About This CameraThe Sony SLT Alpha 77 II is a DSLR camera from 2014 built around an APS-C sensor and the Sony Alpha DT lens mount. Its defining strengths are 24.3-megapixel resolution, a 12fps maximum burst rate and in-body stabilisation, a combination suited to action and handheld work. The body is fairly substantial at 143 x 104 x 81mm and 647g, so it handles like a full DSLR rather than a compact travel option. An electronic viewfinder and live view both show the scene as the sensor captures it. Wi-Fi is built in for wireless use, and weather sealing makes outdoor shoots less of a worry. | |

Optics74/100 | |
About the OpticsA 24.3-megapixel APS-C CMOS sensor, handled by the Bionz X processor, gives plenty of resolution for large prints and generous cropping. The Optics score of 74 reflects a genuinely good stills package, and the camera sits in the top 17% of cameras in our database for Optics. For moving subjects, the 12fps maximum burst rate is generous, though as a maximum it depends on conditions rather than promising a sustained rate. A 1/8000s top shutter speed helps when you want wide apertures in bright light. In-body stabilisation reduces camera shake with any mounted lens, steadying handheld shots at slower shutter speeds. It counters your own movement, not a moving subject's, so it complements fast shutter speeds rather than replacing them. Seventy-nine autofocus points are available, and the 2.36-million-dot electronic viewfinder previews exposure in detail. The ISO range runs from 100 to 25600, which covers everyday conditions. | |
Megapixels ⓘThe higher the number of megapixels, the more detail the cameras sensor can capture. | 24.3 MP050 |
Image resolution ⓘImage resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 6000 x 4000 |
Sensor type ⓘThe camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality. | CMOS |
Sensor size ⓘThe sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture. | 15.6 x 23.5 |
Sensor format ⓘRefers to the most commonly used sensor sizes. | |
Continuous shooting ⓘThe number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode. | 12 fps045 |
Lens mount ⓘThe lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras. | Sony Alpha DT |
Image processor ⓘThe image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Bionz X |
Aspect ratio ⓘThe aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3. | |
Min ISO ⓘRefers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 10030200 |
Max ISO ⓘRefers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 256003003280000 |
Min ISO (expanded) ⓘExpanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 5030200 |
Max ISO (expanded) ⓘExpanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 512003003280000 |
Minimum shutter speed ⓘThe minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 3044080 |
Max shutter speed ⓘThe maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 800080032000 |
Autofocus points ⓘAutofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 790300 |
In-body stabilisation ⓘIn-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. | |
Viewfinder type ⓘThe viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Electronic |

Video56/100 | |
About the VideoVideo is supported, with a maximum resolution of Full HD. That ceiling shapes the experience: footage suits web use and HD viewing, but there is no 4K option. The modest Video score of 56 reflects the Full HD resolution limit, the frame-rate maximum and the missing built-in timelapse mode. The maximum frame rate is 60fps. That figure and the resolution maximum are separate limits, so the two do not necessarily combine. Recordings save as AVCHD or MP4 files. There is no built-in timelapse feature, so the camera itself does not automate interval recording. The flipping screen helps with framing at waist or overhead height while filming, and the electronic viewfinder provides an alternative for handheld shooting. | |
Video ⓘIndicates if this camera is capable of recording video. | |
Max video resolution ⓘThe best resolution this camera can capture video in. Modern cameras can capture up to 8K video. | |
Max video format ⓘVideo resolution measured by the greatest number of pixels possible in each frame, width by height. A higher resolution means more detail or clarity in your video. | 1920 x 1080 |
Max video frame rate ⓘHow many frames per second your video will capture. Most cameras have options for multiple frame rates, depending on the resolution you shoot in. For a general video, 24p or 30p is the standard, but more serious filmmakers may need a higher frame rate for creative effect. | 60 fps |
Timelapse built in ⓘA built in time-lapse mode will allow continuous shooting throughout a prolonged period of time to be compressed into a sped up video. | No |
Video file format ⓘDifferent cameras can record in various video file formats. The File format you record in can impact how you edit and use the files. | AVCHD, MP4 |
Features57/100 | |
About the FeaturesThe 3-inch TFT screen carries 1.23 million dots, which keeps composition and image review detailed. It flips out, so waist-level and overhead shots are much easier to frame. There is no touchscreen, though, so settings change through the physical controls. Wi-Fi is built in, but there is no Bluetooth and no GPS, so the body does not tag locations on its own. Live view rounds out the composition options when the viewfinder is impractical. A built-in flash handles occasional fill light, and the external flash shoe accepts more powerful units. Weather sealing helps the body cope with dust and moisture outdoors. The modest Features score of 57 reflects the absent touchscreen and Bluetooth, with the screen and live view counting in its favour. | |
Builtin flash ⓘA built-in flash will often be positioned right above the lens. This will automatically pop up when you activate it. | |
External flash ⓘExternal flashes are often connected through a hot shoe at the top of a camera, or a cable at the side of the camera. | |
GPS ⓘGPS features in a camera will include location metadata to each of your photographs. | No |
Weather sealing ⓘWeather sealing capabilities will give you more confidence when shooting in unfavourable conditions. | |
| Screen type | TFT LCD |
Touch screen ⓘTouchscreen allows you to change camera settings and access menus with a swipe of your finger, instead of using buttons. | No |
| Screen size | 3" |
Screen dots ⓘScreen dots indicate the resolution of the LCD screen by including each sub pixel. | 12290001150001500000 |
Flip screen ⓘA flip screen (or articulating screen) is a second screen which can flip out from the side or top of the camera. This rotating screen allows you more freedom to take photos at different angles. | |
Live view ⓘLive View feature allows you to see a continuous live video of what is being seen through your lens. | |
Wi-Fi ⓘBuilt-in Wi-Fi allows you to connect your camera and share images wirelessly. | |

Storage & Battery27/100 | |
About the Storage & BatteryStorage runs through a single slot that accepts SD, SDHC and SDXC cards as well as Memory Stick Pro Duo and Pro-HG Duo media. With no second slot, a full card means a pause, and there is no way to record to two cards at once. The NP-FM500H battery is rated at 480 shots. Treat that as a baseline for planning rather than a promise for every shoot; a spare battery covers long days. USB charging is absent, so the battery charges in its charger rather than from a computer or power bank. The limited Storage & Battery score of 27 comes mainly from these three gaps: one slot, moderate endurance and no USB charging. | |
