I have been using a Fuji 100-400 on my X-T2 to take pictures of my grandkids playing Lacrosse. Sometimes I have 4-6 games in a day to shoot at about 800 shots a game. I use a monopod to hold the lens, but now am concerned about the weight of my right arm on the camera body putting a torque on the camera to lens fitting. I tried a cable release last weekend with fair results. Am I being paranoid about causing a mechanical problem with just holding onto the camera with the weight of my right arm?
