Before you remove the lens element, consider this. Do you have a lens collimator and other equipment necessary to ensure proper alignment when you replace the element? If you don't, please leave lens disassembly/reassembly to a trained professional with the proper equipment.

DON'T TRY TO FIX THIS YOURSELF! You will only add to the damage. If your lens is in warranty, contact Nikon for instructions to get it repaired. If it is out of warranty, I would either pay Nikon for the repair or take it to a camera repair man.

SOURCE: Haze behind front lens of Canon FD 50mm Macro lens

If the built in lens hood has a rubber grip ring at its base, it is possible that the ring conceals access holes for grub screws that lock the ID ring in place. The ID ring is obviously the hood retainer as well as filter mount. Even if no rubber ring, the disassembly instructions may have you removing the whole front section so that hood goes rearwards - revealing grub screws. If the ID ring seems reluctant to move do not force it, Look for one or more lock screws.

if it is only fogged you can blow hot air on the lens while fully zoomed in and after the water has evaporated, zoom out to compress the moist air out. do this several times.

POSSIBLE MOLD INSIDE CAMERA LENS


It is lens fungus and you're correct in your assumption that it's uneconomical to professionally repair on your lenses. But it need to be pretty bad before it affects image quality so don't junk them just yet.

Some types of lens fungus can be killed simply by leaving the lens out in sunlight, but I'd suggest that it's better to leave them exposed to the indirect sunlight on a bright overcast day to prevent any chance of sharply focussed light burning the inside of the lens. Killing the fungus won't remove the dead stuff but it prevents the problem getting worse.

Dust inside lense


Removing internal dust normally requires a full internal cleaning, lubrication and adjustment (CLA). Internal dust, if it is not a lot, will not affect picture quality at all. On many camera lenses you can stick the small tube on a can of compressed air into the back of the lens and a few moderate blasts may remove some of the internal dust. Yet this is not recommended since it is quite possible to accidentally dislodge focus cam or zoom cam grease and blow that grease onto a lens element or (worse) onto the aperture blades. So, the point is that mild to moderate amounts of internal dust won't affect your photos.

AV error whn pentax ist DL & Quantaray zoom lens attached


I've got the same problem. The problem is that the lense is loosely attached to the body. What you need to do is that when you see the Av flashing, press the lense of the camera to the body and twist the lense to the left a bit. This tightens the connection. You can then take the photo.

Canon 50mm f3.5 Macro Lens// nFD version 1980 Haze behind first element


Haze is condensation. I am schooled in optics and physics. Seriously, if you go to a local pawn shop they will verify what I say. Mold in the lens optics will follow. I would gladly send you a lens if you are destitute but do not throw bad money (time) after good. Steve Medley

How to get the lens apart to clear bits on the front element


The front element is easy to remove.
There's a plastic cover on the front of the lens which has a very small hole in it.
Get something like a very small screwdriver in that hole and prize the cover off.
Remove the 3 screws in the next plastic cover and remove it.
The next 3 screws you see hold the front lens element on.
This whole part rotates to adjust the infinity focus and is kept in position by those 3 screws.
Make sure you mark the position by maybe making a small scratch in the plastic next to one of the screws.
Or maybe scratch around one of the screws.
With those 3 screws removed the front element with the lens just falls out.

I dropped my EOS Digital camera and 300 MM Zoom lense in the river. The camera has dried and seem to be workin gfine, but the zoom lense needs to be cleaned.


Dear catnip54,
You could obviously clean the front and back elements on the lens(use a microfiber lens cleaning cloth), but there is no way of cleaning the inside of a SLR zoom lens other than having an authorized service technician take it apart and clean each lens element seperately(which could be expensive). I would count myself very lucky that your camera body still works after being immersed in water.

Sincerely,
Agent Allan
Go Ahead. Use Us.
