I looked up the P600. The review said it's amazingly clear and sharp at the extreme end of its telephoto lens, but the trade-off is barrel distortion at the wide-angle end. The specs said it goes to 1440 mm (35-mm equivalent). Cannon's biggest telephoto lens is "only" 500 mm. Which makes me wonder if 1440 (equivalent) is really all that useful. Of course, I don't know what changes when we're talking about the digital camera "equivalent" of a 35-mm camera lens length.
I honestly don't know either. I read that too. What I did before I bought mine was to go on Flickr and search photos taken with various cameras and see what they looked like. For me, it was a good choice. Now, I did upgrade later to a DSLR.. but sometimes the point and shoot just makes more sense.
Part of my mind says that at my level of ability and discernment, there's not going to be a lot of difference between any two major name-brand cameras at similar prices, other than choices such as focal length and whether or not one wants wi-fi, GPS, waterproofing, etc. I don't feel the need for any of that fancy stuff other than a good zoom, a decent lens for the price, and image stabilization, which my little camera has, and which seems to make a big difference.
I think lobster is over-rated. Just about anything will taste good with as much butter on it as people put on lobster. OTOH, they're pretty cool to see when you're diving. I'll take grouper over lobster any day. A grouper bit me on the ear once. So a day or two later I ordered grouper at a restaurant as a revenge meal, and it was really good. Make the ocean safe for divers: Eat more grouper.
