Full-Frame, Dust-Free Images. Updated EOS Integrated Cleaning System specifically designed to work with a full-frame sensor. Canon’s Integrated Cleaning system includes a cleaning unit designed specifically for the EOS 5D Mark II’s full-frame CMOS sensor. The camera’s low-pass filter even has a new fluorine coating upon its surface to help repel dust. Dust that makes it past the EOS 5D Mark II’s sensor cleaning system is easily removed in post processing using DPP software’s Dust Detection Delete function, which can remove dust spots automatically from single or multiple image files
– Canon marketingspeak on their Canon 5D Mark II Camera
One of the things that pisses me off to no end is how *horrible* a job the Canon 5D Mark II does at dealing with dust on my sensor. I struggled with dust on my sensor with my old 5D so I was super happy initially to learn that the new 5D Mark II had anti-dust technology built in. Except that Canon’s so called anti-dust technology with the 5D Mark II is utter crap and pure marketing speak bull shit. The image above is an image of mine taken from a trip a few weeks ago to Miami. My 5D Mark II is less than a year old and this is the type of dust I am seeing on my images. I’d encourage you to look at this image full size here. How is this even remotely acceptable?
Granted I use my camera heavily, but I can count over *40* different dust specs on the image above.
Frankly I can tell no difference between the dust on the sensor of my 5D M2 and my old 5D without so called “anti-dust” technology. Whatever the case, for Canon to prominently advertise the 5D Mark II camera as having an anti-dust feature is false advertising in my opinion.
I posted about my horrible experience with the 5D M2 and dust over at Buzz here.
Ed Fladung suggested in that post that I give the Arctic Butterfly brush a try to remove the dust on my sensor. So I ordered one of these brushes from B&H for $112. Hopefully this helps me. I can’t see how anything could make my 5D M2 much worse in terms of dust though.
