Cannot see through lense; Shutter locked?


I have Canon Rebel 35mm camera. After putting in a new roll of film, I cannot see through my viewfinder. Someone told me seems like the shutter is locked? The battery indicator is good, film indicator is good. I've taken the lense off and reattached and still nothing. I've read through the manual. I can hold the shutter button down 1/2 way to focus and the green light numbers come up on the bottom. However, I see nothing. I've wondered if something happened to the shutter curtains inside the film box. Can you please help?

  Not being able to see through the viewfinder has nothing to do with the shutter. It most assuredly is the mirror locked up. It should have been apparent with the lens off. You should see the mirror instead of the shutter curtains.

Try removing the battery overnight and see if it resets when you reinstall it. What lens do you have on it? Some Sigma/Quantaray lenses have an incompatibility that locks the mirror up.

  Dear Karen:
Which specific Rebel model do you own?
When you removed the lens and looked into the camera body, what did you see? Did you see the mirror, the shutter blades, or the film?
Have you opened the back of the camera and looked at the opening where the shutter curtains should be? What do you see? Normally, you should see a series of black horizontal blades, overlapped like a closed window blind.
For many years my customers brought in cameras with locked up mirrors. Often I saw one of three problems:
1) The shutter blades were pushed out of place, perhaps by a finger. I could very often, using laytex gloves and small flat blade screwdrivers (to the tips of which I had glued slivers of small-cell artificial sponge), gently coerce the blades back into place. Once the blades were back in place, they could complete an open-close cycle, the mirror dropped down again, and the camera functioned normally. I strived to avoid getting fingerprint oil on the shutter blades, hence the gloves.
2) A low or weak battery caused the mirror to lock up. Changing the battery solved the problem.
3) Impact damage, extended exposure to vibration (Do you travel by motorcycle?) or water damage caused the mirror lock up.
I'm guessing the first two causes are more likely. You could rewind the film in the camera and use a leader retriever to pull the leader out of the cassette (such a device is inexpensive, and available at a camera store) so that you can use the film later, or you can "write off" the roll and just open the back door and remove it, so that you can examine the shutter blades.
It's been my experience that if something has prevented the shutter blades from completing an open-close cycle, the mirror will stay locked up.

  I'm thinking maybe the aperture release on the body isnt grabbing onto the aperture switch on the lens, and your aperture isnt opening inside the lens,so it would be very dark through the viewfinder, almost black.. I had that problem with my Nikon D100 once
