I also still have a Retinette and a Minister in some drawer … fond memories

Or it is we're living in the same house ;-)

>> Let me back up a moment.
>> 
>> I was taught that a “normal” lens is one whose focal length matches the diagonal of the film/sensor frame.
>> 
>> For 35mm film as shot by, say, a Leica M6, that turns out to be 43mm - midway between a wide 35mm lens and a 50mm lens which I have sometimes seen called a “short telephoto” perhaps even by B&H.
>> 
>> Now as I remember from my cinema days 35mm movies are shot at the same aspect ratio as still but have different dimensions since they are shot with the long edge running across the film instead of the short edge as is the case for full frame 35mm film photography (except, I’m guessing, half-frame 35mm but now I’m totally out of school having never seen one of these cameras.
>> 
>> That’s where I’m coming from. And wondering why we don’t see more 40-something focal length lenses. I know that there 48’s out there? Nikon maybe from the old days? Mark Rabiner, you talked about this at some point, I think.
