K&F Concept Lens Cleaning Pen, 3 PCS Two-in-One Function

Its convenience, portability, and effectiveness make it an essential tool in my photography kit. This pen combines three cleaning tools in one: a retractable brush for dust removal, a soft cleaning pad for fingerprints, and a carbon tip for stubborn smudges. The brush, pad, and carbon tip seem durable and can be used multiple times before needing replacement.

These pens are a great alternative to other lens cleaning products where there are 4 different options in one. There are 3 in the pack, which is perhaps not needed but I like knowing I can take one away on holiday with my camera and not worry if I lose it or break it.
One end of the pen holds a mini double ended cleaning pad- one has a circle shape and one a triangle shape which helps depending on what you are cleaning, especially getting into any corners (eg. the viewing port of camera). This little item slots into the end of the pen and a lid clicks on over it to keep it clean.
The other end of the pen has the brush. Half of the brush is already extended and can be used when you need it to be a bit more stiff, but then there’s a slider that moves the rest of the brush out so it’s longer and more flexible for dusting. There is a lid that clicks on over the brush to keep it clean. On the end of the lid is a suction cap for pulling off more resistant dust. My main niggle is that there is no lid/cap to go over the suction cap when not in use. I’m not likely to use that because I can’t prevent it getting dirty wherever it’s being stored or kept during transport. Additionally, the suction cap is slightly wider than the rest of the lid so if not kept in a suitable place, it’s likely to get bent/warped which will impact the suction ability. All this needs is a secondary lid to cover the suction cap.
All of the options seem to do their cleaning job well and I’d feel confident being out for a day with my camera with only this and maybe a couple of lens cleaning wipes.

On first seeing this product I noticed it’s made by K&F Concept. A company which makes good wallet friendly products beloved by youtubers. So I instantly knew this would be a good and I wasn’t downhearted when I got to play with it.

Especially as this is a 3 pack for just under 15 quid (at time of order). So I can afford to buy one pack and stick these in different kitbags and flightcases. That way I’ll always have a lens cleaner to hand.

What’s even better is these do a really good job. Simply pull of the rubber cap, extend the brush using the red button and (along with a puffer) you can remove loose dust in seconds. One nice touch here is the red button locks into position after being moved.

At the other end, protected by a hard plastic cap, is a very flexible dry cleaning pad. I’m not sure what material it’s made from, just that it doesn’t need any liquid. Mainly, even when the lens has a protective coating, I know each brush will do a grand job of cleaning fingerprints and smudges off lenses.

After I’m done getting dirt off the lenses, I can easily retract the brush and add the caps back on. Then I can use the side clip and store this in my jacket like a big pen. Which makes me happy and if I’m happy I take better photos.

And these work on more than cameras, they also work on binoculars, telescopes, mobile camera lens, action camera cases and even spectacles. They also do a good job on the rear screens of DSLR’s.
So if you need to clean your lenses, this one is well worth trying.

This is a review for the K&F Concept Lens Cleaning Pen.

I ordered this set for two specific purposes. Firstly to clean my camera and binocular lens and secondly for cleaning components inside my PC. With lens cleaning, I used the pens as the manufacturer describes and they did a good job. They proved particularly useful on a pair of compact binoculars which had previously resisted all attempts to be cleaned. With the PC, I only used the brush head, using it after using an air blower.

I think the design of the pens is clever. What would be ideal for working with the PC, would be built in LED light.

I hope you found this review useful.
If you have a question, I always try to respond when Amazon forwards them to me.

You get three of these in the box. Each pen has two capped ends, one cap protects the very useful little brush that pops out using the slider on the side. This replaces the soft clean tiny artist’s paintbrush I kept in a little pouch in my camera case for dust and hair. The other end has a little triangular cleaning pad designed to be used dry. On my Canon EF 100-400mm old trombone mk1 lens this appeared to make no difference. Perhaps the lens was already clean though. It did clean my phone camera lens well. These are well-made little cleaning pens that don’t take up a lot of room. The price isn’t bad. They are a handy size, and the brushes will get used. I’m not so sure about the pad for my camera lenses. For phone lenses and other smaller-sized ones they seem to be OK. For my camera lenses, I’d be inclined to stick with my specialist soft cloth and lens cleaner solution.

I got the K&F Concept Lens Cleaning Pen, 3 PCS Two-in-One Function with Cleaning Brushes & Carbon Tips, Suitable for Camera Lens and Filter Cleaning product from this page – a 3 pack of their entry level, plastic body, pen cleaning tool kit. There’s a one pack as well listed above when I write this.

This is the multi-tool you can carry in the UK and the police can’t really complain much. You’re getting a three pack of these and as far as I can see, they don’t sell replacement heads for their range of similar pens so it feels like these are considered disposable. That screams single use plastic and I’m not a fan of that really, especially as they sell a higher end aluminium pen with more attachments/heads. Why not just treat the pen like a screwdriver, get yourself a pen that stores and mounts heads, and sell replacement, recyclable heads? You’d think that would go down well with a lot of photographers who spend a lot of time in natural environments.

Anyway, this is a three pack so either you recognise that these cleaning tools are going to get dirty and you can’t clean the tool itself well enough to guarantee it won’t damage your lens, or you need enough to have one to hand in multiple spaces. If you’re cleaning a lens, the last thing you need is to transfer dirt back to it because the cleaning item itself is now dirty and greasy, or worse, scratch it, so disposability makes sense from that point of view. It’s also the type of thing you might want in multiple camera bags, to be sure you don’t go out without one.

It’s got several tools in this version – the 3 PCs Lens Cleaning Pen. There’s a suction sucker on a cap that conceals and protects the brush. I honestly do not know what that’s for, it feels like they ran out of ideas, put it there and their picture shows the pen hanging off a window. So… maybe it’s for precisely that so you can stand by windows, take photos, and quickly grab your pre-prepared cleaning pen while taking a lot of photos in a dirty environment next to a window? I couldn’t find an explanation in the description when I wrote this review, so yeah, maybe they should add one.

Anyway, as a cap that does protect the brush, which is also hidden inside the pen by the sliding switch. I really didn’t get that combination, because it makes no sense and they haven’t explained it in their description. There is no manual to explain it either.

What’s the point of hiding a brush with the weird suction cap/pen cap combo, and also retracting it? I could not for the life of me figure it out until I spoke to my father who has a similar one. He said, if you push the slider out a little way, the bristles are effectively shorter and therefore stiffer. Extend it fully and they’ve got more play. So that’s the explanation and kudos to him for figuring that out because they did not explain this themselves. To me, it just looked like a totally redundant mechanism that did nothing useful. If I were them, I would make that a selling point and at least describe it.

While they’re at it, they definitely need to justify the suction cup. Perhaps there’s a thing people use that for? Without a manual that explains why, how would anyone know? I don’t see a reason to stick it to a window. There may well be a reason for it to exist, and if so, it’s a selling point they’re not really using. Even if it’s just fun to stick things to smooth surfaces with suction cups when you’re that bored.

The brush is quite fat, flexible bristles which seem a good balance of stiffness and therefore can flick dust and specks off things and I see no reason why it should scratch anything. As above, it turns out you can control the length and stiffness so that may help with your dusting.

The other end has a pen cap style lid and a reversible insert with a circular carbon tipped pad on one end, and a triangular one on the other end. You just pull them out, and since it’s silicon it’s a friction fit.

There is a pen clip so you can clip it in a pocket if you want. Which is fine, not that I imagine many people using it.

I would prefer to see a more environmentally friendly version of this, with a tool body for life, and replaceable heads with relevant recycling instructions. As it happens in my area such stuff would get incinerated, which is better than nothing but in many places I suspect it ends up in landfill. But realistically since they have all these heads in their various products, like screwdriver bits, that’s how this should work. One range of heads, works in all their pen bodies, recyclable, available as spares. Heck, you can sell the cleaning case that holds pen, cloth, liquid, wipes, heads etc.

It’ll do the job you want it for, and other than the dubious recyclability it’s basically fine. Not a standout product but it should do the job. At the time of getting it, the three pack offered a big discount per pen over their single offering, which is good. It’d make a good stocking filler for a family who all have cameras I suppose.

I suggest they do the following. 1) explain what the sucker is for, and if you can’t ditch it, it has to have a function or it’s manufactured waste 2) sell attachments in packs so people can replace dirty ones 3) provide recycling information/encourage that 4) point out the mechanism lets you adjust brush stiffness because no review I could see mentions this and I feel like I’m not the only one who didn’t figure that out themselves, not all the customers will realise this is a deliberate feature 5) give some information about the heads – are they disposable when dirty, or can you clean them and should you, or do you not because at a certain point they become a risk to your lenses?

This is fine for the basic version though, and their other ones do offer a wider range of heads for cleaning stuff like earbuds which need different heads and probably get a lot more disgusting than lenses. If they do sell those separately, great but I couldn’t see it on their store page or this multi product page.
