Perhaps there is no general rule for your question. Fresh lens pen made by Nikon should last about a year, if immediately capped after usage. It also depends how often you use it. The moistured end dries out quicky if left open.

Also depends where you live, e. There are some 3rd party lens pens, sometimes of unknown origin, that may not last that long, or may be already too dry upon first usage. Post Reply. Just wondering how long a lens pen should last? I have had one for about 2 months now and seems as though its not working to well anymore, left a smudge last time I used it.

I'd say 2 months sounds about right. I go threw them about that often, but then again I'm obsessed with any little speck that gets on my lenses. Breathe a little bit on the lens before cleaning. It'll polish it up just fine. I guess it really depends on the amount of cleaning done with it what kind of dirt and how many times.

If the "refresh" turning the cap doesn't help anymore, you need a new one. Style Selector. All times are GMT The time now is AM. See also: NikonForums. It's great to see you back on the forum!

Who ever invented such a POS!?! One week I buy a lenspen 'cos everyone is raving about it on here, and the next week it's the biggest POS ever invented. I just can't keep up. Welcome to a web discussion group Opinions are like, um, something else everyone has. How true last summer I met a Photogragher who works for the Seattle paper and he let me play with his Canon camera.

Boy was I shocked to see the condition of his camera, it was filthy but can he take great pictures. I took lens paper, cleaners, cloths, and everything else recommended with me. I also stuck a lenspen in my bag on my last trip. After managing a big old thumb print on my lens, I tried all the stuff to clean it, but to no avail, admittedly because I probably didn't know what I was doing.

Till then, it's lenspen for me. My perspective comes from both my passion for birding as well as from my job as a research biologist using ridiculously expensive microscopes.
