I know it is not a rumors site, but I have never had someone tell me point blank what's up. I called Canon service about fixing one of my lenses the other day and mentioned that I was thinking of purchasing a 300mm f4 IS. He said that a new one is being announced in July and it will have a pretty good sized price hike, but should be super sharp like the other new glass out. Has anyone else had an issue where they would just offer up information like that??? I thought everything was usually hush hush about stuff like that.
