The OM-3’s new CP (Computational Photography) button consolidates every computational feature into a single dial-controlled menu, freeing up four programmable buttons and making the camera more usable than the OM-1’s eight-button setup in practice. Five named custom settings, a separate video mode dial, and a combined body-plus-six-lens kit weighing 1,287g — less than a single Sony 200-600mm zoom — make it, in my view, the best urban and travel camera available.
