today's exchange @66 is roughly HK$12,800 !!!
Sony has announced the Alpha 7 II, which the company has managed to keep very close to its vest. The big story on this 24MP full-frame mirrorless is its 5-axis sensor-shift image stabilization - the first of its kind in a full-frame mirrorless camera. Sony claims that this IS system can reduce shake by 4.5 stops using the CIPA standard. If an E-mount lens with OSS is attached, the camera will detect it and use a combination of in-lens and in-body stabilization.
Like the original a7, the a7 II features 117 phase detect and 25 contrast detect points on its CMOS sensor but Sony is claiming a 30% improvement in the a7 II's AF speed and 1.5x better tracking performance than its predecessor. Sony says this is thanks to its 'proprietary image analysis technology' using more information from a scene to keep focus locked on a subject.
On the video front, the Alpha 7 II now supports the XAVC S codec, which can record 1080/60p video at 50Mbps. The camera also supports S-Log2 to capture a wide dynamic range in video for grading.
From a design standpoint, the biggest changes are the grip - which is larger - and the addition of a front dial. The shutter release button has been moved to a more natural position on the grip and the front panel is now magnesium alloy instead of plastic. The lens mount has also been reinforced, for more stability when using heavy lenses.
The a7 II is expected to ship in Japan on December 5th. No word yet on availability in other regions.
