Join the crowd, Peter. I miss my M4 too, for the same reasons. Then. . . I think about developing film in the kitchen, swabbing it down, hanging it up to dry, cutting it into strips, making contact sheets, developing contact sheets, putting the strips into numbered spills and storing them, numbering the contact sheets, etc., . . . And all of a sudden I rush into my studio and hug my D3 and my D800.
