lchiu7: Just played around with the Sony NEX-5N. That looks like a nice camera. It was $999 with only one lens so $999 for two lenses is a great deal. But the Sony store guy was prepared to bargain. My only lingering issues are reports on the web that when taking video there is a constant clicking noise in the audio and the fact to use an external mic you need the Sony mic since the adapter is proprietary.
Interesting. I bought a NEX-5N with 18-55mm zoom last weekend, and also got the 30mm Marco lens to go with it. My intention is to use it underwater, where some of the best subjects are small. Preliminary playing is encouraging, and the macro is great for macro and general images, although the 18-55mm zoom will probably be my primary above water lens.
I've only tried one short burst of video, and the audio was fine - no clicking that I noticed. Could that be the auto-focus? My wife has a little Panasonic Lumix that records a whine from this when in video mode.
The selling point for me was that you can get a 40m underwater housing for this camera for $249 on TradeMe, or cheaper if you shop direct. I've used a similar housing on the Lumix for the last 18 months at depths over 30m, and while cheap, the housing has passed the test. A more professional housing, as generally available for other cameras, will set you back upwards of $1,500. (I know you can get cheap housings for the Canon G12 & GF1, but they're not in the same league as the NEX-5N and the GF1 doesn't have a macro option)
So far, albeit with limited use, I'm pretty happy with my purchase.
