It's difficult to fix a cage without completely rebuilding it as the cage goes around the camera. With the battery grip, the cage would have to be increased in height to fit the grip. I've found one company who makes a cage for $150. I don't know how it would be to handhold the camera with a cage and my curiosity hasn't reached $150 yet.Thanks for this. I get annoyed because for some reason with Firefox CR posts get relegated to Spam, so I'm just now finding this. I tell the system it's not spam but it keeps happening to me.
Anyway I'm always looking for feedback in this regard. One thing about accessories like an L bracket, sometimes someone with good mechanical aptitude can identify some modification that will correct the issue and I'm wondering if that's possible in your case.
As far as CR posts being marked as spam, have you tried taking the email address of the CR post and creating a contact in the FireFox address book? I don't use FireFox but typically if the entry is in your contact list, the email program will accept it. Also, if you point to the email in your spam folder and right-click on it, do you have any options to mark it as not spam?
