For the past several years I have been using both the Canon 500mm f/4L IS and the 300mm f/2.8L IS for long lens work, primerily wildlife.
I have found though that the 500 is too large for easy international travel, and the 300mm not long enough for the type of shooting that I am doing. So, I have recently sold the 500, and now am selling the 300. I intend on replacing the two of them with the Canon 400mm f/4 DO IS.
My Canon 300mm f/2.8L IS is now for sale. It is essentially perfect mechnically and optically and a 9.8 cosmetically, and comes complete with its original fitted case.
B&H currently has them new for US $3,899. I want US $2,899, and that includes shipping by Fedex to anywhere in the world. (Taxes and duties, if any, are your responsibility).
I will accept a bank draft or bank transfer as payment.
If you're interested in this lens, drop me a line.
