I really like the optical quality of new lens but I have to say on my copy the Tripod Mount - to ring attachment is pretty rubbish and when you examine it it looks like a cheap after thought.
After 1 week of using the lens on a monopod/tripod the 4 screws that retain the black plate that the Tripod Mount Foot screws into to had worked free, at first it was just a little bit of shake but after a further day it worked itself totally loose. I missed shots of Fraser eagle Owl posing nicely because I couldn't steady the camera (well annoyed).
As I didn't have a small phillips screwdriver with me, i had to tighten the screws as best I could with a pen knife but that would only hold for a half day session before it needed tightening again and after an hour on the canopy walkway at Kakum (very bouncy) but without even mounting the camera / lens it fell off (fortuately caught it with all the screws rather than had it fall 140M to the forest floor but paint also came off the mount foot.
I contacted Canon who want me to return the lens for repair but as it is Optically great, much better in my view than 100-400 Mark i or my copy of 400 I'm wary of sending it back and having to go back to my back-up for a while.
I could I suppose just glue the screws in and touch up the paint but I assume that would invalidate the lens warranty.
Has anyone else had problems with the Tripod Mount ?
If so what did you do?
