What To Do With Dust Inside Lens

One of the most frequently asked questions that I get from our readers, is what to do with dust inside a lens and whether it is something to worry about. I decided to write an article on this subject, because lens dust and flecks are a very common issue not only for camera sensors, but also for lenses. When I first discovered dust inside my brand new lens that I only used for a couple of days, I was very disappointed and I remember how I started searching for a solution online in panic mode. If you are frustrated with a similar issue and do not know what to do, keep on reading.

1) How to Inspect Lens for Dust

So, how can you find out if you have dust inside your lens? Actually, let me rephrase this question – how can you find out how much dust you have inside your lens? Because even brand new lenses normally do have some foreign particles in between lens elements. A quick visual inspection of the lens front will often reveal large dust particles behind the first lens element, if there are any. Just make sure that the front is thoroughly cleaned beforehand and any protective filters are removed. Look straight and then inspect the lens at an angle and you might see some dust behind the front glass element. Now if you really want to see dust, and I promise you will, here is the best way to do it. First, find a very bright LED flashlight. You can find those pretty much anywhere nowadays, even in a grocery store. Next, you will need to open up the lens aperture (the lens obviously needs to be dismounted from the camera, rear lens cap should be removed). If you have an older lens with an aperture ring, you just need to set the aperture ring to the smallest value (which is the largest aperture) like f/1.4 or f/2.8 and you are ready to go. If you have a modern lens like Nikon “G” type AF-S lenses, then you will need to push up a small metal lever to open the lens aperture as seen below. To keep the lens aperture open, you will need to keep pushing it with one finger:

Nikon G Lens Aperture Open

Once the lens aperture is fully open, turn on the flashlight and point it towards the rear of the lens with the front lens cap off. Do this in a dim indoor environment with lights turned off. Look at the front element of the lens at an angle and see how much dust you have inside the lens. If you have never seen any dust, you will certainly see it now. Better yet, now you can see dust in between pretty much every lens element, because it will be visible when a bright source of light goes through the lens. Now here is a word of warning – as I have pointed before, don’t be surprised to see dust even if you have just bought your lens. Some of those particles might be dust, others might be small bubbles and other glass imperfections. Why? You guessed it right, no lens is perfect! But don’t panic, every lens I own has dust in it, even the brand new Nikon 35mm f/1.4G prime that I have recently received from B&H. Take a look at how much dust my Nikon 24-70mm f/2.8G accumulated over the years of abuse:

Nikon 24-70mm f/2.8 Dust

And here is how the Nikon 50mm f/1.4G looks:

Nikon 50mm f/1.4 Dust

Looks scary, doesn’t it? But I don’t really care, because both lenses produce excellent results and I am sure will continue to do so for many more years.

2) How and Why Lenses Get Dust

You might be wondering how and why lenses get dust inside. Let me explain a couple of things about lenses. Every time a lens focuses or it is zoomed in and out, it “breathes”. And no, I am not talking about the effect of lens “breathing”, when an image appears smaller or bigger when focus is adjusted – I am talking about the process of inhaling and exhaling. Lenses have to breathe, due to lens elements constantly moving inside them when focus is adjusted and/or when zooming takes place. Remember what happens with pressure inside a closed plastic container? If you try to reduce the container size, the pressure inside the container will only let you reduce it to a certain level before it pushes back. A simple concept of air pressure in physics. Now take the same concept and apply it to lenses. What would happen if lenses were completely sealed from all sides? You would only be able to zoom in a little before the lens would force you back to its original state due to pressure, especially on lenses that extend in size. A similar thing would happen with lens focus. Hence, there was no other way for camera manufacturers to design lenses – lenses with moving lens elements must inhale and exhale air. Some lenses are better than others in managing the air flow. While some expensive lenses are sealed against dust (which does not fully stop dust from entering the lens) and will only suck the air in and out of the camera chamber, cheaper consumer zoom lenses are the worst in this regard – they might suck the outside air and blow it out right into the camera chamber. Let’s take a look at which lenses are worse than others in handling dust.

3) Lenses Prone to Dust

As I have explained above, some lenses are more prone to dust than others. Here is the list of lens types that are more prone to dust than others, in the order of “worst to best”:

  1. Consumer zoom lenses with extending barrels – examples: Nikon 18-55mm f/3.5-5.6G VR DX, Canon 18-55mm f/3.5-5.6 IS. Most cheap plastic consumer lenses have no weather sealing of any kind, including rubber gaskets that wrap around the camera mount. In very dusty environments, they will suck the outside air into the lens and then into the camera chamber.
  2. Professional zoom lenses with extending barrels – examples: Nikon 24-120mm f/4 VR, Canon 24-105mm f/4L IS. Cheaper pro-level lenses with Red (Canon) and Gold (Nikon) rings often have similar weather protection as expensive pro-level zooms, but are generally more prone to dust due to significant changes in lens barrel length. Most come with rubber gaskets on the lens mount to prevent dust from entering the camera chamber through the lens mount.
  3. Expensive/top-of-the-line professional zoom lenses with extending barrels – examples: Nikon 24-70mm f/2.8G, Canon 24-70mm f/2.8L. Top-of-the-line professional zoom lenses typically have better weather sealing all around the lens. Rubber gaskets are always included and other rubber seals are present in other parts of the lens such as zoom ring, focus ring, switches, etc.
  4. Professional zoom lenses with fixed barrels – examples: Nikon 70-200mm f/2.8G VR II, Canon 70-200mm f/2.8L IS. Lenses that do not change in barrel size are generally better against dust and moisture. Since nothing moves, there are fewer places where dust can accumulate and then make into the lens. Rubber gaskets and other rubber seals are also present in all areas where dust can potentially enter the lens.
  5. Prime lenses with extending front element – examples: Nikon 50mm f/1.4D, Canon 50mm f/1.4 USM. Prime lenses are generally less prone to dust than zoom lenses, because fewer parts move inside them. Prime lenses with moving front element that changes in length as you focus are generally better than zoom lenses, but dust can still make it into the lens through the front. Rubber gasket on the mount is sometimes absent (especially on older models), which can also contribute to dust making it into the camera chamber and the lens.
  6. Prime lenses with fixed barrels – examples: Nikon 35mm f/1.8G, Nikon 24mm f/1.4G, Canon 24mm f/1.4L II. Prime lenses with non-extending barrels are typically protected best against dust. Some of the prime lenses with rear focus feature (such as Nikon 24mm f/1.4G and Nikon 35mm f/1.4G) might have a moving rear lens element as you focus, while others have a fixed glass element that never moves. The latter is typically better than the former. Many of the modern prime models are designed with rubber gaskets around the lens mount and high-end models have additional weather sealing in other parts of the lens.

As you can see, prime lenses are generally better protected against dust than zoom lenses. However, there are exceptions, where some primes are worse than some of the zooms in terms of handling dust and moisture.

4) What to do with lens dust

Once you spot lens dust, what should you do with it? The answer is – nothing. Don’t worry about it and just keep on shooting, concentrating on creating great images. As I have explained above, lens dust is a normal fact of life, just like dust on your camera sensor. Even if you take a good care of your gear on a daily basis, you will eventually end up with dust in your lenses and cameras, guaranteed. You can certainly minimize the amount of dust getting into your gear by storing it properly and performing regular cleaning and maintenance (which I will cover in an upcoming video tutorial), but you cannot fully prevent it from happening. Dust is inevitable and it does get into camera gear one way or another, so you should not be sweating over it if you have it. Try an experiment – come close to a dirty window in your house and look outside. When your eyes focus on the outside, can you see the dust or dirt on your window with your eyes? No, unless the dirt particles are huge. The same thing happens inside the lens, if there are small dust particles, it is not a big deal. So take a deep breath, chillax and stop worrying about dust.

The only case where you might need to call your lens manufacturer, is if you spot an abnormally large spec of dust more than several millimeters in size that moves when you rotate the lens. There are cases, when particles break off inside lenses, typically after lenses are dropped/damaged.

If you are a very brave soul, you can try removing dust from your lenses by doing something like this. However, there is a high risk of potential damage, so do it at your own risk!

5) How to remove lens dust

Never, under any circumstances try to remove dust from inside lenses yourself. Disassembling your lens will not only void the warranty, but I can almost guarantee that you will not be able to assemble it back the way it was yourself. If large amounts of dust are heavily affecting your images and you have a very low level of contrast, call the lens manufacturer and find out if they can clean the lens interior and how much it will cost. Your normal lens warranty will NOT include disassembling the lens and cleaning its interior, so you will have to pay a hefty sum for that kind of service. In many cases, you are better off buying a new lens than trying to get an old one fixed. So, once again, never attempt to do this yourself and certainly never let a non-professional attempt to do it for you.

6) Minimizing dust and fungus

Shooting in relatively clean environments, properly storing your gear in a cool, dry place and taking care of it by performing regular cleanup and maintenance is a good way to eliminate fungus and minimize the amount of dust that ends up on and in your gear.

    Recently I found a dust speck under the front lens element of my Sigma prime lens. Hell knows how it got in there. I’m sure that it will not affect the image quality but it’s really disturbing my obsessive-compulsive brain =)

    Another “never ever clean this yourself” topic is the mirror.

      Muzaffar, I have a piece of hair in one of my lenses and I wonder how it got there myself :) Don’t worry about it! I know it is annoying, but things like that will happen, no matter what brand lens you use…

      As for cleaning the mirror – I clean mine all the time with a soft brush and I have not had any problems with it. Never try to wet-clean the mirror for sure :)

      I take mostly pet photos and recently got a small hair right in the middle of the inside of my front element of my 18-200. This “breathing” affect gave me an idea. Since it probably got sucked in through the “piston effect”, I could probably fix it the same way. I took the front lens off the camera, removing the front cap and rear body cap off and rapidly zoomed the lens in and out. Although it didn’t remove the hair completely, it did manage to move it to the edge.

        Good point Peter, It is unfortunate that I did not read this artical 1st. For the last 6 yrs I have been frustrated when a spot would show up on an award winning photo and even with editing I could still see it. I felt it was a lack of care that lead me to the imperfections. So, being and engineer I saw the problem inside the lens and figured the visible screw were there for a reason. Just like changing the lifters in my 1st car at 16, when I began taking things off strange noises of something was dropping into places I was not going to go. I got the lens apart found I was not going to get into the area where the dust was and I have not got it back together yet. I will not quit! No matter how much time it takes. But, to your point, DON’T ATTEMPT TO CLEAN IT OUT!!!

    I have no idea what this streak is on my pictures could you give me an idea? I bought a new lens, because there was a small scratch on my old one. However, the same streak appears in the exact same place. It is a line about 1 inch on the top right of my pics. Usually seen when shooting skylines, clouds. etc.

    What do you do when there are particles stuck on an interior optical element (perhaps second closest toward the rear of a micro lens)? These particles appear blurred out or largely absent at 5.6 or larger apertures. However, they become very prominent at f/11-22 and smaller. Because I shoot macro, I need as much DOF as possible (f/16-32). Mild softness due to diffraction is tolerable with a good macro lens, but these particles really ruin the shots. Removing the spots in Lightroom can be cumbersome, reference dust-off images even more cumbersome.

    Thanks for your pro advice!

    Thanks for posting this great article and it is enlightening to hear that everyone (people who are particular about the small stuffs:o) faces and got bothered by the dust thingy inside the lens and fustrated when you cant do anything with it. Even if we go servicing the lens and get it clean, the fungus can be gone but new dust will still comes through. So the near perfect lens condition with only happen in vaccum condition but that is provided you never going to use that camera. You are right, understand the fact and just get over it and focus on the shooting:)

    Dear Mr. Mansurov,

    I currently own a Nikon D5100 with its kit lens, and I am planning to upgrade to a D600 body and a higher quality Nikon lens. In addition to the usual family photos, I mostly like to shoot landscape in different environments, interiors (museums, historical buildings), and occasionally macro subjects. I haven’t decided about the lens yet, but after reading many online resources, and especially your reviews, it seemed that the Nikon 24-120 f/4 would be the best option in terms of versatility and image quality. However, things changed a bit when I read you article:

    http://photographylife.com/what-to-do-with-dust-inside-lens

    My understanding had always been that dust could only get inside DSLRs during a lens change. Thus, if you never change lenses, you will never get dust, so I thought, and that is why I preferred mid-range, all-purpose zooms. But to my surprise and dismay, now I can see that dust can get inside the lens during normal use, sucked in through gaps in barrels and rings. And to make things even worse, the lens, notably zooms, can also blow the sucked-in dust onto the mirror and sensor. Your revealing article provides excellent guidance and reassuring words about this dust issue, yet I am still a bit worried, so I would like to make you these few questions:

    1) With regard to sealing against in-lens and in-camera dust:
    1.1) Is the Nikon 24-70 f/2.8 significantly better than the 24-120 f/4 ?
    1.2) How about the new 24-85mm f/3.5-4.5G VR ? Is it significantly less protected than the 24-120 f/4 ?

    2) Does Nikon provide technical data about the sealing of their lenses ? For example, does Nikon inform about which and where sealings are applied ?

    Congratulations for your extremely useful website!

    Thanks for this great article. I was getting a bit worried about dust in my lenses. The issue being, I fly my cameras using a radio-controlled octocopter and, when taking off in a dusty environment, I get a lot of wash from the propellers that blows dust around. As a result there is fine dust inside my 18-55 lens already. It doesn’t seem to affect the photos though. I was starting to panic a bit but your article is very reassuring! :)
    As I don’t adjust focus or zoom during flight, I made a little sleeve from lint free cloth to surround the outside of the lens in flight.

    Good advice thanks.
    I have a Lumix DMC-FS35 second camera and found that suddenly some pics had a fuzzy mark which turned out to be a large dust speck inside lens.
    As all cameras are now digital and therefore solid state so to speak, I thought a firm thump in the palm of my hand might at least move the blighter.
    So after several thumps it moved out of sight !.
    There is also the thought that as dust is prone to static, maybe passing a magnet or magnetic material past the lens might do the same thing.

    Does anyone know if static electricity can cause dust to move around in a lens? I’ve got a lens that I thoroughly inspected and it was immaculate, and out on it’s first job, I had to swap lenses in an apartment that had thick carpeting, and a lot of upholstered furniture. This lens is a AF-S Nikkor-Zoom 80-200mm F2.8 ED-IF The dust is more like a flake, larger than most dust particles and it’s standing on it’s edge, inside the front element. I know it’s not likely to effect anything, but it is very annoying.

    I’m wondering if the static electricity from the thick carpeting could have moved the piece from the side, to near center of the front element. If this is the cause, how can I deal with static electricity in customers houses? I appreciate any advice at all.

    The Nikon 18-55mm is a starter lens, and as such, they always cost the least of All camera maker’s lenses. It most probably wouldn’t even be worth the cost of cleaning it. If it is still under warrantee and the dust is clearly inside, they may just replace it for you. I assume that you would remember adding the additional insurance, but since many dealers depend on it for profit, it is a possibility.
    This goes for your 55-200mm as well. They are worth a few percent more if they are VR lenses, But since these were just Kit Lenses to get you started, it’s time to start building a collection of quality optics, be careful though, of the “sticker shock” because lenses can add up real fast. You can easily spend $500.00 on a decent Prime lens, like a 35mm or 50mm F1.4 You can, of course turn it into an expensive “Point & Shoot” with an 18-200mm, or a 28-250mm, but be aware that this is not much better than the kit lenses. It is much better to choose your optics carefully, as they are the real expense. You will find that bodies come and go, but lenses can last a lifetime. That is one reason that most of us pick high quality, whether Third Party or OEM, the prices are not much different.

    I do have this problem too, but in my case it is affecting my pictures, here’s an example: http://i1295.photobucket.com/albums/b633/alejv98/Mobile%20Uploads/IMG_8772_zpsb51ded4a.jpg

    Hi! I recently bought a second hand Nikon 85mm 1.4D. Om happy with the lens, but I have discovered a quite amount of very fine dust inside the rear element. I haven’t noticed it on the pictures, but I find that the lens has low contrast compared thith my 50mm 1.4G. I noticed this after a portraiture shoot when I was shooting “the same picture” with both lenses. They look very different, the 85mm seems to over exposure slightly and has less contrast than the 50mm. Any ideas?
