Just doing a clean before I go out to WTP. Something I noticed the last time I was there was there was a fairbit of dust. I've been a slackass and not bought a UV filter but then again I didn't expect this to happen. Just taking a look down at the rear elements and the 2nd last one to where the lens mounts to the camera has dust on it. I've spotted about 8 particles of reasonable size. Has anybody else experienced this? I'm really disappointed for a lens that retails for $3200 to allow dust particles through the front element.

I haven't had this problem and I have to say I wouldn't expect this either - especially since the lens is internal focussing.

Yep, I wouldn't have either because I've heard rumours about the telescopic zooms how they can create a vacuum that sucks dust into the lens. I'm pretty positive it's dust though as I can see it on the rear element but when I go to wipe it off it remains. Then when you take a closer look you can actually see it's on the glass behind. I'll take a photo of it when I get home today and post it up.

anything coming up in your pics kipper at f/22?
my old 80-200 has heaps of dust in the front element can't be bothered sending it out for a clean, probaby would cost more to than what i paided for it.

does it show in photos Kipper?

Hi Darryl

Last week I went to the zoo with the 80-200 ED with some of dust visible when I look rear just can't clean because it is inside of the rear glass, but to my supprise, it does not show on final picture.

Haven't tried an F/22 shot of the sky yet. Might do today.

That what is the additional of UV filter for! It protects the dust and some unexpect thing happens to the front element, if you don't want to shoot with the UV filter then remove it and put it back in storage or transit.
I told you and mentioned in few posts previously but you would like to hear some other experts on this forum and did not want the filter, then if in case you need to send it away for cleaning, the damage is four to five times the cost of the UV filter itself.
I have the 70-200VR nearly 3 years and found no dust anywhere

Hi Kipper,

The dust particles will not affect the picture quality. Dust will still get in even if you have UV filter at the front. I don't think the dust went in by the front, rather by the zoom ring where the internal lens moved (if it IF).

Zooms are more affected by this problem than primes. Push pull is the worst of them all.

How are you storing your lens when you are not using them? Best to store all your equipment in an electric dry case.

I get new dust showing up in the camera's sensor even when i am not using them. I had it stored in my camera bag till my dry case arrive.

In summary, it is unavoidable. If your lens have dust from usage - it's good, it shows that you are putting your lens to good use rather than gathering mould in storage.

It is a pain but you can send it to Nikon for cleaning, calibration and VR check etc..

regards,

Arthur

UV or any kind of filter can minimize the dust and other unexpected stuff happens to the front glass.
Dust is the normal thing happens in our life, whether you're storing in a seal case or in a bag, just minimize the affecting of the dust get inside your equipments, we're breathing dust in our lung every breath, no matter what.

Birddog, it has nothing to do with me ignoring what the so called "experts" have had to say about using UV filters. The fact that I don't have a UV filter comes down to pure laziness on my behalf, nothing more. Last week I looked at buying a UV filter, than forgot about doing anything about it. So it has nothing to do with me thinking I know what is best. As I have been meaning to get a UV filter since I got the lens.

Arthur, I store the lens mostly in the Loewe Pro Compu Trecker that I have. I also sometimes store it in the lens case that it was shipped in. I don't have a dry electri bag or whatever they're called.

Hi Kipper,

IMHO, even you have UV filter, i doubt it will help preventing dust from getting into the rear elements. Maybe you should check how dust your camera bag is. The bag not the absence of the filter is the culprit.
