Tomosy’s 4th book consists of only five chapters:
Rangefinders with lens shutters
Rangefinders with focal plane shutters
SLR’s with focal plane shutters
SLR’s with lens shutters
Medium format.
Many classic cameras are covered, none of which were in his previous books. And… he covers these more thoroughly than in his previous books. There are approximately 40 cameras covered.
Tomosy couldn’t resist wasting several pages repeating basic repair stuff from his previous books. Are these meant as tempting commercials? I would have preferred he cover a few more cameras.
