Hands On Sony A99 Mark II – 4k Camera

Sony A99 Mark II, an 42MP A-mount SLT camera to mark the tenth anniversary of the Alpha series

Sony A99 Mark II features 5-axis image stabilization and 4K video capture with no pixel binning

The camera Sony A99 Mark IIwill sell for $3200/€3600, body only, when it arrives in November.

The Sony A99 Mark II 5-axis image stabilization is rated to 4.5EV by CIPA testing. Its shutter is rated to over 300,000 shots.

The Mark II 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 Sony A99 Mark II has dual SD card slots. In an act of mercy, Sony has also redesigned the a99 II’s menu system.

Sony A99 Mark II video is, of course, also a big deal. The a99 II can capture 4K at 100 Mbps (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.

Focus Modes: Unleash The Power Of Your Sony a77 mark 2

This is the introductory chapter of the detailed premium channel segment on the Sony a77 mark 2

Showing every feature and detail of the Sony a77 mark 2 and what Gary Fong’s recommended settings are.

Sony a77 mark 2
Among what is covered is the “12” fps mode (which fixes the camera’s aperture but let’s ISO and Shutter speed vary to capture correct exposure while maintaining speed) as well as the new locking focus variable flexible spot mode.

Although Sony stresses that the A77 II shouldn’t be compared to pro-grade cameras because it’s much less expensive, it is starting to gain the kinds of specifications that – at least on paper – suggest it could be capable of punching considerably above its weight. For instance, the improvements to the A77 II’s autofocus system extend a long way beyond the focus sensor itself.

The Mark II gains a range of subject identifying technologies that Sony has introduced in recent models. As such, it offers Eye-AF, rather than just face detection. It also gains the most advanced version of ‘Lock-On AF’ that we’ve yet seen, which will allow you to specify an off-center starting AF point. Previously most Sony’s assumed your subject was the thing at the center of the frame, when you started tracking.

Sony SLT-A77 II key specifications:

  • 24MP CMOS Sensor with gapless, offset microlenses
  • 12fps continuous shooting with autofocus (up to 60 JPEGs)
  • 79 point AF module with 15 cross-type AF points, covering 40% of frame
  • Increased control over AF behavior
  • 1080p60 movies with autofocus
  • Audio level, monitoring during movie shooting
  • 2.4M dot OLED viewfinder
  • Pull-out three-hinge tilt/swivel 1.23m dot White Magic LCD screen
  • Built-in Wi-Fi with NFC
  • 1/8000th maximum shutter speed, shutter rated for 150,000 actuations
  • ISO 100 – 25,600 (Extendable down to 50, and up to 51,200 with multi-image combination)
  • Auto ISO customization
  • Optional, profile-based correction of vignetting, chromatic aberrations and geometric distortion
  • Top panel LCD
  • Stereo microphone and external mic socket
  • AF Micro Adjust

Sony Alpha a7R II Full Frame Mirrorless- 4k video

The Sony a7R II is here in all its high-resolution

back-illuminated, 4k video, stabilised glory!

Take look at Sony’s Canon-killing full-frame mirrorless to see if it’s really as good as we all expect. Now, even more comprehensive quality enters the picture. With the world’s first back-illuminated 35mm full-frame CMOS image sensor with 42.4 megapixels. The Sony α7R II takes image resolution, sensitivity (up to ISO 102400) and speedy response to new heights. The Fast Hybrid AF system’s dense extra-wide focal plane phase-detection AF coverage keeps a subject in sharp focus entirely throughout the frame, while 5-axis image stabilization reduces blur which otherwise tends to affect handheld shots. High resolution is further enhanced by Video 4K movie recording, featuring full pixel readout without pixel binning. With so much insight packed into such a compact form, it’s clear that there is more to life than meets the naked eye.
