Of course! I'd wondered where it had all gone. Is that why old leicas are better? The phlogiston builds up insideand then illuminates the subject with even higher resolution when it's finally released! I suppose, if you want exposure consistency, you might have to trip the shutter at each speed a few times to get rid of the excess buid-up... All is becoming clear. I guess the choke control on the front of the barrel controls how much phlogiston gets back in... Mike But is the supply really permanent?... No its not, I had a model 3F with some pinholes in the shutter curtains. The Phlogiston slowly over time leaked out. I just noticed it , when the supply was run down to about a quarter. Leitz fitted new shutter curtains, and replenished my Phlogiston supply. By the way, you can not interchange the Phlogiston in the screw mount cameras with the one they use in the M cameras. The screw cameras use Phlogiston type XSA and the M models us type XMA. I just thought I warn you about this. It can be critical.
