Maintain Your Canon Digital SLR Squeaky Clean

Among all the digital SLRs that have flooded the market, canon digital SLR camera s the most trusted. The reason for this is that most models can be used by amateur photographers as well and the picture quality is unmatched by any other SLR in the segment. They are the best in what they do- that is give you great pictures with minimum effort. As with any electronic instrument, the key to their performance in in their maintenance.

Dust is the biggest threat to a camera , especially an SLR which inevitably has a bigger lens than a regular digital camera . The easiest way to prevent dust from messing up the camera is to keep it in its cover when it is not being used. Most camera s come with the dust cover or camera cover. These should be used.

The most important part of the camera is the lens. It is also the part that is most exposed to the outer environment. The lens should be covered with a lens cover when not in use. It is best to avoid touching the lens as the fingerprints will smudge the lens. Fingerprints can be wiped off easily in most cases but it is difficult to remove dust from the corners of the camera lens.

Sometimes, the picture quality might have gone gradually bad without you realizing it. In most cases, the reason is dust. To confirm if you have dust or smudges, click a picture of a uniformly colored wall or carpet or sky. Check the picture. If there are unexplained spots, you need to try cleaning the camera lens.

It is quite simple to get dust off a lens. Easiest is to wipe it off with a soft damp cloth. If that does not work, use compressed air to blow off the dirt off the surface of the l ens and other camera parts. Do not tilt the can or the compressed air will drop on the camera as liquid. That may harm the camera parts.

Mini vacuum blowers for keyboard cleaning can be used to blow dust off some parts of the camera that cannot be reached by any other means. If you are planning to use it on the lens, check the vacuum brush. If it is not soft, do not use on lens. It may scratch it beyond repair. And sometimes, the blowers just blow the dust around. So, use the suck option if there is one after blowing around the camera parts.

It is of utmost importance that you use recommended cleaning agents to clean the camera and its lens. Never ever use household cleaning liquids to clean a lens. It may damage the lens. Look for cleaning agents in stores or ask canon dealers. Always check with other digital SLR owners as most people are ready to share their experiences and mistakes online.

After cleaning the lens thoroughly, if you still find that you are getting smudgy pictures, there may be dust on the sensor. You have to be very careful while cleaning the sensor. If a sensor gets damaged, its repair may cost as much as the camera itself. It is best left to the professionals.

This telephoto zoom lens is designed with canon ’s Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on canon EOS camera s compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with canon ’s 4-stop stabilization correction, you could [Read More]
