Judas Window!

[jamin-b]

I am trying out the Zeiss Planar 50mm on my relatively newly acquired Leica CL and just noticed a funny quirk - from the bottom right edge of the viewfinder the aperture readings on the lens are clearly visible, including the "12 'o clock", currently set aperture. Some might call this viewfinder blockage, but I call it a Judas Window just like in selected SLRs! It means both shutter speed and aperture are visible from the viewfinder...

LTM lenses often lined up at 11 or 1 o clock so you could look down on the set aperture - but this is fascinating.
