I went for some shooting fairly warm/sunny day. I took 3 shots, everything was normal. But then all of a sudden, the camera started producing shots like this:
I didn't know what it was (still don't know) and I checked some things. My lens, my settings, all seemed fine.
I took a look at the inside of the camera. I didn't see anything wrong there (but I don't think I would've spotted something wrong if there was anything, unless it was hanging loose...)
The first 3 shots I took are ok, I can view them with no problem, so it's not the LCD screen either.
What is/could be the problem and what do you suggest?

I had a similar problem on my 300D.
Looks like your AF sub-mirror (a small mirror behind the main mirror) as a broken spring making it not going up along with the primary mirror. You can check this by removing the lens and shooting a few frames while looking via the lens mount. You'll probably see that the main mirror goes up, but the secondary doesn't, so half your picture is covered.
If this is the case, the mechanism needs replacement, either in the local brand representative or something along those lines.
You can still use the camera, if you really need to, by making the secondary mirror go up by hand until it adheres with the primary mirror. I was able to do this easily. You'll then see that the camera loses AF, so you'll have to switch the lens to manual and focus by hand.
This is a very common ocurrence on the 300D, unfortunately.

Quoting AirKas1 (Reply 5): just did what Tim said. If I press the shutter halfway, nothing happens. If I push the button all the way, the mirror goes up and then down again very fast (it makes the photo-taking-noise).
That is what should happen.
When the mirror is down, the light coming through the lens is reflected via a prism through the viewfinder. When you open the shutter (i.e. take a shot), the mirror moves up to allow the light coming through the lens to reach the sensor. As soon as the shutter closes, the mirror flips down again.

This exact thing happened to me while I was in LAX. If you turn the camera off, take the lens off and physically push the main mirror up, you'll probably see the sub mirror dangling there like it isn't suppose to. This happened on my first day of 3 in LAX and I needed an immediate fix so I had to go to the nearest building to me on Imperial Hill, a mortuary, and borrow scotch tape and i took a tiny (1 cm or so) piece of tape and taped the sub mirror the main mirror. However, that sub mirror determines your autofocus I learned later because after that, I had to manually focus ALL my shots. It was the biggest pain but a lesser disappointment then the idea of the other 2 days of shooting not being able to happen. I had mine fixed by Mack Cam because I had a 5 year warranty on it. It was fixed in 2 weeks for free and came back fine. That camera is currently producing pics for this website to this day by photographer Edward J. McCoy .

Try to check the mirror flip on a longer exposure. Ofcourse you are risking dusts on the sensor but hey, the dust issue is not big a deal when compared to the mirror issue. The mirror should be vertical to the sensor when capturing the full photo.

Bummer to hear about your camera Kas.. Hope everything gets back to normal soon When I dropped my camera (just over a year ago) I sent it to Canon in California and I had it back in less then two weeks.

That's a bummer. My 300D also broke and fixing it here will take two months or more at a very high price so I decided to buy the 350D and guess what, now this camera has a softness problem as almost all my photos are not sharp and more to the soft side. After asking around it may be my lense (Canon EF90-300mm 1:4.5-5.6 USM) so I might have to bring it back to the store too and hope the problem isn't major (even though I still have a guarantee on it). I just can't live without my camera for a long period.....
