You need to be very careful because lenses have an antireflective coating on them that can be damaged if the correct claeners are not used, you should take this to a camera shop if possible, If not you can disemble if youself but i will need to know more about this camera.

Spot inside lens


NO!!! Don't even try because you can damage the mechanism. I would go to the Nikon USA website and go to the Service and Support tab. Nikon can give you a repair estimate.

Lens shacking automatically


I have a D200 with a Nikkor AF-S DX 18-200mm ED zoom, and I have a similar issue with the inside of the lens shaking when I turn it on, It turned out to be a problem with the vibration reduction motor inside the lens. I first noticed a problem when zooming that it wasn't smooth, as though the inside lens was catching on something. It turned out that a roller inside the zoom somehow caught the wiring strip inside the lens and damaged it, causing the VR motor to short out.
There are forums that tell you how to repair the problem yourself on that lens, providing that you can get the replacement parts. I elected to send mine in for a repair, and hopefully its going to cost less than $AU200.00

Cleaning dust deep inside a 18-200mm vr


Unless you have a lens collimator and other gear needed to reassemble the lens, don't even think about taking it apart yourself. If gentle shaking and tapping doesn't dislodge it, take the lens to a reputable camera shop and have a trained professional clean it.

How can I clean out the inside of my lense?


dont worry about dust too much unless it actually affects your image sensor.check it by pointing to a white wall or sky with f put to it maximum like 32/22 , focus and take pictures.. if its problem with the lens then it will make prominent dark speckles on the image.. but if you get dark speckles even at lower f - stops like 1.4/3.5/5.6 then its dust in the sensor.

dont try cleaning your sensor yourself as you may spoil it and finally have to refer a service center of the brand .

How to solve a very stif focus handling


Extend lens fully.
Look into rear of lens (sitting face down on your desk - no, lens, not you).
Use a good light or flashlight - nice LED one.

Note the two sets of helicoid threads, one inside the other.

With 5-25 cc syringe and blunt needle,
1 put a few drops of isopropyl alcohol at spots all around 360 degrees of each helicoid. Dissolves and rinses out old gunked up lube. Use q-tips to absorb excess when you rotate focus to spread isopropyl.
2 When focus is moving freely, apply few drops of lube - again all around the helicoids (both).
Now the work begins - rotate many times if sticking too tight. You will begin to feel it loosen and old lube will be absorbed by q-tips you run around edges of helicoids. You may have to apply, rotate 10 times, wipe with q-tip.

What kind o lube to use ? I used "Krytox", a common vacuum pump oil with viscosity of, say, olive oil. Also, you can use silicone dissolved in alcohol. Oil choice affects torque.

Isopropyl is your friend !

Spot on front element of Kiron 80-200mm f/4.5 zoom.


Kiron lenses had some unusual designs- doesn't have a thread ring holding the lens element in does it? As I remeber you had to almost completely disassemble the lens to get at that front element. FYI, the closer the spot is to the "optical center" of the lens, the less likely it is to have much effect on picture quality, EXCEPT if you shoot lots of bright objects, so you might just live with it

I have a SANYO VPC-T1060 i accidentally dropped it and it turned off with the camera lense out , i tried to turn it on but it wont


Usually when a digital camera has lens issues, they will turn on very briefly, then turn off. Try holding the bottom button in on the lcd side as you push the power button to see if your camera will display stored pictures. My daughter dropped her boyfriends 1060 in muddy water the other day and I cleaned it enough to get it to show pictures but couldn't get the lens to work. A drop or a speck of dirt will stop the lens from working. Haven't had much luck getting lens unstuck, but have replaced the lens unit, usually better to buy new camera unless you are very handy and can find a 1060 with a good lens and bad LCD, which I have done a few times. Looking on Ebay, most of the 1060's being sold 'as is' have bad lens and good LCD's......not good for us....hope this helps.
