Introduction
This guide is directly applicable only to this one specific model, nevertheless, other Canon compact camera lenses are likely to follow similar principles of operationDisassembly and methods of construction. Bear in mind, though, that the correct orientation reassembly of components is essential for reassembly. This this lens is very easy to loose track of, which will result in not difficult so much wasted time in trial and error. as requiring a fair amount of patience.

Disassembly of a Canon A3150IS lens has confirmed this. In that case the main differences were that (a) it's significantly smaller, and (b) the image stabilisation ribbon (Step 9) is non-detachable. Both these factors make it more difficult, and in the case of that particular lens a very thin and narrow section of plastic in the second lens carrier was broken, a problem that a larger lens would be less susceptible to.
