I've just obtained a couple of lenses. The first is a (single) coated Som Berthiot 1:10 F=300 Apographe lens. I've looked in The Vade Macum and the Apographe is not mentioned. I know that it's a process lens as it has a slot in the barrel for Waterhouse stops. It has a working diaphram as well. I assume that it's post WW2 but it is mainly brass and looks older. Will this lens be sharp and is it worth bothering with?
The second lens is a TT&H Cooke 13" / 330mm Series VB, not Vb, process anastigmat lens no.285133. The Vb is mentioned in The Vade Mecum but not the VB, are they the same lens? There is no slot in the barrel am I correct to assume that this lens was adapted for normal use by TT&H? I have a couple of Cooke lenses so I know that it will be sharp, no problems there.
Thanks for any advice you can offer,
Pete.
