How often do you clean your sensor?

I haven't found that the sensor cleaning does anything to dust spots on my sensor. Have done the test shot before, then the sensor cleaning then test again. Spots are the same.

Then rocket blower, test shots, spots same.

So when I get spots I seem to need a wet clean (all on my 5DM2)

Ursula,

It seems as if you may have somehow gotten something on your sensor other than dry dust. That could be why you needed a wet cleaning.

Not sure how on earth anything other than dust could have gotten on your sensor, except that maybe some type of lubricant was at one time used on your body or lens? Or maybe lens cleaning solution was in use when there was no lens on the body and the mirror was up? Not sure how that could happen, but I can't think of any other way anything other than dry dust could have gotten all the way past the mirror / shutter assembly and onto the sensor.


"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".

Other than changing lenses, how else would dust get onto the sensor?
The only reason I ask is that I have never cleaned my sensor and don't have any spotting in my shots. I only have two primes (50L & 35L) and pretty much keep the 35 on all the time. Should I be going through the cleaning exercise even though my shots are spot-free?

some fire of shots without the lens attached or the body cap on which is rough on the sensor and the mirror can instantly get dust on it even when changing lenses.

from what i've heard from experienced photographers you should only clean your equipment when you notice spots or dust in your shots. mostly the sensor, lens cleaning is quick and easy, but still have to be very careful.

one way to detect is by looking at a white wall or just a sheet of paper on a wall, and fire off a long exposure (10 secs or longer) exposing the sensor for a long time allowing it to show any defects or dust that might've caught up on it.

Many or most spots won't show up unless you are shooting a "smooth" scene (such as a sky) at a narrow aperture, f/8, f/11, etc. If you are in the habit of shooting "busy" scenes and especially at wider apertures spots may not show up at all.

So, you can say "what's the bother?". That's true until you see that nice landscape that you really want to capture, get a great shot, and then open it on your computer to see all these dang spots!

So, the way to determine if you have spots is to stop your aperture down (f/16 is a nice testing aperture) and take a shot of either a clear blue sky or an overcast with nice smooth light gray, or even a white wall, and see for yourself!

Tom , I've spotted spots on the first Image of yours I looked at that I thought spots would show up in..:p

Fantastic shots you have though, really impressive.

When I get around to it, which is usually at the point that the dust bunnies start to annoy me.

Wow - that one's an oldie! Taken back when I first started doing this. In fact, that was taken back before I even had a rocket blower, or knew about them, for that matter.

Yes, you're right - I do frequently have spots. I never claimed that I don't get spots from dust - I frequently get tons of spots from dust . . . that's why I have to use the rocket blower so frequently and blast the dust off.

If I remember correctly, it was in the fall of 2008 - my first year photographing deer!

Wherever you read that - it's wrong.

The 5DIII will be using a system similar to, possibly better than, the one on my 7D. And that hasn't been cleaned for over 2 years - and still doesn't require cleaning.

Back when I used my 10D, 20D, and 30D, sensor dust and oil were a nightmare that took a lot of the joy out of photography. I remember being reminded constantly by Olympus users how much better their cameras were because of the built-in sensor cleaning. I have never needed to clean my 50D, 7D, 5D2, or 6D. The few times I've had a speck or fiber with these cameras, it disappeared with a power cycle, or worked its way off during a series of shots.

Never clean a sensor "just in case". Taking a chance of scratching the sensor or breaking the mirror, to solve a non-existent problem, is not a good policy.

One tip to reduce the possibility of letting dust in is to have the lens pointing down when swapping lens. Unless there is blowing dust gravity will keep the interior dust free.
