Here is a Sigma 150-500mm f/5-6.3 APO DG OS HSM Lens for DSLR cameras with a Canon AF lens mount in excellent used condition. I've used this lens with a Canon 7D mkII and produced some excellent results at this year's British Motorcycle Grand Prix. This is an ultra-telephoto zoom lens ideal for nature, wildlife and especially sports events. I fitted a Sigma DG UV 86mm filter from new and the lens comes complete with original carry case, box and papers.
