Hello, I'm scoping out the LF arena before taking the plunge, and was reading Wisner's article on vintage lenses for 8x10, goerzes, b&l's,etc. So I was wondering if anyone uses these kinds of lenses for 4x5, on a regular basis, and how they compare to modern glass. They don't have to be old old, I'm just attracted by the lower weight and price of even wollensaks and xenars from the 50's. My other option is going with recent vintage caltar/rodenstocks, heavier and a little more expensive. Thanks for the help.
