There are tons of threads on this issue, here and on other sites. The bottom line is...if you have a DSLR you will eventually need to deal with dust/crap on the sensor. Actually, as I have stated before the dust does NOT reside on the sensor itself but, on the filter in front of the sensor. It is a myth that some "attract" more dust than others...and also still somewhat in dispute is the theory that the charge from the sensor is actually strong enough to hold dust. The reason dust shows up more on some camera images is primarily due to the distance between the filter (where the dust sits) and the sensor itself...the closer the two the more the dust will show up. Also, as Fstop moves up....dust becomes visible. Many ways to deal with it currently; 1) Live with it and clone out 2) Blower method 3) Static brushes 4) Wet wipe sensor 5) Send in for service With regard to a few issues raised here; 1) On the "vibration" clean DSLR cameras...a couple of things to consider...Will the sensor/filter assembly fully and most importantly ACCURATELY realign itself distance/orientation wise after every vibration cycle? Check other forums, there have been some problems. Do you want your sensitive electronic components to suffer an ultrasonic "shakedown" on every power up? 2) Sensor/filter dust can NOT be seen through the viewfinder....the mirror reflects what is seen through the lens into the viewfinder. If you see debris in the viewfinder it could be from debris on the lens, mirror or on the viewfinder screen itself. Sensor/filter dust will only show up on the image after the mirror lifts and the CCD/CMOS is exposed. 3) There are things worse than dust....shutter fluid...esp with new cams. If that happens to get on...go immediately to steps 4 or 5 above. 4) From my experience, your brand new out of the box DSLR will already come "prepackaged" with a few dust bunnies. @L8RDAZE: I hope dust will not scare you from the DSLR world...but be fully aware it IS an issue and one that you will have to deal with at some point.
