Canon has announced a problem
with too much lubricant in some EOS 1D Mark III and 1Ds Mark III cameras that can cause nasty oil spots on the mirror, on the low-pass filter, and your images. While Canon is offering to clean the affected cameras at no charge they then make the unwelcome statement; "because this lubricant is required to ensure proper operation of the camera's precision mechanical parts, it is impossible to eliminate all instances of oil scattering."
I believe most of us are well aware that some oil must be used in manufacture of any item with moving parts. However, for Canon to expect consumers to be ok with oil spatter in a camera with a suggested retail of $8000 that Canon touts as an "engineering tour de force
" is worrisome. Especially as this recall comes on the heels of two other recalls for the same camera. One recall for autofocus accuracy
issues and the other for abnormal mirror operation
