I see all kind of lenses, and don't know what it means to be a Series IV or V or III, etc.
Is a Series IV the same in some characteristic across makers and formats?
As an example, I just bought a Grunlach 11x14 Series IV f6.8. Why don't they just tell you what the focal length is?
I assume the 11x14 part means it is intended to cover that format. Is a f6.8 Series IV a normal lens, a WA, what.
Can I transfer any of that to the Plasmats Dagors or others?
Does anyone know of a link to a data table, that has Maker and Series on one axis, and format/max aperture on another, that would indicate FL and image circle at mid-aperture (Boy, I'm not asking for much am I).
I would appreciate any help I could get. Thanks.
Kind regards,
Michael
