I'm trying to find of the technical data for one of my Sinaron Lenses, particularly the size of the image circle. I have a Sinaron W 90mm f/4.5 with a 102 degree angle of coverage. The lack of technical data becomes an issue with the 102 degree angle of coverage. All of the data I can find are on the later Sinaron lenses with a 105 degree angle of coverage. Does anyone know a source that has all the Sinaron lenses listed? Is the 90mm Sinaron W with 102 degree angle of coverage really rare? I only ask because the only other Sinaron W 90mm that has a 102 degree angle of coverage (that I have found at least) is an f/6.8.
Any input would be appreciated.
