The new lenses are in the store (pre-order only).
The 16-50 pancake is interesting, however reports suggest this is going to be a new 'kit lens'. I don't expect the quality of it to be better than the current 18-55, but who knows.
The "52.5mm" 1.8 is actually a 35mm 1.8, not sure why they decided to list the equivalent focal length of that lens.
The 10-18 is larger than the kit lens, but not as large as I imagined. It's actually about the size of the 18-55 kit lens. Same length, 1/2 inch wider at the widest diameter, and 1.1 ounces heavier. The 62mm filter is sort of a downer, but it is an UWA zoom afterall.
So what do you guys think? The wide angle zoom we've been waiting for is finally here. Is it too large? Is it too expensive? A NEX + 10-18 essentially makes for a $1400 P&S with an excellent sensor and the option of adding additional lenses and/or VF. In the camp next door is the RX100 for $650 with a longer (but not as wide) zoom lens, smaller sensor, no lens options, smaller overall package, and about 4 ounces lighter.
Sony definetly gives us some things to think about, and this is not to mention the RX1 (which is quite a niche machine)!
