I cut my teeth on fixed-lens VF cameras (Instamatic, Halina Paulette, '46 Franka 6x6 folder: didn't touch an SLR until a decade later, and an RF two decades after that. Therefore, my instinct and preference with all camera types is to scale-focus right off!
My current diet is mixed (SLR, DSLR, RF, P&S), although I try use one at a time. Based on my stable...
RF likes: no lag, no VF blackout, no motors, quiet, small. SLR likes: use of any optical rig (fisheye, bellows, supertele), no parallax, off-axis focussing.
