Overview

The Spiratone 135mm f/2.8 TC is a vintage lens often found in poor condition, as noted by Kevin Shorter on reddit.com/r/VintageLenses. Common issues include stuck focus rings, discolored coatings, stuck aperture blades (despite a 16-blade design), and balsam separation or fungus. When usable, it may serve as a preset macro lens, but optical quality is severely compromised by these defects. It suits collectors or those willing to attempt repairs, but not for reliable photography.
