Rollei Rolleisoft 1 Bay I Soft Focus Filter -Read, Small Coating Wear-
This is the mild #1 soft focus filter in Bay I size, which fits the f3.5 Planar and Xeontars. It is a duto style filter, which leaves the center sharp and gets gradually softer toward the edges.
It is in good condition with moderate wear. There are a few patches of coating wear near the edge of the glass on the front element but they will not affect your images except in especially harsh conditions and may add to the Rollei soft effect. Otherwise the glass is clean. The mount shows light wear.
