A small handheld light meter with a built-in laser rangefinder would be very handy for Minox users. The rangefinder would only need to be able to measure from 8 inches to 12 feet. Take a reflected light reading and measure distance to subject at the same time, or take an incident light reading and then measure the distance separately. Of course, the measuring chain is likely to be easier to use within 8 inches to 2 feet.
