Someone gave me a second hand Minolta range-finder at age 11. No manual, no Google, no money. I learned DOF, shutter speed, motion, flare, sharpness and film speeds by myself at a time when you had to WAIT a week for your photos. Colour was expensive! . Since then, I've always had trouble putting a camera down and have had well over a hundred cameras including a much-loved FULL frame Mamiya RB-67 outfit :) . I have been semi-pro for decades and see micro four thirds as a great compromise. Pro results without much bulk and weight means rarely I leave my cameras behind. . Years ago, I recovered from "Equivalence Phobia" that so many suffer from, and find that people react better to a smaller setup and love the results. . Customers want results, not "format psychobabble". . Enjoy your photography instead of making silly format arguments!
