Rolleiflex 2.8C cold shoe

A cold shoe for Rolleiflex 2.8C (should also fit other models, but I only have a 2.8C and cannot confirm others; the circular base part is 29mm in diameter, 2.8mm thick). Replaces the regular film indicator inside the focusing knob.

The main advantage compared to cold shoe models that fit into strap lugs is that you can use it with ever-ready case.

I use a Doomo S light meter with it, but it should be compatible with any of those small meters with cold shoe mount. Rotates freely so you can use the focusing knob independently of metering.
