Help, Sensor Problem

->> In the middle of shooting a basketball game my images started to show a streak of light in them. I think my sensor might be going bad, am I right, or is it something else?

->> Jeff,
That looks like a blown shutter.

| ->> I think the same...the middle image was shot horizontal and the images left and right of the 3 vertical. Shutter blade sticking. |

| ->> That isn't what a blown shutter looks like in my Canon, but it's close enough to be the main culprit. What kind of camera? |

->> Phil- I'm under the impression that there are two types of "blown" shutters. One where the blade is flapping around causing a black band, and one where the blade is stuck to another blade, causing a gap.
In the first example its come loose on one side, so the faulty blade whips around causing areas where no light strikes the sensor.
In the latter, it's stuck on top/under another blade but both sides are still attached.
Just pop your lens off and look inside. It'll be pretty obvious. |

->> Reading about blown shutters got me thinking if my camera's shutter blew out.
I only own one camera body. What would be some pro-active steps I could take so I don't get caught during an assignment with a blown shutter? I keep track of my actuations for fun. Would having the body tuned up every so often help in knowing the condition of the shutter or is it a sudden and unpredictable thing? |

| ->> Jonathan. The only way to get around a blown shutter during an assignment is to have a back up body. |

->> Daniel: After I noticed the problem I saw the refs and ball just sitting them and took that shot, thought it look really cool.
Phil: I'm shooting on a Nikon D300.
Will: I was shooting with flashes, set up with pocket wizards. One of the first things I did was take a shot without the flashes and under exposed the images and that's how I got the middle of those two shots.
Jonathan: The best thing you can do is carry a second body with you. Sadly this was one of the few times I didn't have my backup camera with me.
Thomas: I popped of the lens and looked around on the inside, but didn't notice anything out of place. Could easily be a stuck blade and I'm just not sure what I'm looking for. |

| ->> Yeah, your shutter is gone. I've been through a few blown shutters. If you keep using the camera, it will eventually get even worse. Send it in for repair. Good luck. |

->> Jonathan,
Also, there's little help the actuation count will give you in terms of predicting the shutter being blown. It's such a rare event - the shutter of the D300 has an MTBF of 150,000 cycles - it would be sort of like saying, there hasn't been a perfect game thrown in MLB in so many years, there should be one today.
Preventive maintenance MIGHT help - I'm not a camera technician, but I assume a trained tech might be able to spot *some* conditions that would indicate a blown shutter is imminent - but even that would be a shot in the dark (pun intended).
A backup body doesn't have to be much - even something like a D70 or a D2H would be better than nothing.

->> Jeff, Blown shutter. As far as trying to predict when a shutter is going to blow.... good luck. I have a D2Xs that blew right around the MTBF a D200 that went at 34K and a D3 that lasted 600K. By the time you've paid to have the body stripped down to the point that the techs can see all of the parts of the shutter AND paid to have the camera put back together you may as well flip for the cost of the shutter itself.
As far as what the techs can 'see' it isn't much. The metal fatigue that causes the blades to sick or fail can't really be seen with the naked eye. My D3 that had the shutter replaced last month had the mirror begin to stick today. There's just no way to know when a part will fail. All ways carry backups |
