Has me wondering whether equivalence works similarly to digital, i.e. would you have gotten similar results (also in terms of resolution, etc) shooting e.g. Kentmere 400 @ 1600 at 1/125 f2 on 35mm.
It probably would have been a lot grainier with 35mm; I don't think ISO 1600 would have worked even with a fast lens (I have a few f1.4 lenses in 35mm). The meter reading and thus the range of possible f-stop and shutter speed combinations would be the same for 35mm vs. 120, but depth of field is different and of course resolution is higher in 120 (and grain is usually much less evident).
Delta 3200 is really an ISO 1000 film and its box speed of 3200 is achieved by pushing. From everything I've read, DD-X is the best developer for shooting this film at ISO 3200 and so far it has worked well for me, following the development times in Ilford's data sheet for this film. I also followed the time for pushing to 6400 but the negatives were pretty thin; I'm going to try the other roll at a little more than 13 minutes instead of 12.5.
