Dust, dust & more dust
So what's the best plan of action to rid my macro lens (and other lenses) of dust? In order to achieve greater DOF with my macro I use a tripod, set my F-stop high, my shutter speed long and my ISO low. When doing this many dust particles (too many!) make themselves known. Very aggravating. Also, how do you keep them dust free!?!
I'm so embarrassed to show this but here's the specs I see no matter how I try to keep my lens clean:
Shutter: 3.2
F-stop: 32
ISO: 200
BTW that's a milk carton handle.

Marleymax -- just curious, are you sure this is your lens and not your camera? I have a lot of dust, but since it appears in the same place with different lenses, I know it's my camera, not my lenses. Drives me crazy too.
Whenever I switch lenses, I use my Nikon lens cleaning pen (good for Canons too) and a chamois on both the front and the back of the lens.

Marleymax, that's on your CMOS sensor, not in the lens.

I'm going to go with the others and say it's dust on the sensor.

Superd I've been using the chamois cloth front and back but haven't tried a pen yet. I assume it uses a static charge to attract the particles? Are you having much success with it?
Tuftteach thnx but that's what I'm trying to avoid.
Red if its on the senor how do I fix it? I took my camera to a photographer friend recently and he used an air compressor blast on it. Worked well for a few weeks but here they are again. I can't afford my own compressor and don't want to keep bothering him with this. Does this pen help? Is there something else to do as well? I'll need to dbl check all of my lenses to see if these keep reappearing in the same locations.

You don't have to buy an air compressor, you can buy air in a can, it's much cheaper. But be careful! You can actually break your camera if you do it the wrong way. Read up on how it's done, or better yet- go by a used camera store. They will know how to do it, since they handle used cameras that often need cleaning. Some places will charge you, some will do it for free...
There should also be a sensor cleaning option in your camera menu (don't know what you have). What it does as far as I know is it makes the sensor vibrate gently so that any dust falls off. This isn't always enough but it should be the first thing you try. Only thing is you need to connect your camera to a power source or have a fully charged battery, because if it stops in the middle of the procedure, there could be trouble.

Duh to me! Compressed air cans! Why didn't I remember this? Sometimes I really wonder about myself! Thnx all.

Marleymax...I also have the Nikon pen cleaner, but I wouldn't use it anywhere inside the camera. I think it's just to clean lenses or filters.
As Superd said, if you get the same spots with different lenses, the dust may be inside the camera. The D80 manual mentions that if there is dust on the low pass filter in front of the CCD sensor, "it will show up as well-defined black spots when you are using a small aperture" (which you are).
Nikon recommends that you have the sensor cleaned by an authorized service center, but if that's not practical, the manual has detailed instructions on what to do. Some steps involving a "mirror lock-up" may be specific to the Nikon D80, but these suggestions probably apply to any make. Always hold the camera face down when changing lenses; use only a rubber bulb blower (while the camera is face down), to gently "puff" air towards the filter; don't use a brush, a cloth, or a compressed air canister, as they can damage the surface. Vacuum the inside of your camera bag (I'd never have thought of that without your question). The manual mentions that there are sensor cleaning materials available, but you do so at your own risk. You must be sure that you are working with a fully charged battery during the cleaning process.
It's not that I've had any personal experience, other than cleaning the lenses...your question had me pulling out the Magic Lantern D80 Manual. So far, I haven't noticed any spots, but I am thinking about a trip to the Sahara, so maybe I need to invest in a Giotto blower!

I agree with Red and RollsUp, this is most likely dust on your sensor.
Dust on your lens will not show up this defined and sharp on your image.
DO NOT USE COMPRESSED OR CANNED AIR to clean you sensor. It can introduce more dust into your camera body. It can blow your mirror and focusing screen out of alignment. It can blow grease used to lubricate you mirror all over your sensor.
Get your sensor cleaned professionally because if something goes bad it's their responsiblity. Remember to repair a damaged sensor costs can almost as much as a camera. Canon Professional Network doesn't charge much and they send the camera back in about 2 days.
If you're going to do it yourself, this site helps http://www.cleaningdigitalcameras.com/methods.html
The easiest way to avoid getting dust into your camera is never mount and dismount the lens in a dusty environmnet. And when you do, clean the outside of the body and always have the sensor pointed towards the ground.

You can get a bulb blower at any camera store... if you can find one. The hardest part of the death of camera stores is getting advice and the little accessories.

I recently bought one of those Rocket Blasters (the hardcore shutterbugs in the office swear by them.) Just wanted to let you know that the holes in the "fins" are, according to the packaging, there so you may attach the handy optional neck strap.
So, not only will you have a dust-free camera, you can be oh-so-fashionable as well.
I now return you to slightly less snarky commentary...

Rocket Blasters move the dust around and don't really eliminate it. Most dust on the sensor is either stuck on by static or by moisture, which the blower will not remove.
They do make pretty good toys.

Well, I had some dust in there a while ago and gave it a couple squeezes with the rubber blower. It hasn't shown up since, so if it moved it around it moved it somewhere very obscure.

All very good info. I won't be blasting my cam with compressed air – thanks Richard. Great link too. I'll try what Rodia suggests with the sensor cleaning option but think with this amount of flecks it won't do much good. (But keeping my fingers X'd.) From there I'll try some of the other suggestions here and keep you posted on my progress. Karol I don't wear jewelry so the rocket necklace is out – fashionable or not – sorry. BTW I use a Canon Rebel XT. Its old and already asked Santa for a new digi SLR. She just laughed. Yes, Santa is a girl in our family. My wife as a matter of fact.

Oh come on Mark, I can macrame you up a manly jute (or hemp - in he-shades of beige or black) strap with some macho shark teeth for added manly decoration. It could be a great entree into the man-jewelry world for you!
You could then let Santa know you are forced to wear it in public until you receive a new digi with built in sensor cleaning.
(Thinking like this may just be why I'm not married.)

Um -- can you do one of those for me so I can be forced to wear one until my Santa gets me a new DSLR?
