->> Canon 16-35 EF Lens, Comes apart--- see attached photo
Has anyone had this happen to their 16-35mm lens I was covering the Caribbean World Series had used the lens and when I went to use it again it came apart on me, if it has happened how much do you think Canon will charge to repair it. See Hidden gallery Canon 16-35mm in my member page. |

| ->> No, I've never seen that happen. Looks repairable to me, but who knows? |

| ->> Had that happen with a cheapo 50/1.8 II after I dropped it on a gym floor. Has it suffered an impact recently? |

->> I had my 70-200 come apart in two pieces a few years ago. Aperture failed and as I was taking the lens off the body the barrel came apart. After 4+ years of just about daily use the screws had loosened enough that the whole thing just came apart.
If I remember correctly no parts were replaced in the repair. Just needed to have the assemblies put back together and the screws put back in and tightened. |

->> I've stocked all my bags with micro screwdrivers just to keep my lenses from falling apart. The front end of 70-200 comes loose every few weeks. My 16-35 has an internal loose screw. My 400/2.8 mount keeps coming loose. There are 10 Canon users on my staff almost all of them have loose screw problems. We had to put gaffers tape over the hood screws on the big glass so we wouldn't lose them when the come out.
I transport all my gear in Think Tank rollers too. It's not like they're rolling around in my trunk.
They should send a spy to Nikon to see how they tighten screws. They could learn something. |

->> One piece of advice that I want to pass along. DON'T use Locktite or any other glue on the threads of those tiny screws. Those little tiny Phillip's points won't handle the torque needed to break the glue's bond and will instead strip out. Sooner or later everything needs fixing and when that bench tech strips those screw heads not knowing that the screws are glued in you'll jack the repair bill that much higher.
Instead a dab of clear (or you can express yourself with a color) nail polish on the screw head and surrounding metal/composite will hold the screw AND can be removed to service the lens with a dab of acetone. |

->> Thomas -
Sorry to hear you work with 10 staffers that have "screws loose" :) I've got a couple of loose screws myself...... |

| ->> I check the small screws on all of my lenses once a week. The Canon 70-200 f2.8 IS regularly needs some tightening, the 16-35 less so and the 24-70 hardly ever. |

| ->> Eric - So does Nikon use red Loctite just to give themselves a hard time? |

->> Don't know maybe someone should drop them an email and ask about using Locktite on loose screws. I just know what has been told to me first hand. We've all been told lots of do's and don'ts only to see a factory tech do the exact opposite.
Case in point EVERYONE knows not to use 'canned air' when cleaning a sensor..... except the last NPS clean and greet that I went to both bench techs were blasting the sensors with cans of 'canned air' as part of a normal cleaning.
Maybe the screws that Nikon uses Locktite on are harder, or noted on the service sheet so that the techs are aware. I really don't know. Just going on what a bench tech told me.
I'll bet you this.... Let them find a screw glued that wasn't glued at the factory and I'm willing to bet that anything additional that it takes to fix the lens will be on the bill. Warranty be damned. |

->> On the topic of 16-35's coming apart, does anyone know the part number for the 3 tiny silver screws than can be found under the rubber focusing ring? If you peel back the ring and rotate you can see them.
My focusing ring jammed up, when I peeled it back to take a look a small screw fell out. It's gone for good. |

->> Serafin-
This happened to my Canon 16-35 EF lens and I took it to our equipment manager. He was able to recover the screws that had come loose and, fortunately, had just fallen into the lens barrel. Once he re-aligned the screw holes with the internal element mount under the front rubber ring the lens was fine.

| ->> Serafin, this happened to my 16-35mm lens too. In addition to a loose barrel, was also having trouble with the focus because one of the screws had fallen into the focusing ring mechanism. I sent it to Canon and also had them calibrate and clean & check. I think I paid $180 or so, but my memory is foggy. I'm a gold CPS member so that saved me 30% off the cost of the repair. |
