The HX30V is the only one that's entirely new, though. It's a compact megazoom with a 25-500mm lens, or 20x zoom. The HX20V is the same camera, but it's missing one feature, the HX30V has: built-in Wi-Fi. The Wi-Fi can be used to back up to directly backup to a computer, send to online sharing sites or Sony's PlayMemories cloud storage service, or for transferring photos and video to a smartphone.
All but the H90 feature a new 18-megapixel Exmor R BSI CMOS sensor paired with a Sony Bionz image processor. The combo allows for things like enhanced low-light shooting capabilities; faster autofocus (always a good thing, especially on megazoom cameras); Sony's Clear Image digital zoom that doubles the optical zoom while keeping full resolution (apply grain of salt here); improved image stabilization while shooting movies; and dual recording of 13-megapixel photos and full HD video. These also all have built-in GPS with log recording and 3-inch 921K-dot-resolution LCDs.
The HX200V has the same body and lens asand likewise, the HX10V is the same as the . But again, the new models get the new image sensor, faster AF, and enhanced shooting options.
The H90 has the same lens as the HX10V, but uses a 16-megapixel CCD sensor, so you don't get a lot of the shooting features found on the higher-end HX models.
The HX200V arrives in March for $480; the HX30V and HX20V show up in May for $420 and $400, respectively; and the HX10V and H90 hit stores in March for $330 and $250, respectively.
