RichRMA: If this, by some miracle came in with that fast 16-50mm f/2.0-2.8 for say $1299, it would be a crazy bargain. However, I think it'll be closer to $2000.00.
According to imaging-ressource, the sensor has been improved (lower noise at high iso and possibly wider DR at low iso) by means of a new manufacturing process (using copper instead of aluminium...). See http://www.imaging-resource.com/PRODS/samsung-nx30/samsung-nx30A.HTM
jonathanj: It looks like the NX30 uses a different battery from the NX20 (and NX10), is that right? Is it the same one in the Galaxy NX or a totally new one?
Battery for nx30 is BP-1410 while NX10 and NX20 use BP-1310. The new one has more power (1410 mAh) but it looks very similar... Retro compatibility would be a welcome reward for the existing NX users :-)
peevee1: The mirrorless field just got a lot more compatible, with NEX and NX filling the glaring holes in their lineups. m43 is still ahead with extra f/2.8 zooms and excellent tele primes still missing from other systems, but the prices for those are insane.
@AV Janus :Is 76,5mm (50mm on APS-C) less weird than 67mm (45mm on APS-C ?
