Hello i,m at the moment bidding on a Goertz 24 " artar apochromat lens, because i would like to use it on my 4x5 . It is of course a large and heavy lens for this purpose. How far (price wise) would you go with a lens like this. Or would you recommend a smaller long lens anyway. I hope you don,t mind this sort of financial question here.
