Hi everyone, I have had the Canon 100-400 for 2-3 years and I have been very challenged with the connection to my Canon 7D Mark 11. The connection will frequently fail when I pull up the camera to photo BIF, stills on monopod, good weather and bad weather. I have cloth-cleaned the connections on the lens and on the camera and air cleaned them after. It doesn't happen with my 24-70mm Canon L lens. The only way to get the camera to work again is to turn it off and back on and start over with my focus, etc. Anyone else have these issues with this lens? If so, how did you fix it, please?

May I add that there may be someone you know who can assist you to help with setting up the formal photos. When I married 36 years ago, I had already had 2 years experience (not a lot, but just enough) working in a professional studio and when our best friend, an amazing hobby photographer, offered to do the photography, I discussed a list of photos desired, how to style them, and that I would be involved, etc., and he agreed with the plan. Then on the wedding day, I did a lot of the set ups to keep things moving so that we could do those before shots, during and after photos that met his creative needs and my "must have" needs. This gave him time to do his magic. Even today when I look at those beautiful photos, I am struck by the wonderfulness of his creative genius.
