Way back in the early days of the Camerosity Podcast, we did a show with Canon historian and author Peter Kitchingman, and recently as the gang looked back at what topics were worth revisiting we decided to come back to Canon rangefinders.  But what expert would we get this time?  As it turned out, Peter was available and willing to come back so we decided to retread this bountiful topic and deliver a "Part Deux" to Canon rangefinders.Joining Peter and the regular hosts were Greg Harp, another excellent resource for these cameras who has a great deal of knowledge, plus listeners A.J. Gentile, Ben Ryerson, Ira Cohen, Jeremy Scott, Joan, John Roberts, Norris Liu, William Smith, and Will Pinkham.We start off with some brief history and then get into some of the earliest Canon rangefinders like the original Canon and the slightly later Canon J and JII.  Moving onto the historically significant S, SII, and IIBs and eventually covering the II, III, and IV series.  We move along to the back loaders like the V, VI, P, and 7 series, covering various lenses, including the 0.95 Dream lens, a very rare original Canon mount wide angle lens, and others.  Greg and Peter even share a bit of knowledge about Canon's X-Ray cameras which they made during and after the war.Although a majority of you probably wanted to hear the most about the interchangeable lens models, we give some love to the fixed lens Canonet models like the trigger wind Canonet, the Canonet QL17 G-III, and even some of the more economically priced models.Unusual to a Camerosity episode, we largely stayed on topic for this only only slightly veering into one Argus lens (blame Mike for that), but we answer a bunch of questions such as why is having different magnification ratios for the rangefinder useful, why is having separate viewfinder and rangefinder windows better, and what role did Nippon Kogaku play in Canon's history.As always, the topics we discuss on the Camerosity Podcast are influenced by you!  Please don’t feel like you have to be an expert on a specific type of camera, or have the level of knowledge on par with other people on the show.  We LOVE people who are into shooting or collecting cameras, no matter how long you’ve been doing it, so please don’t consider your knowledge level to be a prerequisite for joining!The guys and I rarely know where each episode is going to go until it happens, so if you’d like to join us on a future episode, be sure to look out for our show announcements on our Camerosity Podcast Facebook page, the Camerosity Discord server, and right here on mikeeckman.com. We usually record every other Monday and announcements, along with the Zoom link are typically shared 2-3 days in advance.Our next episode will be number 110, and we listened to you all for a topic and you chose 110 "Pocket Instamatic" cameras.  This means the Pentax and Minolta 110 SLRs will definitely make an appearance, but in the event we can't fill a whole episode about 110 cameras, we are opening up the discussion to all 16mm subminiature cameras.  We will record Episode 110 on Monday, June 8th at 7pm Central Daylight Time, 8pm Eastern Daylight Time, and 6pm Canada Saskatchewan Time.  For more time zones, please consult the World Time Buddy calculator and plug in your time.  Make sure you set your calendars and look out for the show announcement at the usual locations and be prepared to join us!In This EpisodePeter Kitchingman is Back / Peter Still has Hundreds of Copies of His Book for SaleA Show Listener Recently Picked up a Canon JII and Asked What it WasThe Origins of Canon's Early Models / Rangefinder Less Canon JNippon Kogaku's Role with the Early Canon Cameras / Serial Numbers are Difficult to TrackCanon J-Mount vs Leica Thread Mount (24 tpi vs 26 tpi) / The Canon SII Was the First LTM CanonCanon Remained Profitable During the War Making X-Ray CamerasMike Thinks the Rotating Prism Was One of Canon's Best FeaturesWhich Canon is Good for
