1DX "Caution 02" Warnigns AND Filthy Sensor

Question

For those that have the Canon 1DX, Have any of you seen the 'Caution 02" (Which is to warn about a suppsoed unexpected drop in battery power)? You'll find any system warnigns under the 1: 'System Status Display' choice in the 4'th section of the yellow wrench in the menu - If you haven't viewed these before, you'll need to click on the 'system status display' - then click info, then I beleive click info again when you select one of the warnigns cautions (If you have any listed there?)
I've searched the itnernet but there is VERY little info on this issue- I've contacted canon services via email- but haven';t hearde back yet, and they'll probably want me to send it in to them isntead of just explaining what the problem might be-
I have updated firmware to latest version- but hte problem existed even before the uopdate- I've only had abotu 4 of these 'caution 02' warnings
On another note- did anyoen notice an unusually filthy sensor filter when viewign photos of sky with small aperatures (abotu f16-22 or so?) My sensor filter was absolutely filthy on a suppsoedly brand new camera, (Which was bought from Amazon.com ltd liscenced which I can imagine anyone messign with the camera before selling it since amazon's reputation is on the line- it could happen i suppose, but it would seem unlikely- I read soemwhere that the canon 6d's are arrivign with, or get filthy sensor filter shortly after firing a few shots- soem thinking perhaps a lubricant is causing dirty sensors? The grunge and dust I saw ion soem moon shots at F22 in the sky was shocking! In 3 years of usign my canon 7d with many many lens changes i nthe field, I have never seen dust dirt and grime liek htis on my sensor- but this brand new 1DX was just absolutely filthy- soem of it was dust- and fell off with compressed air, but most of it is either lubricant or really stuck on dust- I suspect it's lubricant htough as it looks morel ike grime smears than dustr particles when viewed enlarged
Have a look at this fred miranda thread to see what I'm talking about in regards to the filthy sensor filter- we're not talking about just usualy dust here- as you'll see- My sensor filter is just as filthy as the one in the link, and others in photocamel who own the 1DX have shared that their sensor filters are also filthy when they bought it new or shortly after- the amount of spots and grunge is very unusually high. I've heard from several new 1DX owners that in their years of ownign and using cameras and changing lenses etc, they have never seen the amount of filth and grunge o ntheir sensors as they've seen o ntheir new 1DX's sensors- and that too has been my experience- there seems to be an issue with the 1DX's sensor filter or soem lubricant i nthe camera splattering all over trhe filter or something- If anyone here who owns the 1DX has these two issues (The warning/caution 02) and the dirty sensor filter despite camera being new, please post your experience here- thanks

Answer 1

Nazareth,  Thanks for posting.  I see that you posted in canonrumor site as well. Members there are very knowledgeable and helpful .
Here's my take . . .
Comparing the picture you posted contra the picture posted by John Mulgrew @ the other forum site, I'd say that yours are way different in the following:
1.  lubricant / spots - is(are) what you see at the other post (not yours).  On that picture, though not 100% sure, it looks like the dirt was from a compressed air blown directly onto the chamber at the time of cleaning.  Somehow, it was as though the compressed air cartridge was almost empty and spread the debris all thru the nooks of the camera.
                In your case, if you have other pictures to examine, check if the [dark] spots are in the same location - picture-by-picture.  If they are, then it really might be in the sensor.  If not, then it is not in the sensor.
2.  smears – I have seen this from what I did long time ago with my F1 camera.  Luckily, I have cleaned the mirror, the focusing screen and the bottom of the pentaprism that faces the mirror.  If the smear was from the camera lens, you will actually notice a hazy or blurry view when looking at the VF.  It's kinda stubborn to clean this with just a swab hence, you will need a lens cleaning paper or cloth and wipe/clean it purposely.  Breath onto the lens to see where else needs further cleaning.
                In your case, the smear was as though it was a result of an attempt to clean the sensor itself by a cotton swab that has been dubbed with a liquid solution, then, was wiped or left to dry.
If you are adventureous, and not afraid to further ruin your 1DX, and this is at your own risk:  set the camera to Bulb, and while holding the shutter, clean the sensor lightly until you are satisfied with the result.  I am not going to recommend what to use.  Search the internet for the best and safest tool/application to use.
Better yet, bring and have your 1DX serviced by the nearest Canon service center.
Good Luck!
