My 200-600 lens has been great since I purchased it in 2018. I have had the screws back out slightly a couple of times, and I have used a jeweler's screwdriver to tighten them. Has anyone else had the problem, and how have you addressed the issue? Thanks.
There are 3 strengths of Loctite the medium one might be more durable than nail polish, and still allow the screws to be removed IF neccessary
According to Loctite's web [age "Medium-strength applications are those that require disassembly with standard hand tools without heat "
Are you aware of JIS? Japanese Industrial Standard.
Those screws that look like Phillips are actually JIS.
A JIS driver will allow the screw to be tightened to a higher torque.
