What it is
{"overview":"The Cosina 40mm f\/2.5 is a compact wide-standard prime lens from the Japanese maker known for producing affordable manual-focus optics across multiple SLR mounts. Check the aperture blades for oil migration, confirm the iris snaps cleanly between stops, and turn the focus ring through its full travel to feel for stiff, dry or sticky helicoid grease.

Questions
What should I check before buying one?
Look for fungus, haze, oil on the aperture blades, coating scratches, element separation and stiff focus, as these are the typical failure modes on Cosina primes of this generation.
