Thanks, good to hear that the meter can be trusted.
Yes - I develop my BW films. I use the dedicated opener to get film from the cartridge, so that should be OK.
I was already thinking of the 90 lens as I know I will have the use for it (I use the 150 for my Mamiya 6 rather often), but I have decided to wait and see how I get on with the XPan, before spending any more. Right now I am targeting the lens hood
I hope that latest on Tuesday I will have the camera in my hands. Optimally I would manage to get through 1 films before the vacation to be on the safe side.
