I find myself in the need to bring this subject once again.

Some of you guys told me that in order to clean the lenses from dust and fingertips the lenspenwas a good choice.

But I've got a dilema right know. should I buy on the lenspen homepage or elsewhere? Where do you advice (online)?

And what kind of a blower do you advice also, and a sensor cleaner (just the though of it gives me headhache)?

I'm really thrusting in everyones help. HHEELLLLPPPP!!!

you can get microfibre lens cloths at most opticians. Make absolutely sure that you don't get an ordinary cloth as they will probably scratch your lens/

well, I get a lot of dust in my lenses. Specially in thetele (Nikkor 70-300 ED). Some say it's because of the zoom. The in and out of it causes lots of electrostactic and it atracts dust. The thruth is that every time I put the front cap on each lens if becoumes with dust spots on it and I have to clean it. I've got a cloth from a optic store but I think is the cheap version because it has allready scratched my glasses.

So I gess I'll need a blower to ger rid of the dust and a cloth or some tissues. But I've readed about lenspen and it seems very good.

Since I've started to use the tele I've noticed that in some photo's, at full zoom, especially when shooting birds in flight, I get some spots in the photos, always in the same location. In the first shooting session I thought it was because of the rain, that I did'n notice small water drops on the lens, but it happened again. Afterwards I cheked the back of the lens and I saw some dirt spots, that I'm not shure they are the responsible for the spots on the photos, or if it is dust in the sensor.

So I gess I'll have to do a total cleaning of all parts to make shure everything is ok, because next month I'm starting to shoot for money.

Here's an example. I've enhanced a lot the contrast so it can be well seen. this is a crop at 100% pixel crop. In the image there where at least 6 spots like this. anyone can tell if this is in the lens or dust in the sensor. i've never own a SLR equipment before so I can't tell.

could you take the same picture at f22or 32 or your highest stop , shoot the clear sky (keep it manual focus & shoot for infinity )
if resolves to a dark pinpoint or spot -- its on the sensor, if you see stong lines its likely clear crud onthe sensor
if it is fussy - it's the lens

i use pecpads & 100% alcohol method

as far as exterior cleaning (i had cow spit on my lens today -- eeeewe)
leftover sensor pecpads (mostly clean) & alcohol

Nuno, first of all I'd make sure if it is dust in the lens, or the sensor.
Take a photo of blue sky with a small aperture (like f22), then change to a different lens and take the same photo.

If the spots are in the same place, you'll know it's the sensor, not the lens.
