Hi

I was hoping for some quick advice before I go and do something irreversibly stupid. My d200 with AFS Nikkor 18-200mm lens attached was dropped ( thrown) while in a lowepro bag and the attached UV filter has shattered. The lens cap took the brunt of the fall and has pushed against the filter. There's a lot of very small shards and powdered glass on the front of my lens. The main problem is that there are many pieces of glass jammed into the filter thread on the end of the lens. What's the best way to shift them without damaging anything? Any quick tips?

And would anyone like to adopt a 4 year old boy?

Thnaks in advance for your help
Tom
 
Use an air duster can to blow the shattered glass powder out?

Air duster or a mini vaccum first. I'd favor the vaccum to avoide blowing little shards into anything.

As for your son -- just charge it to his allowance.

it happened to me something similar with the 17-35 f2.8.
I could not even unscrew the filter as i bent the outer edge of the filter.

To be honest i brought it to Fixation in London (authorized Nikon assistance) and they unscrewed the filter and cleaned up everything. The lens was as new, nothing happened to it, luckily, but i did not dare to touch it myself.

cheers

Second...I would use a Giotto Rocket Blower and I would be extremely careful about amount of blowing pressure and direction of blowing. Thirdly...I think a good quality fine/soft lens brush would be next....Save the pressurized can blowing for last... if at all...We know dust bunnies can get inside lenses....so tiny bits of glass could also...or worse...could scratch the lens glass....
 
Get the glass out with air blasts then remove the filter with a small strap wrench they make for stuck filters which you probably have.
 
I know that you may be feeling that there may be little scratches that may affect the picture or somehow, your lens isn't the same.

Don't worry too much as any scratches on the front element are not as great as an impact as any on the rear element. I know because I had a 28-70AFS and D1X mash down into sand (I can't go fast in deep sand - imagine that). I don't typically use filters for protection and I did have the lens hood on.

Holding the lens up to the light, you can see many fine scratches on the front element all going in the same direction. However, this lens is still one of my sharpest lenses although I understand that there could be some contrast loss in certain situations.

Don't feel too bad about the 4 year old as I'm sure that he/she would be worth more than your camera and lens combo and if it were a situation where you would have to choose between the camera and your child, you'd pick the child.

Hope this helps.

From lots of service experience, NEVER blow out. Too much change of moving particles into a crack or opening. Also a change in the case of a lens in blowing particles against the glass lens surface.

Home Depot carries kits to adapt from a standard vacuum hose fitting down to small tubes and brushes. They are usually in the aisle with the Shop Vacs. Using them, you are able to get more effective suction due to the increased air velocity.

I bought similar at Radio Shack a while back - Dirt Devil Detailer. About the size of a large banana. Comes with a couple of small brushes. Perfect for periodic cleaning of lenses and body crevices.

Sorry to hear it got damaged but be carefull cleaning. I had the same thing with my old 80-200 f/2.8. The filter broke and glass got into the lens and when using the auto focus you could hear the glass crunch and crack,...not a nice sound. Sent it to Nikon for internal cleaning. THey ahd to disassemble the lens, clean it and align all the elements again. It came back AS NEW, but it cost more than a couple of hundred bucks...

Good luck,
Drew
