Canon 0573C002-cr EF 1635Mm F/2.8L III USM Lens, Black (Renewed)

So, if you don't know already - this is one of the best lenses Canon makes. It's really expensive - and if you are fortunate enough to get a refurbish or return that's been marked down a lot (like I did) then you should consider yourself really, really lucky. That kind of deal doesn't come around all that often. This lens is so popular that it's one, if not the most counterfeited lens by some garbage Chinese knock off companies in Yangon. So hopefully you get an actual real Canon lens.Mine works great - has all the stuff you'd expect and when I registered it on the Canon website - it was confirmed to be an actual Canon lens. Good luck.

Best on scale from good to better to best for wide angle lenses!
