I've never compared them, but I wonder how ISO > 100 35mm film would do up against ISO 400 in 645 format. Any thoughts? My own experience was that the 645 format was better than 35mm under conditions similar to what you describe, which would have been shooting Panatomic-X in 35mm, and Plus-X in 120. At the time I was using a Nikon F2s for 35mm, and a Bronica ETRs for 120. The Nikkor 50mm f/1.4 and Zenzanon 75mm f/2.8 were both very good lenses.
