Does removing the lens from a film SLR camera destroy the whole roll of film if the film is already inside?

I'm using a Rebel K2. My sister didn't know that I already loaded it with film when she decided to change the lens. I had some shots in there for my class, and I'm sort of hoping that they're not ruined.

The SLR camera is mainly designed for interchanging the lenses and shoot .So don't be worry nothing will happen even if you interchange the lens, with the film inside.
The film gets spoiled wholly when you open the back door.Most of the canon is pre-winding models(check with the user manual) the taken pictures won't go even if you open the Back door,Only the snaps to be taken will get fogged.
If it is a winding model then the some snaps or the taken photographs wholly gets spoiled depending on the time you kept the door opened.

While interchanging the lens ,accidentally you pressed the shutter lever without turning the power off, you might loose only one snap.

You'll be fine. The reflector door is tight to the camera body, allowing you to change lenses. Just don't open the film door.

:)

your pictures should be safe as long as no one pressed the trigger/

Nope. Just don't hit the shutter release.

Hi !

Just us others said: I the sutter was pressed.. then you could have some problems.. but only with the last picture.

I would like to say more... but hemanth k have said it all !

thanks !

The lens you can change just don't open the film door.

no, you can change the lenses as many times as you'd like .. just don't open the film door.. that's what will expose the film to light and ruin the pictures..

they are not ruined...switching lenes while there is film in the camera has no effect at all on the film...light does not enter the camera.
