I am in th market for a nice "point and shoot" digital camera. I am currently looking at the Panasonic Lumix DMC-TZ5k on the high end of my price range, mainly due to the very nice display and the Leica lens. I do not need a digital SLR, as I have a very nice Konica 35mm SLR. I was also looking at the Nikon CoolPix S560 at the lower end. What are things I should look for. My old digital camera was an HP 4 megapixel one that was six years old. So I have very little knowledge on what to look for. I would like at least some form of optical zoom. Are there any other brands to consider (Olympus, Canon, HP)? Any help would be appreciated! My price range is $400 USD and under.
