This is an old thread I dug up to avoid opening new ones. After reading all the posts in it, and now some time has passed, does anyone know of a feasible direct replacement for the bulb in the top-mounted Graphic finders and the Kalart Focuspots? My complaint is that in many instances the normal bulb filament is just too dim. Given a nice bright beam on subjects can translate to a true point-and-shoot camera without having to do anything more than holding the camera up and giving nothing more than a cursory glance through the pull-up sportfinder, and click.
