see more and more of this, including a dream camera that can track the eyes of a deer or brid in flight or football player.
