Mine came Friday. Many people ask what a Refurb lens is like, so I snapped some photos. Then, I took it out and used Focal to check and adjust AFMA.
My lens arrived looking like new. A careful inspection revealed tiny scratches on the electrical contacts showing that it had been mounted a few times. Otherwise, there wasn't a mark on it, and the hood was obviously new and unused. The glass was clean and perfect.
The AFMA resulted in a "0" at 70mm, and a "+2" at 200mm on my 5D MK III. It was a quick and dirty test, so it might be refined once I have more time. We did have a sunny afternoon, so there was plenty of light. In any event, it was basically right on, a +2 AFMA makes no visible difference.
Here are the photos showing how it is packed.
