hi
though disclaimer like buyers beware etc. and guidelines for describing condition of lens are published in the buy n sell forum, how do a newbie like me estimate the price of an used len?
All things equal,
1. what is the general useful life of lens? e.g. car is 10 yr by default.
2. can one spread the cost evenly over the useful life to agar agar the resale price if one know the age of the len?
3. would you discount or not discount the warranty (usu the 1st year oni) for qn (2)?
thanks for reading.
