What a nice feeling, when I just took my Mamiya 645 from storage and now I feel so at home with split prism manual focusing and a mechanical camera that just keep going. What a surprise when the meter battery, 4LR44 was still functioning after more than 10 years in storage. This is a quality camera and the only thing that has kept me from using it, is the film format, 645, quite tiny. And of course digital is so fast and lazy.
