The Sony α77 II ( ILCA-77M2 ) is a SLT camera ( single-lens translucent ) - a digital camera similar to a DSLR camera . The camera is the successor to the α77 and was introduced on May 1, 2014. In contrast to other SLR cameras, the camera does not have a conventional folding mirror, but a partially transparent mirror and an electronic viewfinder.

Changes

The following changes have been made to the previous model:

  • A newly developed image sensor with the same size and resolution is installed.
  • Use of the Bionz X image processor.
  • In addition to red, green and blue, the LC screen also has a white subpixel with the same effective resolution of 640 × 480 pixels (1,228,000 subpixels vs. 921,600 subpixels).
  • Autofocus module with significantly more autofocus points: 79 AF points, including 15 cross-type sensors with a central f / 2.8 sensor (predecessor α77: 19 AF points, including 11 cross-type sensors). 4D Focus, more AF modes, e.g. B. EyeAF and Enhanced GroupsAF.
  • The camera no longer has a built-in GPS module.
  • Built-in NFC and WLAN modules.
  • Three freely configurable camera modes that can be selected directly (with the predecessor, after selecting the "MR" mode, 1–3 had to be selected using the joystick).
  • New multi-interface flash interface (now compatible with ISO flashes).
  • The camera shake protection built into the housing does not only take effect when taking a photo, but as soon as the shutter button is pressed halfway. This creates a stabilized viewfinder image.

  3. ↑ Sony (along with other manufacturers) counts the subpixels of each pixel, i.e. H. the red, green and blue channels of each pixel individually, and therefore specifies the viewfinder display with 786,432 [pixels] × 3 [color channels] = 2,359,296 pixels.
  4. ↑ Sony (along with other manufacturers) counts the subpixels of each pixel, i.e. H. the red, green, blue and white channel ( RGBW ) of each pixel individually, and therefore specifies the rear display with 307,200 [pixels] × 4 [color channels] = 1,228,800 pixels.
