Are there any depreciation schedules for canon lenses?

Question

I am looking to purchase some used "L" series lenses for my Canon 60D. I am not exactly sure at which point it's no longer feasible to purchase a used lens over new. Surely even the best lenses must depreciate in value over time but I am finding that sellers are pricing their used lenses too close to the the price of a brand new lenses. Area there any good depreciation schedules out there I could use in my negotiations?

Answer

No, there is no such thing for any brand.

Lenses are one of the few things that generally increase in value over time. This is more true of high-end lenses. The cheapest lenses such as kit-lenses tend to remain cheap.

Major companies have been known to increase the price of lenses almost across the board. They tend to do it in small increments though but some jumps have been substantials.

Where I would expect a sharp decrease is when a replacement lens comes out (Version 2 or 3 with a new stabilizer or lens-coating for example) or significant change in technology (new mount, added stabilization, new type focus motor, etc).

Based on the last 30 or so lenses I purchased NEW, I can tell you that almost all of them now cost most then when I bought them. The ones I sold USED were ALL sold for more than I paid for, sometimes by only $50 but up to 3X the price too. I'm also keeping some worth about 6X their price now :)
