Is anyone able to advise me regarding the use of this casket set in particular, the between lens #1 is missing, how do I focus without this? is it ok to focus at the stopped down taking aperture? I think I recall something about the spectral response of modern films being different to the plates/films contemporary with the Vademecum set and that the 'between lens' are not required? maybe Ole could help, I have tried his Casket set Website to no avail.
A definitive answer would be greatly appreciated
