Once more, the forum has bit me!! Started reading this and had to go find a copy - ran across one on eBay and bought it! Dang!

But, thanks for finding it and bring it to our attention.

Excellent jsherman!

Please keep on posting pages from the book! I like the coffee stains also :-)

About the normal lens use, here's some more readings to consider, specially the first page of these documents discussing general design intentions,

50-60mm lenses: http://en.leica-camera.com/assets/file/download.php?filename=file_1887.pdf

Jay, My copy is in pretty good condition. It's been well used over the years but no coffee stains. Great reference book though.

George, thanks for posting that table, filed away for reference.

Here's some more info from 'The Manual' for all you camera geeks:

Damn-it Jay. I glued pages 1-10 and 1-11 together to avoid looking at those old chrome Taks. I want them all just to have. I don't care if they suck optically but I bet that 135mm would look great on a black body. Kinda like the cars of the 50's with all that shiny stuff.

Now you reminded me of something I really have no use for but want. Thank goodness they are impossible to find.

Now we know what they were going for with the FA chrome ltd lenses.

Damn look at the size of the box camera that woman is holding!
