Sony ILCA-77M2 + SAL1855
Ultra-high resolution Exmor™ CMOS Sensor
Enjoy an upgraded APS-C format sensor with 24.3 effective megapixels. Sensor offers 20% higher sensitivity than the previous model, for flawless, low-noise still images and Full HD video.
BIONZ X™ processor
Enhanced processing engine handles enormous amounts of sensor data to allow very high-speed shooting of superb, low-noise images.
79-point phase-detection AF system
Newly developed AF system with 15 cross sensors for accurate, non-stop autofocusing - effective with Viewfinder or live view on LCD.
Proprietary Translucent Mirror Technology
Sony’s unique design replaces a DSLR moving mirror with a fixed translucent mirror, which enables ultra-fast shooting with continuous use of accurate phase detection AF.
12fps with AF tracking
Capture fast-moving action with razor-sharp tracking, at up to 12fps (approx. maximum speed with Continuous AF mode). Shoot 60 frames per burst, when quality set to ‘FINE’ and image size set to ‘L.’
Quick AF Full HD movie
Shoot 1920x1080 video with full-time AF tracking of moving subjects: now with 60p/24p progressive shooting for cinematic results.
Creative Full HD movie functions
Enjoy sharp, accurate autofocusing with full-time AF; PASM exposure modes offer total creative control.
AF Range Control
Locks autofocusing to a specified range of distance from the camera for sharp results, even if the target is obscured momentarily by another passing object.
Wide sensitivity range from ISO 100-25600
High maximum sensitivity allows natural, low-noise images, even in low light: expansion mode extends sensitivity down to ISO 50.
3-way tiltable LCD screen
Freely-adjustable high resolution (1,228k dot) LCD with WhiteMagic technology for clear viewing, even under direct sunlight.
XGA OLED TruFinder™
Precision electronic viewfinder with high contrast and 100% frame coverage for accurate framing, focusing and shot review.
High-resolution information display
Select from a choice of Graphic Display, Display All Info, No Disp. Info, Histogram or Digital Level Gauge display options.
Clear Image Zoom
Digitally zooms centre portion of image up to 2x with nearly imperceptible degradation, virtually doubling your zooming range.
Face Detection with Face Registration
Recognizes up to 8 faces in a scene, optimizing optimum exposure, white balance, flash and other settings for beautiful portraits.
Expanded Flexible Spot
If the active AF point begins to lose track of your subject, one of 8 surrounding AF points instantly activates for continuous, accurate tracking of your moving subject.
Enhanced AF area modes
Lock-on AF, which optimizes target frame size and ensures use of the optimal AF point, is now available as a focus area mode. You can choose the initial AF point for tracking from the Wide, Zone, Center, Flexible Spot or Expanded Flexible Spot AF area mode.
5-step tracking adjustment
AF tracking duration is adjustable in 5 steps, with low settings prioritizing stability and high settings prioritizing speed (ideal when shooting various subjects at different distances, for example). Three settings are also available when shooting movies.
Eye AF
Captures faces in sharp focus, even when your subject is partially turned away from the camera with a shallow depth of field.
Leading image technologies
Detail reproduction technology minimizes emphasized outlines to produce more realistic images and finer details. Diffraction-reducing technology corrects blurred details to realize finer detail even at small aperture (large F-number) settings.
Area-specific noise reduction
Along with detail reproduction technology, effectively suppresses noise for clearer, more finely detailed images even at high sensitivity settings.
Enhanced in-body image stabilization
Effective image stabilization for any compatible lens, throughout the entire focal length range. Helps stabilize the viewfinder image while the shutter button is halfway pressed.
Focus Magnifier and Peaking function
Magnify your image or movie in the high-resolution viewfinder for manual fine-tuning of the focus, or use Peaking to colorize the most sharply-focused areas of your image for quick confirmation.
Adjustable viewfinder settings
To compensate for the type and amount of light in your surroundings, adjust the viewfinder color temperature and brightness in 5 simple steps.
Customizable function buttons
Assign frequently used functions to the customizable buttons of your choice. Easily reassign 11 buttons to activate any of 53 functions for speedier, more intuitive operation.
