Dust particles will eventually find their way onto the filter that rests in front of the DSLR camera sensor. Many camera models have their own dust removal systems but they are only affective to a certain degree. Sooner or later most DSLR owners will notice small dark spots on images which are more apparent against blue skies and when the aperture is closed down.
The thought of cleaning the delicate insides of a new expensive camera does send some people weak at the knees. Your options are to pay someone to clean the dust away or do it yourself. The DIY option makes sense financially as who knows how often you will need to clean it. Even those who rarely change lenses will get the dust issue as zoom lense will suck air in when you zoom the barrel. You will need to choose between a wet clean or a dry clean. The safest is of course the dry clean and at it's most simplest form there are small devices that blow clean air onto the sensor to blow the dust away. However this only moves the dust around in the camera. A better solution is to remove the dust particles using a brush. This review is about the Visible Dust 724 Super Bright which does exactly that. You can find it for £90 upwards from online retailers.
The brush comes in a protective padded box. It consists of 2 parts, the handle and the brush which has a clear cover to keep the brush clean. The handle is comfortable to hold and the plastic has a nice texture. On the side you have a switch which powers the brush on, off and also activates the 2 LED lights located at the front of the handle. Two small AAA batteries provide the power. The brush has fibres that are electrically charged and attract the dust particles when they come into contact.
Using the brush is easy but care must be taken to not touch the sides of the camera chamber when you insert the brush. The sides in the camera chamber will have lube and this will containment the fibres. Once you have put the camera in cleaning mode and removed the lens, you simply lie the camera on it's back. You then remove the cap from the brush and turn it on, the motor in the handle will spin the brush head at fast speed and this will cause the bristles to charge while also dislodging any dust on the fibres. The instructions advise you to spin the brush 3 times for 5 seconds each time. You then push the power button to turn the lights on and insert the brush into camera, then swipe the brush once over the sensor filter and then extract the brush and reinsert to swipe the sensor a second time using the other side of the brush. It is as simple as that. The 2 LEDS are useful as they allow you to see the internal of the camera chamber so that you avoid the fibres of the brush touching anything but the sensor filter.
The brush does a very good job of lifting dust. In 6 years it has performed flawlessly and is a quick easy way to keep the sensor dust free. There is a liquid cleaner available to keep the bristles clean and you can also buy a more heavy duty brush head.
