Owner reviews: Spiratone 135 mm f/ 2.8 Tc
Excellent build, beautiful design and finish
Well balanced andnot too heavy (seems to be made of aluminum)
Buttery focusing with a perfect throw
Distinct sharp clicks of the preset aperture ring, excellent tactile feedback
Partially polished focusing ring does not provide secure grip
My copy came with the passport in the original carboard box in mechanically perfect condition but infested with fungus. Needs to be cleaned before I can comment on opical performance.
T-mount had KE bayonet (Exacta) adapter
