The amount of information in Peter's book is staggering. Anyone seriously interested in Canon lenses should have this book.
I own the Canon 100mm 1:3.5 Type 7 listed in the book as the highest serial nunber for this lens. However, Peter told me he later found out about an even higher number after the book was published. Anyway, a couple of corrections need to be made for this listing. The Infra-red (R) mark on my lens is red and not orange. Also, the Focus Range on my lens is 3.5-50 not 3.5-60. Minor technicalities.
Once again--a great book.
Are we having fun yet?
