What if my camera has an integrated sensor cleaning function?

Most digital SLR integrated sensor cleaning systems use a vibration technique to remove the dust from the sensor. However, this function simply shakes the dust off the sensor and does not remove it from the digital camera chamber. Since the sensor is electronically charged, the static build up will attract the dust back on to the sensor during continued use. Although vibration can be a useful and helpful preventative technique, it cannot remove other types of contaminants that may be adhered to the sensor surface such as organic materials and internal contaminants like camera lubricant. Only the SensorScope cleaning system addresses all four types of contaminants and offers a safe and effective solution to remove each type.

Why doesn’t the SensorScope System include a blower?

Your camera’s manual may recommend using a blower to clean your digital SLR sensor. However, blowers displace dust and debris inside of the sensor chamber without removing it. Dust returns to the image sensor once your camera is in use again. Blowers also increase the chance of introducing other foreign debris and moisture with force.

What is a sensor?

A sensor serves the same function in a digital camera that fi lm does in an analog camera, which is to capture a visual image. When you click the shutter button, the camera quickly switches the mirror out of the way, and then the image is directed through a low pass fi lter before it reaches the camera sensor. The mirror is connected to the shutter imer system, so it stays open as long as the shutter is open. This is why the viewfi nder is suddenly blacked out when you take a picture.

How does a sensor get dirty?

Contaminants can enter your digital SLR camera in various forms and in many different ways, but they all affect the quality of your photographs. Some contaminants come from internal man made sources within the camera such as chamber lubricant and manufacturing dust that become shaken out, and others from external sources in the environment such as pollen, small fi bers from clothing, dew and organic dust.

How does this affect my photographs?

When contaminants are present on the low pass fi lter that sits in between the sensor and mirror, the sensor pixels are blocked from receiving that portion of the image and show up as artifacts or dark spots and lines on your photographs. Depending on the size of the debris, these artifacts can be barely noticeable or can potentially ruin your image.

How do I keep my sensor clean?

Every time you change your lens you are exposing your sensor to external contaminants. Because your sensor is an electronically controlled component of the camera, it becomes magnetically charged during normal operation. This magnetic charge literally draws both internal and external debris onto the sensor and fi lter surface and holds it there until it is manually removed. Many times the debris becomes chemically bonded onto the sensor or fi lter surface.

Always use a lens mount cap when the lens is removed to prevent dust from entering the camera. It is recommended that you change your camera lens indoors. However, there are many times when you need to change your lens outside. Make sure you change your lens quickly and protect the camera as much as possible from dust and other contaminants.

Refer to your camera’s manual for recommended techniques on changing lenses.
