The Cost of Good Glass
Professional camera lenses rarely depreciate significantly, making the used market highly competitive. When sites like KEH or MPB list a popular lens in "Excellent" condition for a great price, it is often bought by resellers within the hour.
Precision Tracking
You need highly specific alerts to avoid buying the wrong mount or condition.
- Mount Specificity: Ensure you are only alerted for Sony E-mount, not Canon EF.
- Condition Grading: Filter out "Bargain" or "Ugly" grades to only see pristine glass.
