Hi, I recently bought a used EF 400mm f4 DO lens, and it came with a Jobu lens plate. I want to replace this lens plate with my Wimberley one. The problems is that the hex bolt is over-torqued and stripped. I don't want to risk damaging the lens collar by drilling or excessive force. Any suggestions on getting it off? Thanks. Cliff

I'm travelling to east of Madagascar (Masoala, Andasibe, Berenty) in near future and wondering how about security when taking photo gear with me (backpack, tripod etc.). I have read about robberies in this country, especially in the cities, in the night and on main roads between cities in the southern part of the country. Does anyone have (recently) experience with Madagascar? How big is the risk of beeing attacked? And how to avoid / minimize risks?
