You commented, more than once, that you were not sure of something you were videoing because you couldn't see it properly. Once may have alluded to the low angle of view vis-a-vis the activities on top of the platform, but I got the impression that you couldn't see the screen/viewfinder properly. Anyway, I can understand and appreciate the difficulty of toting a camera + long telephoto lens a long distance. Some photographers have a hip sling to slide the lens into but then there will be undue strain on your hip joint because you will walk funny. A neck strap just put downward pressure on the neck and results in nuchal strain. Cradling the camera in your hand while the telephoto lens is tucked under your arm often results in accidentally hitting the shutter button. Cradling both the camera and the lens like an infant feels comfortable at first but will eventually cause a backache. You need a crew of young people with muscles that call you boss.
