I have a problem with my new Canon EOS 700D. It hasn't even lasted a month since I bought it and have got this problem.

I noticed yesterday that when I look in the viewfinder I see some black points in the corners and the AF points kind of faded. Only the three bottom points are looking normal, but I barely see the others, including some white points/lines (dirt) appearing in the screen.

Do you ever detach/swap lenses? I ask because it could be dust or dirt that has gotten inside the mirrorbox assembly. Get a rocket blower and give the mirror and also the screen above the mirror a good blast with air. Do the back of the lens too while you're at it.

The AF points being 'faded' could be some sort of condensation within the pentamirror itself? This shouldn't happen. Do you live in a particularly humid part of the world? Has the camera been exposed to moisture? (Rain, etc?)

Either way - if blowing the inside with a rocket blower doesn't clear the dirt and dust, then as someone said in a comment on your question, take it back to the store with your receipt and get a replacement.

  • \$\begingroup\$ Dirt and dust can also get in between the focusing screen and the pentamirror. Since it is only visible in the viewfinder and does not show in the image recorded by the sensor, it is usually more trouble (and risk) than it is worth to try and clean it. \$\endgroup\$
