Sony has announced the a99 II, an 42MP A-mount SLT camera to mark the tenth anniversary of the Alpha series. It features 5-axis image stabilization and 4K video capture with no pixel binning. The camera will sell for $3200/3600, body only, when it arrives in November.
The camera will be capable of shooting at 12 frames per second with AF/AE tracking and 8 fps with 'minimal' EVF blackout. It has 79 AF points on its dedicated PDAF sensor, which work in conjunction with 399 on-sensor PDAF points to create what Sony calls 'Hybrid Cross AF points.' The system is able to focus down to -4EV.
The camera's 5-axis image stabilization is rated to 4.5EV by CIPA testing. Its shutter is rated to over 300,000 shots.
The camera's 42.MP sensor (most likely similar to the one found on the a7R II) uses BSI-CMOS technology with copper wiring for ultra-fast readout. The camera also has a newly-developed front-end LSI (processor) to cope with the speed of the sensor.
Body-wise, the a99 II is 8% smaller than its predecessor and is made of magnesium alloy. A newly redesigned shutter has a lifespan of 300,000 exposures. It has a large XGA OLED viewfinder with a magnification of 0.78x. A fluorine coating helps to keep fingerprints and oil off of the outer element. Its 3" (non-touchscreen) LCD display can tilt in 3-axis. The 'silent Multi-Controller' on the front of the camera now offers a click on/off feature. As with the a99, the Mark II has dual SD card slots. In an act of mercy, Sony has also redesigned the a99 II's menu system.
Video is, of course, also a big deal. The a99 II can capture 4K at 100Mbps (using XAVC S) with full sensor read-out and no pixel binning. A Super 35 option is also available, with 1.8x oversampling. A 'Slow and Quick' mode lets users jump between 1 and 120 fps at the push of a button. All of the capture tools you'd expect are available, including zebra patterns, time code, S-Log2 and S-Log3 profiles and 4:2:2 output over HDMI.
