Stain on sensor

Just bought, not a month yet, a new Ditigal Rebel and sorry to discover stains on the pictures. Since the stains always appear at the same places, they seem to be on the sensor.

Tried another lenses and the spots are still there.

I called the store that sold the camera to me and had it replaced after lots of talking.

Guess what, there is still a spot on the pictures... only one but it still is annoying...

The cameras are brand new, out of the box.....

I contacted Canon and they told me that they've never seen this.

At the store, they told me that it would take at least 4 to 6 weeks to have the sensor cleaned by Canon.....??????

Has anyone ever seen this kind of problem???

I also have a brand new Rebel....about 3 weeks old. I've taken several hundred pictures and have not had a problem. Could you send me a pic with the spot you're seeing?

Hi everyone,

I found a way to show you the pictures without having to send them through email.

I've set up an album on hpphoto.

Here is the link to the album:

I've marked the spots with a red arrow on the pictures. The spots appear as a round, slightly darker than the surrounding color, "spot".

You can view the original size photos by clicking on the picture and then click on original size at the bottom right corner

Regards,

Daniel

I looked at your photos and it is very hard to see the spots because of the image size.You can put your images on "photozo.com" and the images are considerably larger.The photos you upload can be a maximum size of 700 pixels on one side and a maximum size of 180kb.This is a free site.I am a member here and it is avery good.

Hi Jae,

You have to click on the picture and then user the original size link at the bottom right corner of the screen.

Take a look at the attachment and you'll see the "original size" link

Regards,
Daniel

Hi,

It's cloudy this morning and I took sky shots, all grey. I uploaded these picture on the hpphoto site so you can see them.

I've also marked the spots with big red arrows to make them easier to find ;-)


When I looked at the pictures on my computer I discovered two other spots that I missed defore beceause of the content of the picture and the blue sky that was probably hiding them.

I'll have a talk with the store where my new camera came from and try to settle this once and for all with Canon.

I hope that a sensor cleaning will clear the spots.

Can't access the original sized image. The site seems to do that only for the member. Which is a good thing actually. To show it here, just crop the image in tight to one of the blobs.

The way you describe the spots, it sounds like dust on the sensor, which appear as out-of-focus blobs on the image. You should not have to put up with that from a brand new camera. Either Canon's assembly work and quality control is getting shoddy, or the camera was shown to another customer in the store, where a lens was attached and in the process dust got in the camera.

I'd accept nothing more than a new one ... IF you just got the camera. IF you've been using it, you could be the one that got dust in it.

Fact is DSLRs can, and will, get dust on the sensor because the lens is interchangeable and exposes the inner part of the camera.

I periodically have to clean the sensors on my Canon 1Ds, 1DMKII as well as my MF Kodak digital backs. I do not know what Canon recommends for the Digital Rebel, but I'd read the manual carefully so as to not void the warranty. On the 10D and 1D series cameras, the manual walks you through the cleaning procedure so you can do it yourself. If I had to send my cameras to Canon every time there was a dust spot on the sensor, they would be gone more than they'd be here.

Click once on one of the pictures, you will now be in the large view screen. Then you'll see the "original size" link as described on one of my other posts.

And by the way, it doesn't seem to be dust on the sensor.

I took the camera out of the box, and face down I attached the lenses. Then I took pictures to verify if there was spots on the image, and there was. The camera is brand new, not a week old yet. The first one had the problem too right from the begining and I had the camera for two weeks.

So within a moth I had two brand new cameras with problems.

I spoke with the guy at the store and he will have yet another talk with his Canon representative to try in working something out with my problem.

The thought of dust on the sensor and having to clean it regularly really puts me off a DSLR although I believe that the Olympus has a patent method of catching the dust on to a sticky pad. Even that has to be cleaned up at service which means having regular services. To me, it is shades of cleaning a fresnel screen or mirror which is a decidedly dodgy thing to attempt.
I had a demonstration of the Canon 300D in a shop. I think the 300D is called the Rebel in the US. The shop assistant refused to take the lens off to demonstrate that aspect and try another lens for the very reason that dust could get on the sensor. I was immediately put off.
The idea of a digital camera with a fixed long range lens such as the current "bridge" cameras appeals to me but they get terrible reviews for the most important aspect - picture quality. Also they have the dreaded electronic viewfinders. So for the moment I am sticking to film and scanning (even though it is a very slow process) apart from snapshots. We have an excellent Casio which is very handy for snaps.
Cheers,
John

Trust me Daniel, it's dust not stains. No big deal. It's also no big deal to clean the sensor, because actually it isn't the sensor you are cleaning but the filter or glass in front of it. I clean mine every so often. If a dust bunny shows up on a photo I just clone it out. They usually don't even show up unless in an even toned flat expanse of sky or whatever.

I also scan films, especially B&W films. IMO, it's much easier to clone out a few dust spots on a digital shot than all the dust on a neg., no matter how careful you are at cleaning it.

Yes it is a pain removing the dust but I find that slides don't suffer from dust to anywhere near the same extent as negatives. I appreciate that it is probably pretty easy to clone out sensor dust spots but my Aria and RX also give me a decent full size viewfinder which the digital cameras I have looked at do not. I must admit though that I haven't tried the 1Ds etc. I cannot get them to try where I live except on special order which I would then have to buy - something of a risk!

I'm not waging an anti digital thing here at all. I'm all for digital when a model which suits my needs is produced. Maybe the RD1? I couldn't possibly afford the forthcoming Leica or its lenses, sadly.

Sorry if I caused offence talking of snaps. I didn't of course mean to imply that snaps is only what digital is good for, as it might have seemed from my post. I think digital is great. It's just that we use our little Casio compact for what might be termed as snaphots and very useful it is too and it produces super shots.
Nor do I have to produce wedding type pictures for sale as you do Marc or produce pictures for the press. If I did I am completely sure that I would have gone dedicated digital by now.
Best wishes,
John

Daniel, I, too, agree that my digital files are spotless when compared with the files I get by scanning slides via a Nikon Filmscanner.

When I detect dust spots I will learn to clean the cover over the sensor.

The big plus for me since I added the Canon digital Rebel to my collections is that my prints are so clean by comparison with scans before.

Dust is round because it is basically round and out of focus.

As far as scanned slides verses digital. I guarantee, I can load a digital file and clean up a few dust spots before a scanner is even warmed up let alone all the time it takes to scan at a decent resolution.

I love film and still shoot it a lot and scan my own slides and negs. But don't think scanned film can be anywhere as fast as a direct digital output.
