Not A Pretty Sight

This is from my second brand new 400D.
Admittedly it is not quite as dramatic as what you are seeing but none the less not too good from a new camera.
I studied (out of frustration) the contamination and found it to be oil.
I can only assume it is the lubricant used on either the mirror or the shutter mechanism.
Having spoken to others about the problem, mine was not an isolated case.

That said, I could remove it with IPA swabs and, after a time, the problem lessened but never went away.

I understand this is of little consolation I just thought it may be of some passing interest to you.

Hiya Fordmondeo,

Hell what happened to the first or shouldn't I ask.

Mmmm the more I seek out info on the 400D the more it looks like there are a number of poorly made ones around with similar fault, guess they've never heard of quality control in China eh

Thanks for your input

Cheers for now
Mark

that sucks, i'd take it straight back whence it came. 'Made in Japan' always makes me feel more confident. 'Made in England' would intrigue me.

I was pretty sure that Canon still makes their cameras in Japan, or is that only their pro cameras now? I'm not a fan of made in China, but companies are going to China like Moths to the flame because of the dirt cheap labour. Price over quality...

Hiya Skylab, Gordon,

I don't think this is ' Dust ' as it is stuck fast, it definately seems to be oil based as it smeared when I used a brush which had been totaly clean & tested before use, that piece of Crud that looks like a S looks just like Eye Liner goo under a Magnifying Glass & it appears so have shiny particles in it

Cheers for now

This looks like biology slides we had of fungus and bacteria.

Really.

Does it smell funny?

The first when straight back to jessops for a similar (but worse) problem.
The most annoying thing was, the jessops staff accused me of not fitting the lens under "clean room conditions".
I did point out that when Canon make a 10-600mm f1.2 ef is usm do lens, I would let them fit it and then I would not have to hire a clean room to change lenses.

Hi Mark
Its always scares me to death cleaning the sensor but I've only had to do it twice on my 350D. I used digipads and ecplise fliud. The 400D does need a different eclipse fluid to the 350 I would check that you have got the right one.
I am always changing lenses and putting on tubes, normally in a field in the middle of nowere, I havent checked my sensor for a while it probaly needs doing again.
I've never used mirror lockup though.

i've never read that different sensors needed different cleaning fluid- I assumed Eclipse would do any sensor albeit ideally with different sized swabs. Do you have a link explaining this?

Not sure about the link but Mark is correct- the 5d and 400D have different IR coating on the glass which can lift off with the original eclipse fluid - they do another fluid E2 which is safe for the newer coated sensor filters.

okay, I better find out if I need the new version for my 1D MK3 - that could be an expensive mistake!

Sorry dont have a link it was a while ago that I read this but I think warehouse express do both types of eclipse fluid

According to this http://www.cameraclean​.co.uk …echnical/sensor​_specs.php
you should be using E2 on it

5D still uses the old Eclipse, but the 40D and the new MKIIIs use the new Eclipse E2 (because of different coatings on the AA filter).

Remember, though... you're not cleaning the sensor. You're cleaning the glass filter on top of the sensor (which is actually a lot cheaper to replace than a sensor should something go horribly wrong). The reason for the different formula is the different types of coatings they use on the glass. A single swab with the old eclipse is NOT liable to cause any noticeable damage to the new coatings, but they will wear away with repeated cleanings, so it's probably best to use the right fluid from the get go.

ok Warehouse Express dont seem to have the Eclipse 2 but told me Vdust plus (previously Vdust formula) is suitable.

Looks like a micro worm and the eggs of a micro worm. So did you drop it in the sea Mark?
Hope it's not away for too long getting sorted mate. I reckon it's summit to do with when it went away before as you had problems when it came back from repair with dust if I remember correctly.
