reluctantly selling my sigma 600mm contemporary lens . mint condition. glass immaculate. no dust . no haze . no fungus. only used in the dry. always had camouflage cover on. I have put my postcode in invisible ink in a couple of places. unnoticeable unless under ultraviolet light . just a security thing . can't be seen anyway with cover on. not heavy at all. doesn't sag when extended. autofocus very fast. beautiful lens . the sigma dock comes with this . very easy to use . lots of tutorials on you tube. my honest opinion of this lens is fantastic in all ranges. also boxed and has its own soft protective box. Thanks.
