Good luck... 800mm is slightly sharper and faster than 300-800
hope you will find soon...
thanks, i also am always at the long end of zooms for birding and the 800mm saves 3 lbs V.S the 300-800 plus the focus and sharpness it's a no brainer for my purposes. not really common though which is the downside from purchase standpoint, more people have the 300-800.
