Canon 20mm f2.8 SSC FD BL Mount Ultrawide Angle Lens with a brand new Calumet 72mm Yellow (8) Filter for black and white. Lens is in excellent condition; no marks, scratches, fungus, etc. I'm just selling it to raise some cash. Comes with the rear cap only; the Yellow 8 filter is spotless. Note that this lens will only work on the Micro 4/3rds format with the proper adapter. $180 shipped conUS, payment by PayPal only.
