Steve, I agree with you.(posted 9249 days ago)I've only just got into 120 via a 645 Bronica using Delta 100 and Pan F. I've also had some negs on the thin side. I've not yet found the correct asa for me on either Pan F or Delta, but Pan F would seem to need about a stop more. I've also been using Rodinal and Ilfosol S.
