HUGE but a huge help

I bought this product after finding multiple spots on my photos.



The best way to test if you have dust on your camera's sensor is to set your f-value very high such as f-22 and take picture of the sky or a bright piece of paper. Dust usually only appears in your photos at smaller apertures. You should be able to see most blotches clearly if you do the test right.



Anyway this thing did the job perfectly. I know how sensitive camera sensors are and am a little hesitant about using the "wet" method. And besides this is much cheaper. All you do is go into a dust free room (bathroom worked for me) take off your lens set your camera to mirror lock-up mode stick the little red tube into the lens bay and give it a few blows. Wait about 5 seconds after each blow to allow the dust to fall out. Just make sure you do this is a room free of moisture. Then you just pop the lens back on and take another test shot.



It also works great for taking dust off your lenses off of your camera out of your computer keyboard or really anything.



The only cons I can think of are that it is too big to fit in my camera bag and that it is loud. But it is still well worth the money and five stars.More detail ...

Works fine ... but you don't have to pay that much

If you haven't used a lens pen I think you'll be pleasantly surprised -- it works well. The description doesn't make it very clear that this product has TWO different cleaning tools one at each end. The brush which retracts is to take off dust particles. Hidden in the other end is a soft pad with a cleaning agent to remove fingerprints and more serious dirt hopefully without damaging the anti-reflection coating on your lens.



My only reservation is that this particular "Cleaning System" is a bit overpriced (at the time I wrote this review Amazon was selling it for about $21). Essentially identical double-ended Lens Pens without the Nikon name attached cost $8-$10 from many sources including Amazon (search "Lens Pen") so you're paying quite a lot to impress your friends ;-)



One more thought: another reviewer mentioned cleaning his lens daily with this product. That's not such a great idea. Camera lenses and especially their anti-reflection coatings are quite fragile. The more often you clean your lens the more likely you'll damage the coating or even scratch the lens due to a small dirt particle on the cleaning pad (likewise NEVER clean a lens with bathroom tissues since they contain tiny hard wood chips).



The fact is a moderate amount of dust and dirt on your lens does NOT affect the pictures you take since anything that close to the lens is so out of focus.



PS -- Here's an update: I just got an Adorama Camera catalog that lists this lens pen WITH the Nikon name for $6.50! Imagine that.More detail ...
