[Jim Betz via Tweeters]

Hi,

   If there is someone on the list who feels competent to give advise on 
Canon

equipment for birding photography (not video) please contact me directly/off

list.        jim betz at jim betz dot com               - Thanks ... Jim

P.S. I currently have an R7 with the RF 100-400 and a 1.4 converter.  Am 
considering

        a wide range of new gear that may or may not include the RF 
100-500, the

        the RF 200-800, the R5-II, a tripod with a gimbal head, etc.
