Selling this Canon EF 100-400 f4.0L IS USM w/case, Hood, all caps and tripod ring. It is an EF mount/full frame and in EX+ condition. Reason for selling is the lens is just too heavy with my Canon 6D. Used very little and not taken on any trips because of the weight. Asking price is $815, which includes shipping and insurance. Serial number is 580775. Only CONUS and PM me with any questions. Paypal accepted.
I'm not aware of Canon ever making a 100-400/ f4 ever, I only know of the 200-400/f4!
