It is important to clean a Canon lens regularly and carefully. Camera lenses gather dust whether they are in use or stored. Dust, moisture, and fingerprint smudges not only affect the quality of images taken with dirty lenses, they can also permanently damage lens coatings if left to 'ripen'. Professional photographers know better than to simply wipe lenses with their sleeves. Carelessly cleaning lenses can leave permanent scratches, damage lens elements, and cost a small fortune in repairs and replacements. Therefore, owners of Canon cameras should know the proper way to clean their lenses.
Preparing the Canon Lens for Cleaning
Before cleaning a Canon lens, the owner must make sure to turn off the camera. If the camera uses an interchangeable lens system, then the lens should come off its mount. Once separated from the camera body, the lens is ready for cleaning. However, if there is a UV filter protecting the front element of the lens, then the owner should unscrew the filter first. Photographers who rarely take off their lens filters may find the filters difficult to remove. In such cases, a cloth can provide the tight grip required to separate the stuck filter. In addition, owners must take off the protective sheaths of their weather-sealed lenses before cleaning them.
Blowing on the Canon Lens
Dust is easy to remove from the surface of a Canon lens by simply blowing over the lens. A blower brush is required to do this. This is a small lens brush with a squeezable air bladder at the end. Before blasting dirt off the surface of the lens with a blower brush, the owner should squeeze it a few times to remove the dust gather on the bristles of the brush.
The photographer should place the blower brush over the surface of the lens and squeeze it repeatedly to remove loose dust on the lens. This is done for the front and rear elements of the lens. To clean a zoom lens, the owner should extend it to its widest focal length in order to access the total surface of the lens. In addition, photographers should avoid using pressurized, canned air as the aerosolising agent can dirty the lens.
Breathing on the Lens
Unlike dust, smudges and fingerprints are tougher to remove. To get rid of residue, the owner should first breathe on the surface of the lens in order to dampen the front and rear elements. Then, the owner wipes the lens with a folded piece of soft micro-fibre cloth. The right way to wipe down the lens surface is to work the cloth gently in a circular motion from the edge to the centre in a lifting rather than rubbing action.
Cleaning with Lens Cleaning Solution
Simply blowing on the lens may not remove greasy stains. For difficult stains, a lens cleaning solution is required. The owner must not apply the lens cleaning solution directly to the lens surface; just as wiping the lens without first moistening, it is wrong. Therefore, the owner must first wet a lens tissue or soft micro-fibre cloth with the lens cleaning fluid and then wipe the lens surface with the moistened cloth.
Some photography experts recommend isopropyl alcohol in place of methanol as a lens cleaning solution because it is milder. However, it has higher water content and, therefore, does not evaporate as quickly as methanol. Generally, lens owners should avoid cleaning their lenses with household cleaning products. When in doubt, they should use the lens cleaning solution recommended by the lens manufacturer.
