The Rebel K2 has the Canon EF mount. It is compatible with any EF lenses except the EF-S series. It will also work with third-party lenses that are compatible with the Canon EF series.
You can see the entire current line of Canon lenses (including the EF-S series) at http://www.usa.canon.com/cusa/consumer/products/cameras/ef_lens_lineup
Vignetting cannot be eliminated, though some programs like Photoshop can correct for it.
On some zoom lenses, you can reduce the amount of vignetting by shooting at a higher zoom. For example, if your lens is 24mm - 70mm, you will get more vignetting at 24mm than you would at 70mm.
That's normal. The Digital Rebel works as SLRs have worked for half a century, using the viewfinder to frame and compose your pictures. Only the more recent dSLRs have the Live View capability to allow you to use the display to frame and compose your pictures.
If you are getting some photos where only part of the image is visible, then I suspect that they were photos where you used a flash.
Cameras have a specified maximum shutter speed for use with a flash, this is called its 'sync speed'. This is the fastest speed that the camera will need to open the lead shutter and close the trailing shutter in order to expose the entire surface area of the image and have it evenly lit by the flash unit. If you shoot too fast of a speed, then the shutter will only be partly completed its exposure and you'll get a photo with only part of the image showing. The faster the speed past the sync speed, the less the resulting area of the image. Most cameras will have a sync speed of 1/250 or less. I think a lot of the Rebel models are 1/90 - consult your manual.
If it's an older lens, for EOS film cameras, Quantaray might upgrade it free - contact your local Ritz Camera store ( it's imported by Ritz ) or find a repair center for Quantaray online.
The green rectangle is full automatic. You can use the P mode for the same function. In the P mode, you can change settings, in the green rectangle, you cannot.
The standard canon 75-300 lens is not considered a "fast" lens. Because of this, when zooming in on objects you are actually reducing the amount of light hitting the image sensor. Fast lenses cost $$$$. Just google "Canon L Glass" and you will see what I'm talking about.
Try opening the field of view (zooming out) to allow more light to be absorbed bu the image senor. Crop your subject later in whatever software you use. You can also use one of the manual modes and up your f-stop to make the camera more sensitive to low-light conditions (higher f-stop means higher film speed.. higher film speed is how fast the "film"... aka image sensor absorbs the light. for action photos, faster film speed is key!!).
have fun experimenting.
