My Nikon D3100 with a 70-300 lens has started leaving a lighter strip across zoom pictures. Looks like this. Attached File Attached File It's not doing it on the lower settings. Attached File Attached File Any ideas why? |

Is the lens fully mounted correctly? Do you have a second lens to try out? Is it the aperture change that causes the stripe or the focal length change? Try aperture prior ity at both far and near to narrow it down. I have a Sigma lens that works fine so long as it's forced to f/1.4 and works great, outside that the camera malfunctions and gives a lens error. Might be a sensor issue which pushes it to warranty/repair problem on the body. Bummer if not a lens issue and not in warranty. |

I bought the camera off eBay, so I don't have a great deal tied up in it. I'll try the other lens and see if the problem follows. Will a 20+ year old camera be worth repairing vs replacing if it is a sensor issue? |

Work up an exposure bracket* at different focal lengths. Same exposure using the range of f/stops and shutter speeds. Use a tripod, timer or remote shutter release, same subject for all shots-like the ones with the image issue. This will show wheee the problem comes from. I was going to guess shutter issues. But with out testing IDK. |

If you've already got lenses and it's not a lens problem (but kind of acting like it is), then I'd suggest a new setup. $900 for either Nikon or Rebel beginner DSLRs (Canon Rebel, Nikon 7500) would be a much more viable option than sending camera in for repair. The lens going for repair might be a different price (dependent on manufacturer), depending on aperture as a fast long lens can be worth upper 4 digits or more. |

Lots of things to take pictures of to figure out more. Varied focal length, fixed aperture from small to wide open, different lens, different shutter speeds, then see which mix can reliably re-create the problem OP is seeing. If it's intermittent and shows up now and again on all photos, no matter the lens or aperture, then your idea might be on the money and it's new camera time. |
