Old SLR cameras had a ring around the lens for f-stop and another dial on top for shutter speed.
New DSLR cameras even now hide all that stuff in a menu on the touch screen, as if it isn't something you want to change ALL THE TIME - and develop instant muscle memory for.
Never mind us older folks, who often have vision problems with up-close viewing, which is a solved problem when you can spin a shutter or aperture wheel by touch. But not when you need no-glasses to view the objective, but reading glasses to view the fine print on the screen.
(although i've never understood why it has a tach since its a manual anyway... but i guess i can close my eyes and imagine my V6 ranger is a corvette...)
Most "pro-sumers" wouldn't bother to adjust what the auto-focus calculates anyway.
I was using those dials all the time as a 16 year old learning to use a camera. It's really easy - especially when you can set one of them to auto and just control the one you care about - plus so quick when they're on a dial.
But I can believe no one wants to do it now, it's amazing how much a bit of tactile feedback can make a task 100X easier, and something you can do instinctively.
I think that is the 'sumers. The prosumer gear is for people who actually want to play with all that stuff, but don't want to pay $10k for a pro body and lenses.
Someone correct me if I'm wrong and tell me where to buy one!
As with anything camera related, where to buy could be B&H, Adorama, Sammy's, or your local camera shop (if they still exist in your area).

Who knew a few physical dials would be so expensive...
Don't approximately all DSLR have separate physical knobs for aperture and shutter speed?
Agreed that a DSLR without these would be nearly useless.
