If it cannot wipe it away with gentle (virtually no pressure) swipes then DO NOT use more pressure. Gently (with virtually no pressure) see if the brush can wipe the dust away. the actualy sensor is a couple layers below the surface you can touch). it's really a glass filter in front of the sensor. ![]() This causes the reflex mirror to swing up and it opens the shutter curtain so you can access the "sensor" (again. Put the camera into "manual sensor cleaning" mode. This brush should be pristinely clean and free of oils (resist the temptation to feel the brush with your fingers and get skin oils all over them.) Give the brush a firm "whack" on the edge of a desk to knock loose any dust that might be clinging to the bristles. and then I use two more tools.Ī) You can use a sensor brush. I tend to grab a magnifying loupe to inspect the sensor to see what I'm working with. So don't go rushing into anything further without reading and following the cleaning instructions, watching instructional videos, etc.ģ) Sometimes a few puffs of air isn't enough. If you choose path (b) you'll need some proper cleaning supplies (more on that later) but the MAIN thing you have to realize is that you can damage things if you aren't careful. You can either (a) take the camera to a camera store that cleans sensors (they usually don't charge very much and it can be done quickly), or (b) decide to clean it yourself. If it isn't clean at this point, you have a decision to make. The Giottos "rocket" blower is a popular hand-squeezed blower. It usually doesn't take much air to clear the sensor. and it's not rapidly decompressing air that will fog the sensor by chilling it. If you use a hand-squeezed bulb, the puffs of air don't have any contaminants, no oils, no films, etc. So the probability is that if you use canned air or an air compressor you'll actually make things worse. The propellent leaves a "film" residue if the can is not held upright (and not shaken). The same is true of cans of compressed air. Both are very bad.Īs air rapidly decompresses from an air-compressor it will splatter moisture and air compressors are lubricated with oil and the "air" will put a residue on your filter. then use a HAND-SQUEEZED air blow (emphasis on HAND SQEEZED). Sometimes just a couple of sensor cleaning cycles is enough. The "problem" is every time you take a shot, the reflex mirror "wooshes" up and down and that blows the air around inside the camera so the dust can migrate. the dust can exit the camera (otherwise it's just going to settle somewhere else and it's just a matter of time before it's right back on the sensor again. This can often "shake" the dust off the camera.īut the reason for removing the lens and pointing the camera opening at the floor is so that when the filter does vibrate to shake the dust loose. But the front-most filter is attached to a piezoelectric charge device which causes the filter to vibrate quickly. There's also a "low pass" filter (reduces the moiré effect) that can show up when shooting certain patterns. These do things such as block IR and UV light. there's a couple layers of filters (glass) directly in front of the sensor. Technically the dust isn't on the camera "sensor" per se. You can also use the menu system on your camera and navigate to the menu item that lets you manual invoke a sensor cleaning cycle. ![]() Point the camera body at the floor and switch the camera off. To clear these, you can try a few tings.ġ) Indoors (no wind), remove the lens. ![]() At high focal ratios they'll be well-defined. The intensity of the dust spots will depend on the aperture setting used for the particular exposure.Īt low focal ratio values (f-stops) the dust spots will appear weaker. You CAN do this yourself if you buy the tools and read and watch videos on how, but you may prefer to pay a camera shop to do it. If you have stubborn dust or if there are water spots or stuck-on crud that you can't live with the sensor needs cleaned. Blow the heck out of the sensor and the inside of the camera in general with the camera facing the ground so the dust falls out. Make sure the battery has a decent charge so it will continue holding the mirror up during the procedure. Go into the MENU tabs and tell the camera to raise the mirror up to locked position. The thing you see when you take the lens off is not the sensor it is the mirror that the camera uses for focusing and to show you the world through the viewfinder. Look at YouTube videos for help and visuals. You can easily remove it from a blue sky using software, but not easily from those trees.ĭefinitely buy a bulb blower and use it.
