Schneider 80mm f5.6 Makro-Symmar HM, aka Apo-Digitar M-28° (making it a superlative digital lens), Multicoated, Copal 0 shutter, 28° angle of view, 100mm image circle at infinity (141mm at 1:1), MINT, ships with both caps and retaining ring.

NOTE: This lens is NOT marked Digitar, it is marked Makro-Symmar HM as shown in the photo. The lenses are essentially identical physically, mechanically and optically. Schneider rebranded the Makro-Symmar HM as the Apo-Digitar M (macro) with the advent of digital photography (which they actually did this with several of their lenses).
