Went for a three hour walk with my 5d3, new 70-200 f2.8 IS mk2 attached to a new BR7 curve and my Border Terrier, Watson in tow. Love the BR method of carrying this combo, one hand on the lens for peace of mind most of the time, do not feel the weight compared to the neckstrap ( I have the lens pointed forward, but it often wants to sit to the rear after taking shots, then I adjust it, what would most recommend lens or body in front?) my only concern is on getting back to the car I noticed the lockstar had become open! so this is another weak link! I will be paranoid about using this strap until I implement the safety methods mentioned by others in this post.
