Talk: Zenza Bronica GS-1

The professional bellows hood came with adapters for 72mm, 82mm, and 95mm threads. This allowed it to be used with all lenses from 50mm through 250mm. This hood had a slot for drop in 4" x 4" filters. This reduces the cost of filters substantially as a lens set of 50mm, 100mm, 200mm would require three different sizes of screw-in filters.
