Hi, Steven. Thanks for the response. Yes, I've read a bit around here on some threads on Suter lenses, and many state the 4+4 configuration. In fact, I stumbled upon a pdf copy of the "Yearbook for Photography and reproduction technology for the year 1901" (german: "Jahrbuch für Photographie und Reproduktionstechnik für das Jahr 1901") where they describe "Suter's new double anastigmat, comprised of two symmetrical halves of four lenses each". That just about clears it up on the design and that half of it is in fact missing. From the drawing, I can say the front element and the mounting flange are no more *poof*.
So, I know what you mean with the lens at the back. I happen to own a convertible Symmar 5.6/135mm lens, where you remove the front group to get an 1:12/235. Almost double the focal lengt, so this could be around f14.4/660mm with only one lens group. Upon further reading the small article dedicated to this line of lenses on pages 72-73 states that "Each of the lens halves (groups) delivers even at full aperture a sharp and even image at double the focal lenght of the double objective".
I'm attaching the article, including the drawing and the table describing the whole lens lineup. It even has prices on it! <3
. Steven, I hope this brings you some more relevant information on the lens you own, and to others in the future.
If anyone is interested in the whole translation, please let me know (I'll just write it in a whole new post). I'm also interested in putting up a wanted thread for the front (or just another rear element) and maybe the mounting flange for this lens. Can anyone point it out for me, please?
Cheers!
