Of course you can say every manufacturer has a bad unit now and then but then again we have many many barcos with no lens issues either.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Apparently too many people were having a hard time seating the lens properly before engaging the locking mechanism so now they are advising to close the locking lever then slide the lens in until it "clicks" in.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 03-28-2018 05:23 PM                     that's not new in my knowledge, Sean, I was taught that many years ago. Still, I have seen myself mounts where the locking mechanism had gone loose and the lens itself would wobble if grabbed from the front and pushed around a little.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-29-2018 11:20 AM                     quote: Sean McKinnon You can say that Mark but we have other NEC installs without this issue. I wish I could claim some of my sites had that problem, then I could do some service calls!! Another hint: The 3200 and 3240 use an entirely different lens positioning system than the 1200 and 2000 use. Mark  |  IP: Logged
