Camera bag for the Mamiya RB67 Pro-S

The RB67 Pro-S measures 104 × 144 × 228 mm at 2705 g (Width/Height are body + revolving adapter + focusing hood + Pro-S 120 roll film holder (no lens, per manual's own dimension breakdown). Length/depth and weight figure used here additionally include the standard Mamiya Sekor 90mm f/3.8 lens, since the manual's spec sheet only gives a body length measurement in combination with a lens (228mm w/ 90mm lens, 217mm w/ 127mm lens); weight = 1450g (body+adapter+hood) + 450g (roll film holder) + 805g (90mm f/3.8 lens) = 2705g.). We test that box against the published interior of every bag in the catalog.

Film lenses vary too much to assume one — verdicts below are for the body alone. Add your lenses in the fit checker mindset: a body-with-lens needs meaningfully more room.
