As I understand it, if the light leaking from the rangefinder is
enough to give an average exposure of 1/15 second, as measured
off-the-film with a lens-cap on the lens, then it will create visible
fogging when the lens-cap is off at faster shutter speeds. So even at
1/125 or 1/250 it will show.
I didn't know about a redesign: this may be an issue. The camera was
bought in UK in June 200 and was new stock as the shop had sold three
Hear RFs already. My guess though is a bit of felt was missed out when
it was assembled.
