duckrider Posted February 16, 2017 Share #4  Posted February 16, 2017 Barnack Leicas had 1/30 sec for flash time, for some use this might be too long. So Leitz decided to create this lens using 1/100 & 1/200 sec for flash use. some additional info: http://www.leica-historica.de/VIDOM93_1.pdf  raaaaaaaaaaare item asking 5 digit price! http://collectiblend.com/Cameras/Leitz/Leica-IIIg-with-Compur-Summicron.html http://www.auction2000.se/auk/w.Object?inC=WLPA&inA=20130930_1754&inO=32  Thomas Link to post Share on other sites More sharing options...

duckrider Posted February 17, 2017 Share #7 Â Posted February 17, 2017 Advertisement (gone after registration) But I have another question: what is the piece mounted on top of the shutter button? Thank you! Compur-Summicron mounted You have to open two shutters: first focal plane of the camera, now in the second step compur opens & closes, now the camera's focal plane shutter has to be closed. Â All this needs to be coordinated in right chronology. Â For this the arm on shutter button is for. Â The rarest part -often missed when a Compur-Summicron is offered!
