I just finished hanging four more rolls, which I just ran together. Two rolls of 5222 XX, and two rolls of 5231 +X. Developer used this time was ADOX Borax MQ, in a four-reel metal Honeywell Nikor tank. Temperature was 21C (ambient), developing time was eight minutes, agitation was fifteen seconds initially, then five seconds every 60 seconds. My ADOX is about three months old at this point, and I haven't used it in awhile. I wanted to see how it would do with +X, and the XX rolls were important to me, and this is my favorite dev so far.
All frames look great (as usual) I'd guess I'm getting about 100EI from this combination with the +X. As exposure is increased slightly, shadow detail is amazing, while still not burning out the highlight values. Detail is incredible. I -really- like this +X Movie Stuff, and the important XX rolls also look fabulous, which I completely expected.
I loaded two more fresh rolls of each, XX for M5, and +X for M2. Getting great results from all of these. Tommorrow my new 85mm f1.5 Canon arrives, you -know- I'll be out playing with that with both bodies!
