S = Single L = Lens R = Reflex
I think you mean "SLR". It stands for Single Lens Reflex.
A photographer also uses a lens protector, a stand, an interchangeable lens, and much more equipment.
IS means 'Image Stabilizer' where in Canon Camera's a portion of the lens is moved to counteract camera shake which can cause blurry images.
To remove a camera lens, first locate the release button or switch on the camera body near the lens. Press or slide this button to release the lens. Then, gently twist the lens counterclockwise to unscrew it from the camera body. Be careful not to force it, as this could damage the lens or camera.
No, this is a point & shoot camera and there is no lens mount. The lens is fixed on the camera and cannot be removed.
You can't. The lens on a Canon SD950 is integral to the camera body. Trying to remove it will ruin both the camera and the lens.
To create a DIY macro lens for your camera, you can use a small magnifying glass or a reversed lens from an old camera. Attach the magnifying glass or reversed lens to your camera using a lens adapter or by holding it in front of the camera lens. Experiment with different distances and angles to achieve the desired macro effect.
