Here's the background;
I still LOVE Verichrome-Pan B&W film, especially by today's film standards.
It's loaded with silver & has a great range of Grey-Tones,
even without using the Zone System.
Verichrome-Pan B&W film is still available on eBay.
But 620 is in much greater supply, than 120 film is & it's priced much lower.
I also know in order to still use 620 cameras, people routinely re-spool,
120 film on to 620 spools, due to the smaller core of the 620 spool.
So this tells me the film dimensions are the same.
I WILL NOT RE-SPOOL ANY FILM !
So, can I use 620 film in a 120 camera, as it is from Kodak ?
This will be used in a Mamiya RZ camera, not that this matters, much.
I'm sorry if this question has been asked before.
