About This CameraThe Sony a7C is a compact full-frame mirrorless camera released in 2020. It measures 124 x 71 x 60 mm and weighs 509 g, fitting a full-frame sensor into a small, light body. That combination suits travel, street and everyday photographers who want a big sensor without carrying a bulky kit. The electronic viewfinder offers 2,360,000 dots for framing, and the 3-inch touchscreen handles settings. Wi-Fi and Bluetooth are built in, and the camera uses the Sony FE lens mount. There is no built-in flash, though external flash units are supported. | |

Optics80/100 | |
About the OpticsThe 24.2 megapixel full-frame sensor is the heart of this camera. It scores 80 out of 100 for Optics, a very good result that places it in the top 8% of cameras in our database, and the resolution leaves room for large prints and generous cropping. Autofocus offers 693 points, giving many selectable positions for focusing. The camera also shoots at up to 10 fps in burst mode, though that figure is a maximum; sustained rates will depend on settings and conditions. In-body image stabilisation reduces camera shake, making handheld shooting at slower shutter speeds more practical. It steadies your hands, not the subject, so moving subjects still need faster shutter speeds of their own. The ISO range runs from 100 to 51200. The 1/4000 s maximum shutter speed is the main constraint: in strong light you may need to stop down or use a neutral density filter to shoot wide open. | |
Megapixels ⓘThe higher the number of megapixels, the more detail the cameras sensor can capture. | 24.2 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. | 23.8 x 35.6 |
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. | 10 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 FE |
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. | 512003003280000 |
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. | 2048003003280000 |
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. | 400080032000 |
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. | 6930300 |
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 |

Video70/100 | |
About the VideoVideo is well covered for standard projects. The camera records in 4K video, which leaves room to crop and reframe in editing. It scores 70 out of 100 for Video, a good rating based on its maximum resolution, maximum frame rate and built-in timelapse mode. The maximum frame rate is 30 fps. That handles natural motion for travel, event and interview work, but it limits the slow-motion look that some action and creative footage calls for. Footage records in the XAVC S format. A built-in timelapse mode adds a frame-by-frame option without needing extra accessories. In-body stabilisation also helps keep handheld clips steadier, since it counters camera shake rather than subject movement. | |
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. | 3840 x 2160 |
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. | 30 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. | |
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. | XAVC S |
Features81/100 | |
About the FeaturesThe features score of 81 is very good, with full points for the touchscreen, weather sealing, live view and Bluetooth. The 3-inch screen has 921,600 dots, so menus and focus points stay readable. It also flips out, which helps with overhead shots, waist-level work and framing yourself. Weather sealing helps protect the body against dust and moisture. On a camera this small, it is a practical safeguard for outdoor work in dusty or drizzly conditions. Wi-Fi and Bluetooth are built in. There is no GPS, so files will not be tagged with locations automatically. There is also no built-in flash, though external flash units are supported when you need extra light. | |
Builtin flash ⓘA built-in flash will often be positioned right above the lens. This will automatically pop up when you activate it. | No |
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 | LCD |
Touch screen ⓘTouchscreen allows you to change camera settings and access menus with a swipe of your finger, instead of using buttons. | |
| Screen size | 3" |
Screen dots ⓘScreen dots indicate the resolution of the LCD screen by including each sub pixel. | 9216001150001500000 |
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. | |
Bluetooth ⓘBluetooth capabilities allow you wireless control of your camera with other external devices. | |
Storage & Battery45/100 | |
About the Storage & BatteryThe storage and battery score of 45 is modest, and the single card slot is the main reason. That one SD slot accepts SD, SDHC and SDXC cards and is UHS-II compatible. Without a second slot there is no in-camera backup, which matters when a shoot cannot be repeated. The NP-FZ100 battery is rated at 740 shots. Treat that as a rating rather than a promise of real-world endurance, since actual results depend on how you shoot. USB charging is supported, so you can top the camera up between shoots without the mains charger. It is a convenient backup option, but it does not remove the need to plan power around a full day of shooting. | |
