On a Hassy, press the shutter and
1. mirror goes up
2. shutter opens, then closes
3. mirror stays up until film is advanced and shutter is cocked
On a SLR with instant return mirror, press the shutter and
1. mirror goes up
2. shutter opens, then closes
3. mirror goes down even with film not advanced and shutter not cocked
With a Leica RF, press the shutter and...shutter opens then closes...since you do not SEE THROUGH the lens on any rangefinder camera!
Confirmed but
You have not addressed the phrase
'with the sun in corner of frame'
which I did quote.
It is normal to miss context and not in my text.
