I have a Canon 75-300mm IS f/4-5.6 lens with off-brand (Asian) lens hood and 58mm UV filter. I received it in part of a package deal, but I don't have a need for it. I was hoping to trade it for a sharp Canon 2x II teleconverter.
Other things I might be interested it...
--Kirk Mighty Low Boy tripod
--A large backpack that can house a DSLR attached to 500/4 lens...that is also permitted as a carry-on for airlines
--monopod with tilt head for usage with 500/4 lens
