[Leica] Erwin Puts farewell to Leica World

[Mark Rabiner]

I've always had a fascination with the infinity symbol ∞ on my first camera I got in 1965 with f stops and shutter speeds when I was 12 or 13 it was a mid 1950's Voigtländer Vito BL. I was not sure what to focus it at infinity on it seemed like it should be a long way away maybe I should pack a lunch. No hills in the north shore Chicago suburbs to speak of.
There was no internet to look it up there was no one to ask and the Dewey Decimal System was not doing me any good in the Winnetka and Glencoe library's.
So I settled on clouds. I decided clouds were infinity. I aimed at clouds when I adjusted the eyepiece on my camera for years. Decades.
Erwin may have noticed some of my occasional infinity posts on the LUG and did a thing on what  ∞ (infinity) means in photography on a real level like how far way is it really.
Turns out its not all that far away you don’t even need to bring your lunch!
The focal length of your camera times the square root of the hypotenuse that kind of thing... couple of hundred feet away - piece of cake.
You need to know how to to math though or how to use a slide rule. Or Geometry. Or trigonometry.  No biggie, just way out of my pay grade.
Clouds may be bit fluffy though for accurate focusing but they've all I've got; on a cloudy day.

Here's one right next to a Leica M2!

    Which is unlike most of the companies.  In my pre-Leica days, I became
    frustrated returning lenses that focused at different places for the
    different edges of the field.  I have a mountain ridge at "infinity" and
    clear air where I live.  The poor assembly of the middle market optics was
    very obvious and frustrating.  We do get something for those prices we pay.
