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. The filter is in excellent condition with clean scratch-free glass. It is slightly loose in the mount but this does not cause any problems. It comes in the cool vintage leather case.
