Further to my post (there was a url link here which no longer exists) , what is the dfference between the Carl Zeiss Softars I, II and III? I assume they vary in strenght, is to how much they fuzzy the image? But I can't seem to find a detailed technical write up of how they work, what their designed usage is etc? Anyone any info, or better yet, a side-by-side image set to show the same scene shot with a I, II and a III?
