Sony Unveils Four New D-SLR Cameras

From DailyTech: Sony has unveiled several new digital cameras today in its Alpha D-SLR range. The first of the new cameras are the SLT A55 and SLT A33. Both of these new cameras are the first to use the new Sony translucent mirror design, which is where the SLT (single lens translucent) name comes from.

The a55 camera is a 16.2-megapixel camera and the a33 is a 14.2-megapixel camera. The cameras both offer fast shooting with the capability to grab continuous shots at up to 10 fps with precision phase autofocus. The cameras are also the first cams to offer quick auto focus in HD Movie mode. This provides continuous autofocus during the recoding of movies on the cameras.

The translucent mirror tech allows the cameras to split the optical path to send the image coming into the camera to both the main image sensor and an additional phase-detection autofocus sensor. The cameras also have live view with the fast auto focus mode available in live view as well. The rear LCD is a 3-inch unit on both cameras and can tilt and swivel. The only real difference between these two cameras is the resolution. Both use Sony A-mount or Konica-Minolta AF mount lenses.

Sensitivity is ISO 100-25600 and the shutter speed is 60-1/4000 second. Both cameras also have HDMI outputs and store images to SD/SDHC/SDXC and MemoryStick Pro Duo memory cards. The cams weigh about 433g for the A33 and the A55 weighs 441g and both measure 124.4 x 92 x 84.7mm.

Sony has also announced the new A580 and A560 cameras. The 580 is a 16.2-megapixel unit and the 560 is a 14.2-megapixel camera. Both of the cameras use the new Exmor APS HD CMOS sensor and BIONZ imaging processor. The cameras can shoot at up to 7fps in speed priority modes and has the Sony Quick AF Live View system with 15-point phase detection autofocus.
