I'm still very much on the fence about purchasing the Vacuum Leak VPS-100.... Can I get some feedback from those that own it or own the Vivid Sentinel????
I agree with others that I'm hesitant to use a vacuum check system that requires me to unscrew and remove it AFTER checking the seal and possibly compromising the seal... Please advise.
My thoughts FWIW...
I think the tester is more about checking the integrity of the lens port seal and somewhat the rear main seal. If those hold then all you're really risking is not reinstalling the plug on the test hole properly. Once diving the internal electronic moisture detector will let you know if there's a problem.
I thought about getting the tester but I have no plans on swapping ports (I do mainly wide angle work) so I haven't shelled out the money yet.
