Hi there,

I recently bought a few lenses and am trying to figure some stuff out, which made me turn to this forum after a while of being absent from the scene.

My questions are as follows for all the lenses listed:

• What is the circle of coverage?
• Is it worth shooting with?
• What is the approximate $ value? (wonder if I overpaid...)

Lens List:

1) Boyer 360mm F10 Apo Saphir
2) Boyer 150mm F4.5 Saphir
3) Carl Zeiss 80mm Planar in Graflex Synchro-Compur shutter
4) Goerz 1.5in (EFL 38.55mm) f4.5 Aerogor in Synchro-Compur shutter
5) Darlot pillbox meniscus (brass with 3 water-stop plates still in it and the lens is really much better looking than any I saw online)
6) Carl Zeiss Jena Tessar 21cm f4.5
7) Schneider-Kreuznach Xenar 24cm f4.5
8) Voigtlander & John in Wien und Braunschweig - this one is brass and has no other markings on it, missing the focusing crank, front element 2in and the whole thing is just over 4in in length

Any feedback on the questions above is appreciated
