i have just been ripped off by someone on ebay.
i just bought a vivitar 100-300mm lens, but there is a small cobweb and a dead spider in the end of the lens.
when its on the camera (OM10 olympus) it isnt visible...but im not sure whether it will affect my photos.
i am new to photography also.
is it possible to open up a lens and remove the afore mentioned items?
any info will help me, thanks.
im in the U.K also |

They can be taken apart. But, you have to have some spcial tools. These tools will cost more than you probally paid for the vivitar lens. |

You can have considerable amounts of 'crap' inside a lens and still get acceptable results. Take a few frames under differing light conditions, ie also take a few into the light/sun and not just behind you. Use both the maximum and smallest aperture and both ends of the zoom range. A brick wall approx 4/5 foot high makes a good test 'card', by taking from both sides you can alter the position of the sun with reference to the lens.If the results look OK, just use the lens as it is.
It is relatively simple to make the required tools if you are mechanically minded. However if you have to purchase same, as stated above, they can be a bit expensive. Also zoom lenses are not the best candidate for a 'first attempt' at a stripdown. As you are new to photography, I guess the money would be better spent on film or useful kit. |

I am sorry to hear that you got done in by E-bay but i'm not surprised, they are getting worse. When you say in the end of the lense, is it in the front element or the element near the camera body? If there is two notches or slots in the lense where the spider is yu may be aable to fix it. Now if the spider is really separation in the element forget it and do what I would have done, ask for a refund and complain to ebay..I was scammed and will never go back to them...Don |

amazing where spiders can get. personally i dont recommend opening up lenses, purely because often they don't like going back together, but if you're confident then go for it. Glen said it tho, if it don't show up on the prints, then dont worry about it.
but do you mean the spider is on the front element, as in under the UV filter (if there is one), or at the back where the lense conects to the body? |

From http://www.certo6.com/services.html
"I got a Rolleiflex f1.4/50mm Planar once that had a loose spiral spring, some odd hardened liquid bubbles, dust, and a unidentified German insect in the lens … more nasty stuff that the average lens you would agree. I took the lens to Dresden (Germany) and used it, just to see how it would perform."
