i mean .. come on .. how big is the sensor, really .. a postage stamp? ... I just stick my finger in there and rub it around .. "voila" .. no more dust
I thought it sounded like a great idea but it could be viewed as just one more thing to get wrong. Still, pretty cool tech all the same. I was aware Olympus had a similar system but this one is supposed to be better. Also, I have a soft spot for Canon.
well i havent seen the auto dust removal software in action but if its any good id fail to see how doing somethin manually is more economical than an auto function but I guess the key words there were 'if its any good'
" i forgot which thread it's on, but i believe &Trisbert said the Olympus cameras do it better and have done it longer... " -- I think that was me?
Yep, Olympus' system is much better from initial tests I read and they've had it for four years. My E-500 never needs its sensor cleaned, ever, and I change lenses like a madman.
I have an Olympus E-300, and I didn't even realize that CCD dust was a problem. I have never seen a piece of dust on my sensor show up on or affect an image of mine. I also have the lens quick-change problem.
I don't know if this is pertinent to this discussion ... but .. apparently CANON advertises FREE sensor cleaning (I don't know) ...here are a couple rebuttals
i just use a giottos rocket air for routine cleaning these days and if things are really bad which is rare I turn to a VisibleDust Arctic Butterfly - both of which work really well.
indeed - I decided to get one after I enquired with Canons service centre in London about sensor cleaning and the guy on the service desk actually told me to buy one of the Arctic Butterfly cleaners and save myself a packet.
I also have an E-300 and even though it has a built-in sensor cleaning system, i managed to get the CCD dirty. Found a place near where i live (very reliable according to a couple of professional photographer that i know) and they charge $65 for the cleaning, although it would take a couple of days. I don't think i would venture into trying to clean it by myself. $65 is a whole lot cheaper than $800.
"It is not necessary to clean or change the dust collection components under normal use for several years. The dust collection system can easily deal with the particles that are a result of the dust reduction system. If the camera is used constantly in sever conditions, we would recommend that the camera body be sent to our repair service centers approximately at an interval of 3-5 years. As part of our camera service maintenance, the dust collection components are replaced."
"What is the origin and meaning of the supersonic wave filter? Where does the dust go?
The filter is named because it shakes the dust off of the CCD by using supersonic wave vibrations. The dropped dust off is deposited and affixed to a dust collection component under the filter."
The only thing i can think of is one day (no, not at band camp), kind of windy and probably was not careful enough while changing lenses. There a bit of new constructions going up in our area and it got kind of dusty.
This is from the Olympus Website : Located between the shutter and the image sensor, our exclusive Supersonic Wave FilterTM – a sort of “digital duster” – uses a high-speed vibration that shakes dust and other particles that might settle on the image sensor, causing them to fall away.
The vibration is unnoticeable to the user and occurs at a rate of 35,000 times per second. This vibration automatically takes place each time the camera is powered up, and can also be manually initiated through the camera’s menu. As these particles descend from the image sensor, they are conveniently caught by an adhesive material where they remain out of harm’s way. In doing so, you can capture vivid, dust-free pictures with every press of the shutter button.
