EX-1 dust in lens at DVinfo.net

Dan Chung · November 3rd, 2008, 01:28 AM

I've discovered a large speck of dust slap bang in the middle of one of the inner elements of my EX-1's lens. I have no idea how it could have got there, I was under the impression that the EX-1 lens was well sealed to stop just this sort of thing. Has anyone else had similar issues? and if so did Sony clean it under warranty. Given all the issues with EX-1 focus and backfocus I'm a little nervous about how well callibrated the lens would be after disassembly and re-assembly.

I had specs inside the lens and so have some others. One guy even had a piece of fluff inside his his lens and unsealed the front lens and removed it himself. I sent mine in to sony and it came back fine. Is the spec silver in appearance? I suspect flakes of the sealant that is used to seal the front lens on sometimes flake off in the inside but that's just my theory.
