When it comes to cleaning SLR camera lenses, photographers use different methods that work for them. In this article, I will show you my way to clean DSLR camera lenses. I often get emails and comments from our readers, who ask to provide detailed information on this process, so I am including a detailed article along with an accompanying video to thoroughly explain the process. Cleaning lenses is a fairly straightforward process and is almost risk-free, as long as you are using proper tools for the job. If you are impatient and want to see the video where I show the entire process of cleaning a lens, skip all the way down. I hope you find the below article and video useful.
1) Why Clean Camera Lens?
Besides the obvious answer “because it is dirty”, keeping your lenses clean will ensure that you get the best and highest quality results from using your gear. During a Photo Walks that I led a couple of years ago, a novice approached me with a question about his camera. He told me that his images look cloudy and he had no idea why it was happening. I asked if I could take a look at his camera to see if I could find anything wrong with it. As soon as I opened the front lens cap, I knew exactly what the problem was. The front element of the lens was very dirty and had oily fingerprints and other stuff all over the place. I showed him the lens and asked if he knew about the problem. He told me that he had a toddler that likes his camera too much and apparently, that’s how the lens ended up getting all the stuff on it. He did not know how to clean the lens properly and after spending so much money on the camera gear, he was too scared to clean it himself. Gladly, I always carry my cleaning kit with me, so I took a picture before and then another after cleaning the lens. We compared the images and as expected, the first one indeed looked cloudy, while the second one was clear and sharp. This is one example of how dust, dirt and oil can affect your images.
Another important reason to clean your camera lens is keep your images free of particles that might show up in background highlights and other parts of the image. Take a look at my earlier post on “the effect of dust on lens bokeh” – you will see, that dust on the rear element of your lens will show up in your images, especially if you have large specks of dust there.
Dust is a normal part of a photographer’s life. While it is a good idea to prevent dust from landing on your gear, whether you like it or not, you will eventually end up in a dusty environment some day. So, it is not a matter of how, but when. If you see a beautiful sunset on a windy and dusty day, are you not going to take a picture? Some photographers say things like “do not get your gear dirty in first place”, which I consider to be a ridiculous statement. I would never want to miss an opportunity for a good picture, just because I wanted to keep my gear clean. Every time I go to places like Sand Dunes, I know beforehand that it is most likely going to be windy. Take a look at this shot:
