Vivitar (Kobori) 70-210mm f/4.5 Macro Focusing Zoom MF Lens | Pentax KA Mount | VG/EX/G

Item Description and Condition Details.  This listing includes a manual focus Vivitar 70-210mm f/4.5 Macro Focusing Zoom fitted with a Pentax KA mount, a genuine Vivitar lens cap, and a genuine Vivitar mount cap.  This lens was manufactured under contract by Kobori (Japan).  The condition assessment for this example is broken down into the three major areas of interest, cosmetics, mechanics, and optics, and discussed below. 

·         Cosmetics.  Very Good Condition.  The following issues are noted:  slight wear (loss of coating) located along the front facing edge of the focus/zoom cuff; light wear to the coating of the knurled metal on the aperture contro0l ring; a few areas of coating loss along the front facing edge above the lens filter threads; wear encircling the lens on the edge just above the aperture control ring.  The lens surface, including the textured grip, is clean. 

·         Mechanics.  Excellent Condition.  The following issues are noted: although fluid, there is a drop in force midway through the zoom action in both directions (no grit, plus as the lens was exercised, the force drop reduced dramatically and may disappear completely upon use); slight wear on the end of the aperture control pin.  Aperture is snappy and the blades are oil free.  Mounting flange is clean and shiny

·         Optics.  Good Condition.  The following issues are noted:  minor internal dusts; the slight haze on the front of one of the interior elements (it may be accumulated dusts).  Outward facing glass is undamaged.  No fungus, separation, or debris present.
