Sensor dust vacuums

Had an Arctic butterfly and swabs for years and they're usually fine.

I seem to have a bigger issue which they don't solve... I can get the sensor spotless, only to get big twig-like blobs on my sensor a few shots later...


Here you go - imagine you've cleaned the sensor before the shoot, only to see this on your shots... I'd not changed lenses.... it's not good

Obviously there is crap in the mirror chamber or in that general area.

So my question...

Does anyone have a recommendation of a product which can safely clean out the chamber - the static brush ans swab is great for cleaning th actual sensor, but it's the "other stuff" which I need to suck out somehow

Soul destroying cloning that stuff out...

Maybe you need to take to the experts to sort it out?

What I do is clamp my vacuum cleaner nozzle to my desk. Then switch it on and hold your camera body a few inches away and use your rocket blower in the usual way.
When the dust becomes airborne the vacuum cleaner will catch it all.
It works for me.

Could it be oil spatter from the shutter?
I had a similar issue with a 1D MK3, I only found out by taking it to Lehmanns in desperation.

As"ikett" mentions I would agree this looks very much like oil splatter Ade, sorting it I'm not sure of how

I would agree with the oil spatter suggestion. I have had this on my D7000.

I've not explained it well have I

Does this explain it better

I clean the sensor before a shoot - its spotless... no dust - i test it

then after X shots, its got lots of dust (X can be between 3 and 50)

so I clean it - its spotless again - I test it to verify

then after X shots, it is again covered in dust.

I know it's not oil or moisture because there is no smudging when I use the arctic butterfly

it's dust "within the camera body" which is easily cleared with traditional methods, but returns very quickly. It kinda implies that when I clean it, the dust is being "moved" rather than "removed"

Therefore the dust is free to "move" from where I moved it to, back to the sensor.

Sounds like something is wearing in the shutter/mirror box make a quick phone call to Lehmanns, they are very helpful and will have come across the problem before and will offer advice.

Could the artic butterfly its self be breaking up - those fine fibres collecting in the shutter box then falling off as its static dissipates and the mirror blows them around?

I've also heard a few people saying vacuum cleaners work for the mirror box, some with a small tube attached to the main hose.

Also Ade shoots canon and i've only heard of oil spots on Nikon - doubt its anything wet.

Could the source be the lens chamber?

with size of those marks can you see anything on the sensor?

if so the oil/dried on goo is probably the cause- needs wet cleaning
fairly easy but takes a few passes
otherwise- get a camera shop to do it

ah just read clears at first.

is it from a disintegrating shutter assembley component - could be bits of the damping mechanism etc falling off,

may need a service

yeah - looking like a service... or just get a new camera and use the old one as backup

I'll try that hoover and blower trick though... and only ever shoot at F2.8 Wink

I gave up on Rocket blowers ages ago as all they ever seemed to do was to blow the dust around without actually ever removing any of it.

In it's place, I now have a small that I got from the Pound Shop which I use to extract dust from within my cameras.

Seems to work too, despite the crappy reviews on Amazon.

That should read "small Usb powered vacuum cleaner, that I got from the Pound Shop."

It would appear that the ability to insert links or edit/correct my posts has gone.
