在canonrumor看到一篇最新有關24-70 F2.8L IS的rumor 這是連結
轉貼原文如下: The Good News
I have received a fair number of emails from various places around the globe about an upgrade to the 24-70 f/2.8L.
Two known sources say the lens is for sure in development.
The biggest word of such a lens come from Denmark. According to an email, someone at Canon DK let slip that the lens wouldn’t be in stock anymore due to an upgrade. The same sort of information was apparently passed onto a CPS member in Germany as well.
The Grain of Salt
It’s rare (but does happen) that a Canon Rep would ever know of a coming product announcement. Let alone spill the beans about it.
Another report said there’s issues in production with the new 24-70, and that’s why it has yet to see the light of day. The issue is in the new coating(s) for the lens elements.
I don’t post everything I get about the 24-70 IS, just because I have heard about an upgrade for years now. There has been a lot of tidbits coming in recently however.
