5. Dust Removal
Dust is an anathema of digital technology, and camera manufacturers have to battle it. Each one has its approach, but the basics are the same: The low-pass filter of the camera’s sensor is mounted on a system that produces very rapid micro-vibrations. Canon, Pentax and Sony also use an antistatic treatment that reduces the sensor’s electrostatic attraction. Nikon, for its part, has equipped the D60 with an air-flow system in addition to the vibration system. The air-flow system directs a stream of air into the chamber to clean the sensor.
The most reliable system, not surprisingly, is the one used on the 450D. Canon was the first vendor to develop an effective system against “dry” (non-sticking) dust with its 40D. Note that the 450D also has a system for mapping dust and then batch-processing images to remove its effects later.
Sony: Good but Not Perfect The Sony system works fairly well. After several days of intensive outdoor use, only one dust particle was visible on our pictures’ images. However, one small puff of air from a rubber puffer was enough to remove it – which implies that it was dry dust. So the vibration system, which should have eliminated it, could be improved.
The D60 and K200D are still too vulnerable to dust. With the Nikon, the technique used was developed very recently, and should improve in later versions. Pentax has complemented its vibration system with a “dust alert” function that helps spot parasitic dust on a test image on the rear display. This solution, which we support on paper, is only really useful when you have the time and the means to clean dust away manually.

The Nikon D60 and Canon EOS 450D/Digital Rebel XSi are two different cameras.
I think my employer is bad for forcing me to double check and proofread my work. Dr. Tom doesn’t even require you to care about your job.
BTW, for camera review, I’d go to dpreview.com and not Tom’s.
This should be "...The Nikon D60, Canon EOS Rebel XSi/450D, Pentax K200D and Sony α350.
Technically, the XTi(400D) was the first to implement the eos integrated cleaning system; the newer 40D uses the same system.
I fail to see why anyone would want/need a physical button for changing between RAW and JPEG shooting modes.
I don't know if the other software has this, but Canon's Digital Photo Professional also has good aberration correction features (distortion, CA, light falloff, etc.)
If you shoot with Canon, another good review site is http://the-digital-picture.com/

Only Olympus Dslr's have the most effective dust removal system and they were the first that designed it and implemented it
The first model that had this feature was the Olympus E-1 back in the late 2003
aside from above comment on the dusk cleaning system is pioneered by olympus, the "New" DSLR in this guide are hardly new.. all of them are announced back in Jan(and as we ALL know, 1/2 yr is a long time for tech).. there are new budgeted DSLR released recently such as canon 1000d, olympus 420/520.
40D, e200, a430, 500r, g650, l,m,n,o,p,q...
I don't know about anybody else, but it would have made the article a lot easier to follow if they just referred to the cameras by their manufacturer name (after initially identifying the models). When the last reference to (or photo of) a camera by it's manufacturer is 2 pages back, it's a pain to figure out which camera they are talking about. Unless you're a serious hobbyist or professional, it's hard to follow the reviews when they switch between modes of reference. We all knnow the names Sony, Pentax, Nikon, and Canon; stick with them for clarity.

I'm surpirsed that Olympus was not included in this review. They have some of the lightest bodies that are cost effective. For those interested in getting into photography - Camera bodies are not as important as Lenses and Olympus makes the best lenses in the market.

Yes, lens with no camera is great.
