Camera Lens Testing

Lens Condition? Bob Atkins has an interesting blog on how to evaluate how a lens is working and its current value/quality. This is great information to have in your intellectual kit and will be of service when you buy new or used. Personally, I have made some great buys in the refurb/used market, but it really helps to know what you are getting into by having a great knowledge file to draw upon.

Note the blog history on the left side of the article for even more good information.
