Lenspen REAL TEST – A Tool For Optical Lens Cleaning Review
Lenspen is a very popular tool for cleaning optics. We made a real test of a pencil for cleaning lenses. So you have the opportunity to find out whether it is as good as the manufacturer says.
There are reviews and tests of Lenspen on a number of sites and Youtube channels. We bought such pencil and tested it. And it did not do what the manufacturer promised.
But let’s start from the beginning.
Lenspen is equipped with a brush that is comes out on the side. This brush is made for cleaning dust from the lens. This is a very important point. Never clean your lens from fingerprints if you had not removed dust from it using brush or Air Blower Cleaner. Even the smallest dust particles can scratch the top layer of the lens when you will clean it from fingerprints. We liked how Lenspen cleans lens from dust. For this, we put 5 out of 5 possible stars!
On the other side of Lenspen is an element for cleaning lens from fingerprints. This element is closed with cap. The manufacturer claims that in this cap there is special not wet mixture that allows better cleaning of the lens surface from fat. They say that every time you put on a cap, element for cleaning is replenished.
To test the cleaning of the fingerprints from the lens, we put one fingerprint on the lens and began to rub it in circular motions with special element (as recommended by the manufacturer). However, the fingerprint did not disappear; it just smeared all over the lens. We put on a pencil replenishment cap, scrolled it in there and tried to clean the lens again. The smeared fingerprint became smaller but did not disappear. Once again we repeated the procedure with replenishment cap. And we tried to clean the lens one more time. However, the lens still had traces of print. They were subtle, but still visible. So after use of Lenspen you still need to rub lens with a piece of microfiber. For cleaning traces of fingerprints we give Lenspen the rate of 2 stars out of 5 possible.
Average rating is: 3 stars out of 5 possible.
The question is whether to buy this thing? The decision is all yours. It failed to remove fingerprints, but successfully cleaned of lens from the dust.
We took the video of the entire test, where you can see how it happened:
P.S. On the Internet you can find a lot of positive feedbacks about Lenspen. We do not know with what it is connected. Perhaps the representatives of Lenspen paid for good feedbacks. Perhaps all these tests of Lenspen are advertising.
But there are another two options.
First – people did not realize that Lenspen cleans from the fingerprints insufficiently. Firstly, we conducted a test, at which we thought that Lenspen is good with lens cleaning. It really cleared lens from fingerprints. But a few minutes later we saw that the lens had visible stains. We did not notice it right away, because they were visible only under certain angles. Perhaps people who have used this tool for cleaning lenses examined the result not precisely enough?
The second option – perhaps we got Lenspen of poor quality. This may be Lenspen of some defective lot and all the rest clean the lenses really good?
Hi,
Lenspen has been around for over 20 years and not only them, but other major companies (Nikon, Canon, Hama, etc) have done extensive testing to really understand how well it cleans. For these years they have had these customers ordering product for a long time.
Your test shows only one pen, used only 1 time, on 1 lens, and experienced bad results. Out of the tens of millions of lenspens produces, it is highly likely you got;
a) a fake lenspen
b) a manufacturing defected lenspen
Your post is jumping to conclusions based on one piece of evidence, and is therefore invalid.
