My RF patch had the 'ferns' and all was fine until one day, outta nowhere, it came apart. Wasn't hit or anything like that either.
I thought my perfect condition CLA-d 135xxx M5 was super smooth until I compare it to the M-A. Difference between old and new so not surprising.
You're right about 120 film. Nothing in the 35mm world can compare. it's more about convenience and speed.
edit I just got a note back from DAG. It seems that when my M5 was 'upgraded' to included the 28mm frame set, the tech put in the pre MP one. Which is freakin' messed up seeing how much I paid for that. Apparently some old ones were lying around... The cost to put in the correct one with the non flaring items is the same as what I paid for the crap ones. Never again will I use that tech. I even asked that tech about it as I noticed it the moment I got my camera back, but was stone walled...
Anyway, back to my happy place! I love the M-A!
