Hi all I'm getting back into my photography after about 10 years and now I'm in a better financial position have treated myself to a Canon 750D and a Sigma 150-600mm telephoto lens. I've never owned a lens like this before and am just after advice on how to now carry and support my camera and lens. The lens weighs in at 2.8kg. Am I right in thinking that if I'm carrying my camera around with the lens attached I should be doing so by using the strap attached to the lens and not around my neck attached to the camera? Any other tips on carrying it would also be appreciated! Will be using mainly for wildlife photography, so lots of walking. Thanks!
