There's a whole swarm of gadflys around here.
A camera that cannot zoom in or out has a "fixed focal length" lens. Most inexpensive cameras come with a fixed focal length and it will tend to go toward the wide angle. The typical point and shoot camera may have a 35mm or 45mm focal length lens. If you shoot your art work with this type of focal length, whether it's a $50 lens or a $1000 lens, film or digital camera, I think it will warp the edges. The bigger the canvas the more evident this will be.
Keep the face of the canvas as close to perpendicular to the direction of the lens as possible. Set the focal length (zooming the lens in or out) to 80mm to 100mm, then position the camera as close as you can to the canvas still seeing border to border, and shoot.
I think that's the way it works.
