Frequently asked questions
What's Bay III?
Bay III is the largest Rollei bayonet filter fitment - used on Rolleiflex 2.8 series cameras with the f/2.8 Planar or Xenotar lenses. Smaller Bay I (f/3.5 TLRs) and Bay II (Tessar/Xenar f/2.8) are incompatible. Rollei TLRs use bayonet-style filter mounting rather than screw-in threads.
