Thanks for the link. I saw this many years ago but did not book mark it. This chart is so helpful when looking to buy used lens.

Figured this is kinda relavent to the topic, a new 400mm 2.8 just announced. I admit I didnt' see that one comming. I see all the pro lenses getting updated with the same light weight process over time.
