I have been doing some preliminary testing with my Makina IIIR/Focal Plane Shutter, viewing the groundglass very sharply with my excellent Ednalite Magnifier. At infinity focus, with the tongs in the WA position, the 100mm F4.2 Orthometar is defiantly very sharp at infinity. So the question now becomes, using the rangfinder focused at various distances, and the distance then reset to the focal plane scale just under the front viewing lens, how sharp is image on the groundglass?? After some handheld testing at 1.5 meters, 3 meters, 5 meters, and 10 meters, EVERYTHING APPEARS SHARP THROUGH THE MAGNIFIER ON THE GROUND GLASS. I will retest again, using the Ednalite, but it appears I am golden. Next testing with be with Makina 8 shot backs, using 120 Kentmere 400, so I can achieve action stopping shutter speeds up to 1/1000, which is the whole point of using the focal plane shutter. One point I have noticed is that it is difficult to set the exact distance which I transpose onto the focal plane scale. It is very small scale physically and it is touchy to accurately set the focus distance. To not be in a hurry helps a lot! I think this is going to work for me, my camera seems to be set up properly to use this stuff. YAY. Time will tell. Now to find some test subjects that need to be frozen in time.
