(Should have added) - The Fuji 125 is in somewhat more demand than the 135, so tends to fetch higher
prices, but is also more common. I have the 52mm filter version, which is popular with landscape photographers due to its small size. Nearly the same coverage as the 135, and slightly more coverage than the equivalent Nikon lens. Very very sharp. The current version (CMW) requires a 67mm filter.
Anything in this series in clean condition below $300 would be a steal.
