What is the fine-grained topic of the following text: My main reason for getting my new digital camera - Canon A620 Powershot (christened "Love Bee") - is that it's small enough for me to carry everywhere and, being 'point and shoot' with manual capabilities, it gives me the option of either just pointing and shooting or 'composing' a shot by fixing my own exposure, etc. Only return the topic.
