I just got this very simple but well designed wireless reciever mount for my F3. Using one of the threaded holes on the handle it allows for two ew100/500 recievers to be mounted almost flush with the handle. The camera now fits into my bag without removing them.
It's made by the mechanical shop at SVT (Swedish public tv) in Stockholm.
Can you post the address at SVT where I may try to have some made also.SvaraRadera
Thanks very much,
Give SVT a call at +4687840000 and ask for "verkstaden" where they make modifications and add-ons for cameras and other equipment.
