Great article!
My only comment is I would refer to short lenses as "short" just like you did for long lenses. I find newbies often get confused with the term "wideangle" as it is used in 35mm and medium format, versus the LF lens' stated angle of field. I would also probably then add a paragraph on lens angle of field and how it corresponds to image circle to further clarify the distinction.
Cheers,
I second "good article"
A couple of minor issues:
The hole in the lensboard is sized for the shutter, not also the rear element.
A 300mm telephoto needs about 200mm bellows, not 270mm.

Nice article. I have noticed a few Congo lenses labelled as Yamasaki Optical. Perhaps that might be something to add onto the article.
Ciao!

Thanks for the comments. I will track this thread in the future if there is ever a third edition I will take them into account.
Another "niggle":
The classic convertible lens is not the "Bausch & Lomb Protar", but the "Zeiss Protar Serie VII, also produced under license by B&L, Ross, and others".
Apart from that, well done indeed!
Nice!
Nice article. Keep up the good work.
Edits: The pic of the "72mm" lens is really a 110mm lens. And, Rodenstock also discontinued the Apo Sironar W lenses, of which the 150mm is a must lens for 5x7.
Nice read for me. Thanks.
A question, does any LF shutter has a self-timer? and also, you didn't mention polaroid shutter in the article.
