Heya (great new forum topic!)
I'm new to large format and plan to build my own 8x10 in the near future - learning on the way first by making a 4x5 which I have bought an old Zeiss lens for (I am also plan to use a Rodenstock enlarger lens as well) ...
I am too busy to start work so far but have been offered in the meantime a selection of old military lenses that may or may not be good for an 8x10 - does anybody perhaps recommend any of the following ? :
- Zeiss Jena Tessar 'XII' APO 64cm F10 - ~90 No. 625245 - the cement(?) between the two rear elements is separating a little at one edge, but by stopping it down to about f16 it is no longer 'seen'
- Unbranded but seller suspects either a Cooke or Taylor-Hobson 5" f4 - ~32 No.158157 'ree 14A/1101'
- Unbranded again and again suspect its a Cooke or Taylor-Hobson ANASTIGMAT 14" f5.6 - ~128 No. 280729
All have the 'A~M' logo on them which I think is something to do with 'Air Ministry' / Air Force - they were apparently used for aerial photography, and are probably pre-WWII era...
I am after a wide lens, which puts the Zeiss out of the picture, but am wondering if the 5" is either too wide or would not have the coverage for 8x10 ? (it is a smaller lens also) - Altho not wide for 8x10 is the 14" the safe bet here ?
As I mainly deal with long exposures (minutes+) I usually am stopped down quite a bit, does this affect the size of the image circle ?
What sort of worth are these lenses ? all clean except Zeiss (see above), no shutters - if the Zeiss APO is a good price should I just buy it on principle ?
A heap of questions there - looking forward for any help - hope I can return the favor one day
