To Wayne and the group,
It reads like you are going to throw the baby out with the bathwater. The Canon 5D is a fine camera and you seem to be using it well. You have to learn how to deal with dust, as I did with my 1Ds. I reject the idea that other DSLRs collect less dust by virtue of some design feature.
I am surprised to read that you have tried the Copperhill cleaning technique and still have that mess of specks. Either you are not applying enough pressure to contact your cover glass, or your methanol is contaminated. I am not aware of "bubble pack plastic" having any stiff parts. Try a piece of credit card or a tounge depressor. I use a cut down spatula, PEC pads and Eclipse fluid for the stubborn spots. For 90% of my cleaning, I used a charged, dry brush from Visible Dust.

I'm starting to do more macro work with my 5D, in which high F-stops are common. At high F-stops, dust becomes more in focus, while at lower F-stops is not visible (below F11-16). Here is a macro shot I made yesterday at F32 using 180mm macro plus 1.4x converter. Notice the dust on the right. http://www.airsprite.net/OM/dust_MG_3717.jpg 100% crop of right side: http://www.airsprite.net/OM/dustcrop_MG_3717.jpg This dust is not affected by using a CO2 duster, so I'm beginning to wonder if the origin of the dust is from the camera itself, such as lubricants. The visible dust website http://www.visibledust.com/nature_of_dust.html mentions the possibility of metal or lubricants from the camera itself. I'm wondering if this becomes more of an issue the more the camera is used. Not that the small size of the particles become nearly invisible at F8 and below, so may not be noticed much by many photographers. Only when high F-stops are used does it become a problem. I have not used a visible-dust brush, but only a PecPad and my own plastic utensil (made from stiff bubble pack plastic) and a couple of drops of methanol to clean this. I'm open to suggestions on how to deal with this problem. I'm beginning to think the 5D is not the ideal camera for macro work, and that a 20D or 30D would be a better choice.
