Nice one! I've seen and actually used one of these meters (albeit briefly) but baulked at the price (£170-ish in the UK) as that was more than the camera cost. Stupid logic really as the meter is the thing that will make sure that the exposure is where it needs to be. Maybe I'll ask my wife for one as a Christmas present.
I also like shooting wide open. Autumn, winter and spring offers good opportunities for that over here as the light intensity can be very low when it gets cloudy. Incidentally, I've tried leaving the exposure settings untouched when a cloud passes the sun and had mixed results; it is less of a problem when it's not the height of summer and slower film seems less problematic than 400+ ISO.
I had a Mamiya 7 some years ago, so I presume the meter will be similar to the 6? I really liked that camera's results but I used it, almost exclusively, on a tripod (landscapes). Bad move - you have to take the camera off the tripod and remove the mounting plate to get the door open and change film. What I didn't know (until too late) was that Mamiya brought out a little widget thing that sits between the camera and the tripod specifically to allow the door to open whilst changing film. Maybe one day I'll get a 7 again (or a 6) as I'd like to shoot that sort of quality camera hand-held now I'm doing more travel and reportage / documentary stuff.
Thanks for the info and insight; always great to hear other guys' "tricks of the trade".
