Probably a silly question but... Let's hypothetically say a lens without the original box but has flawless glass and it comes with it's retaining ring and "original branded caps" and it's worth $200. This could be a Scneider, Nikkor, Fujinon, Rodenstock... whatever. Don't consider this as a "highly collectible" lens. This is a very nice user lens in exc++ to mint- condition. 1. What if it has "no caps" but will be shipped with wrong-fitting covers just to protect the lens during shipping? How much will this affect its value? 2. What if it comes with "fitting caps with the wrong brand label"... say a Schneider Xenar lens with Canon or Vivitar caps? 3. What if brand new caps are bought... "perfect fit and no brand name"? My guesses: 1. Lens devalued to $135-150. 2. Lens devalued to $155-165. 3. Lens devalued to $170-180. I'm asking this because I have about a 100 lenses that all need caps. They're carefully bagged and stored/protected but I'll be selling them soon. Push-on lens caps average cost is approximately $10 each. 100 lenses at 2 caps/lens is 200 caps. 200x $10 = $2000 just for lens caps!! The Scneider lenses will all have Schneider caps. All other brands will have either Schneider or generic caps. That's a LOT of money but even if I break even on cost I'll bet I make my money back and the lenses will sell faster. Most of the caps I have are non-fitting off-brand only good for protection during shipping. Thoughts please? Think about how you shop for lenses and how this affects your offer price.
