Canon EOS 5D Mkii Owners, Auto Sensor Cleaning?

I'm currently shooting with a 5D MKI and a 100-400 lens. It's a great combo and I love it but, the lens is a dust pump and likes to deposit dust on the sensor. The MKII has something called integrated cleaning system. I'd like to know if this works as advertised or if does not live up to the hype. Also, does this system and how it's integrated into the sensor interfere with sensor swabs if they're needed?

I know DPP can be used with the MKI to manually remove spots and you can do it in Photoshop as well which, I do. But, the literature on the MKII located here:

http://www.usa.canon.com/consumer/co...139&modelid=17662#ModelFeaturesAct

Seems to imply that you can use DPP with the camera to have the spots removed "in camera".

"This Dust Delete Data image is analyzed in-camera, and the location and size of any remaining dust is subtracted from any subsequent pictures taken"

It seems this is available with the Digic4 equipped camera so that means 40D or higher. It's discussed briefly in this topic from 2007:

Canon Rebel Sensor Cleaning Systems (by ACDC8 Oct 18 2007 in Aviation Photography)

But, it's now 2009 and I imagine more members here have had some hands on time with it and I'd like to hear about their experiences.

Thanks for any insight.

The integrated sensor cleaning system is available on a few cameras including the 50D I use. I've found it to be pretty effective but it's not perfect. I still clean the sensor when I notice dust becoming a problem (I hate cloning dust spots!). I've never used the dust delete data software as I prefer to have a clean sensor than have software take care of it. Dust delete is only as good as the data provided to it.

G'day Cvervais
Ive used the auto system onthe 40D 50D 1Dmk3 and 1Dsmk3 and have found it to be excellent.
It his great in the field and extends the time between swabbing considerably.
I use auto clean after each lens change and have found it very effective at getting rid of most stray dust particles.
Definitely a bonus if you are considering an upgrade and from here highly recommended.
I dont use the dust function in DPP a i use CS3 and have found the amount of dust is now so small its not worth the effort. Also im generally changing lenses quite a bit so any new dust wont be in the dust profile.

D700 has something similar (as does most Nikon DSLR cameras) when used with Capture NX or NX2. It's not totally effective to be honest. I imagine both work in the same way.

And if you change lenses or have the sensor cleaning work, the profile is likely voided. It's better to use a Giotto blower and or a wet cleaning system if you need to.

Honestly, why not just try it yourself and see if it works. My 1DMkIII cleans itself everytime I shut it off.

Ok, so the cleaning system does not interfere with being able to swab it then?

I've thought about renting a MKII to see how this feature works but, a weekend of photography I don't think is going to compare to the hands on time a lot of folks have here.

Yeah, I've got the blower and it works for some of the spots but, the 100-400 being a push pull lens and not weather sealed likes to suck and blow dust around.

Thanks for the insight so far.

No, it won't. But it will interfere with "Dust Delete Data" reference images - since they can not possibly be accurate after sensor cleaning has run. That's why those things are not very useful. Also - they depend on you using the camera manufacturers own software - rather than industry standards like Photoshop.  Sad

Otherwise - you can swab it if you need to. Be careful with what you use on the swabs on some of the newer cameras - certain types of Eclipse are intended for specific cameras. The blower should be quite fine to use with a 5D Mk.II, since it has its own auto-cleaning system.

For the rest, I do this:

That's how I clean the sensor in my D700, using a cleaning stick, Silbon paper and a specific ethanol based cleaning solution, swabbing outward in a circular motion from the center.

I had a couple of spots in my A200 and the cleaning system worked!
