Does anyone have comments on this camera? Use it currently? It seems to be what I am looking for: 1. Primarily quick point & shoot to get action photos while hiking & rock scrambling. 2. Option to go manual focus/time/f-stop for landscape shots. 3. Optical zoom. 4. Very doubtful I will purchase addtional lenses so don't need true DSLR All comments are appreciated. Thanks in advance.
