• A simple lens-cleaning system
• Small, pen-style design easily fits in any camera bag
• Soft brush retracts into pen body to stay clean
• Removes fingerprints, dust, and other debris that may compromise your image
• Works with all types of cameras (digital and film), as well as binoculars, telescopes, and other optical products

Your binocular or telescope uses highly precise optics. It's important to keep them as clean as possible to assure the best performance. Nikon makes it really easy and simple with the Lens Pen Cleaning System.

Beware the word "SYSTEM" in the product title. It is not a "system". It is a quick and effective means of removing many smudges and lint from viewfinders, mirrors, and some lenses. It is not a one stop shop tool to clean your expensive glass.

* the tiny tip is great for point and shoot viewfinder glass: it gets in the corners
* brush stays lint free
* i use it to clean the mirror of my DSLRs with great effect
* TIP: buy some cheap-o canned Air Duster (Memorex 3 8oz. can pack costs ~$15 and lasts for months with half a dozen cameras) and carefully blow off your glass and internals (hold camera upside down) do remove dust
* avoid any kind of wipes, microfiber cloths, chemicals (except "Invisible Glass Professional") for your optical glass investments. When using Invisible Glass always use a brand new (not washed and reused) microfibre chamois guaranteed to be lint and particle free. Don't do this often, and always make sure you blast off the glass with Air Duster to remove the hard particles first.

Otherwise this pen is a great little tool for small jobs. Just use common sense and don't ruin your glass.

It sa good product and did help clean properly my nikon d40x lenses and some other portable cameras lenses. good product

This is a simple thing to add in your gear bag. it cleans your lens fast and well with no danger of damaging your expensive glass.

While a simple glasses cleaning cloth would do for cleaning your lens but i would not use them because the Nikon Cleaning pen is DESIGNED to clean lenses and when you spent over $1000 for those expensive glass, i'd have second thoughts about using other alternatives.

this is an amazing product! cleaning optical glass was a pain until this item came along. eyeglasses, camera lenses, binoculars, spotting scopes, etc. are much easier to maintain now. i've been using one for about a year, and it is far and away the easiest and most effective solution currently available for removing fingerprints from optical glass. it truly works! while anyone could conceivably get a defective item, if you have trouble using the Lens Pen, visit their website and view the instructional video.

This pen has a problem with losing its hair. Had to seen my camera end to get the hair from the pin cleaned.
