you know when its time to clean your sensor when...

i'll be giving the 20D a clean tomorrow then.. :whistling:

Blimey yeah, you've got a bloody great airplane slap bang in the middle of your sensor :p :D



:coat:
 
the cost will probably be sky high.

sky high ?
sky... plane ?

i'll get me coat...
 
I actually laughed out loud at this thread & all the replies.

I think it must be past my bedtime...
 
Must admit I have 1 bunnie so not worth a cleanse yet as its right at the bottom which does get a crop always so no harm done lol
 
I have a whole wedding I'm editing for a mate thats pretty bad, I'm leaving the bunnies for him (it'll take weeks) It's amazing just how dirty a sensor can get.

any idea how much itll cost me to repair that?

anywhere from £40 up m8 ... get a kit and clean it your self ... i took mine to a canon agent and it cost me £60 .. now i have two 5d's i thought bl**dy hell £120 each time ..

i have now done mine 3 times each ..


this is what i do with mine .. although i do also give it a blow with a rocket blower to remover any large bits of dust ..

I've got a can of compressed air sitting waiting to be used.

If placed on a flat surface and at the right distance "I believe" it should work OK.

Will test it on a small mirror first to see if it works :suspect:
 
Just tested it on a mirror.

Nothing but dry air :thumbs:

Keeping it flat on a surface really does work :D

Next stop one of my 30D's, I'll shot the progress a little later today.

I did mine the economical way this weekend. My missus make up brush (cleaned on a piece of cloth) and a blower brush. Worked fine but I'm sure you will all be horrified.
 
UPDATE TIME

:eek:

1. Took shot of sky f/22.

2. Charged battery.
3. Mounted camera on tripod facing down, cleaning mode on, lens off.
4. Can of compressed air placed firmly on desk.
5. Quick squirt away from camera to clear nozzle.
6. Two six second bursts from the can into camera.
7. Turned off camera then fitted lens on.
8. Took shot of sky f/22. (exactly the same as the first).

9. Shot taken in anger to make sure every thing was OK, spot in this shot was not in any others after :shrug:

No problems :thumbs:

:eek: Compressed air, missus make up brush (cleaned on a piece of cloth) and a blower brush! :thumbsdown:

O.M.G....

Some of you are on a one way ticket to buggering things up.

Compressed air = moisture and you don't need that in a camera. :nono:

A make up brush that will still have residue on it even after cleaning with a cloth! :nono:

At least buy a rocket blower and a lenspen sensorklear if you can't stretch to swabs and fluid.
You can pick these up for a tenner from a reputable dealer on ebay and they work very well.

The potential is there, I'm not saying it's guaranteed but it's a risk you take.

There's also the guarantee that never taking risks will mean you never learn and will not be able to convey your experience to others :shrug:

Bad decisions come from lack of experience, and experience comes from making bad decisions :thumbs:

It has nothing to do with a good or bad decision, it's just common sense.
Personally I'm not prepared to make a decision based on your theory when I have read the views of many professional photographers and spoken to people within the industry.
It's you way of doing things and I am just pointing out the risk to other people.
 
wish i could get into mine....there is a little gremlin down at the bottom centre which i have to clone or crop out

Common sense tells me it's a bad idea, experience tells my otherwise.

Never asked you too :shrug: and because of my test it's not a theroy

So your offering me advice and telling me it's a bad idea without any personal experience of what your talking about :)

re compressed air - it will contain moisture due to the nature of the way it is pressurised into the can. whether you get it on the first burst or the 7, 8, 9th burst no one can say.

personally id never put compressed air around anything sensitive to moisture (camera, PC etc).

Sorry neil I don't want to seem argumentative.

Just nearly emptied my can doing a series of 4 to 6 second bursts on a mirror, nothing, not a drop of moisture.

Idiot proof way of blowing a mirror :shrug: not sure.

But I've put to rest, for me anyway, all the scare mongering of people who take it as gospel because they read it or heard it from a friend of a friend.

Depends on the propellant in the can - some really are just pressurised air, others call themsleves compressed air but use a propellent.

One of the other hazards is the temperature drop due to the sudden pressure change - so you get damage caused by sudden freezing - you will feel this as you do it by the can getting very cold. I have some cans that have actually got covered in ice to the point you can't hold them anymore.

Provided people are aware of the pitfalls they can avoid them - just be advised that not all cans are the same. True compressed air is fine, masquerading compressed air cans aren't!

Personally I just lick my thumb and drag it across the sensor........

Thanks for the heads up, I'll look into it more :thumbs:

thats fair enough, im not trying to start an argument either. a lot of compressed air solutions do (or at least did when ive come across them) have moisture in.

its more apparent usually when you dont hold the can straight and upright.
 
Which can/make did you use. We have compressed air cans at work, but the propellant in them is damp.

It is a T'nB

* humidity content : 15PPM max
*Propulsion by 134A gas

Totally dry from start to finish when flat, no moisture at all on a mirror.

Will be looking out for the pure compressed air cans from now on though suggested by Lensflare.
