Inside the R-D 1 rangefinder < Previous | Back to index | Next>

This front view shows how the frameline selection system works. The framelines are thin lines cut into a mask. A slotted plate fits over the mask; it moves so the slots uncover only the lines for the framelines you want to use. This whole assembly fits behind the front panel's frosted window, which provides diffused illumination that passes through the frameline mask and is reflected into the finder. The small circuit board at the bottom of the mask is the shutter speed readout.
