Trying to find info (Value) of a macro lens I got with a camera. It is a Canon macro lens ef 100mm 1:2.8, it doesnt have the switch on it like the newer ones, so I know its a older model. Says made in Japan
Looks like they go for a little under $200 on ebay. Production started on these in the early 90's, not sure if there is an easy way for you to find out when yours was produced.
