The Okaya Optical Lord IV B is a solidly built heavy rangefinder camera made circa 1955. Though there is nothing radical about the design, the Lord IV B is a joy to shoot with. It has relatively long throw on the focus adjustment and uber precise feel to the aperture ring. It’s most interesting feature is the pull-out segmented rewind crank.
