This lens is now sold. Thanks for the interest shown.
Purchased this lens new from Vistek about 4 years ago. Complete with original packaging and metal case. This lens requires little description as it is one of Canon's finest. It was used in my home on a tripod overlooking a beautiful and active view and saw no outdoor use. It is in mint condition and absolutely no marks of any kind.
I will include a Wimberley Sidekick tripod mount with lens plate.
I have a flawless record on eBay (rgoodlad) for your reference. The serial number is: #35477. $5900 + shipping Paypal accepted.
