The Sony α7C is a relatively compact full-frame camera. It's a mirrorless interchangeable lens model with a lightweight design that's not much bigger than the crop-sensor Sony α6600. JPEG image quality is fantastic, and it has remarkable RAW noise handling capability, making it well-suited to low light photography. Its video quality is excellent in both 4k and 1080p, and it has an amazing autofocus system with advanced real-time tracking that does an exceptional job tracking moving subjects when recording video. The camera feels incredibly well-built, and unlike the Sony α7 III, it has a fully articulated screen to help you shoot from different angles. It also has an exceptional battery life that should last through long days of shooting. However, it's not the most comfortable camera, as Sony compromised a bit on ergonomic features to achieve its compact form factor by having fewer dedicated dials and buttons and a less comfortable viewfinder than some of its Alpha series counterparts.
The Sony a7C is great for travel photography. It's fairly lightweight and portable, especially considering it has a full-frame sensor. It captures incredibly high-quality images and performs well even in low light, and it has an exceptional battery life that should last through long days on the go. It also has an excellent autofocus system that reliably keeps moving subjects in focus. That said, it's not the most comfortable to use since its size and design can make for a somewhat cramped handgrip when coupled with larger lenses, especially if you have larger hands. Its menu system can also be a bit cumbersome to navigate.
The Sony a7C is an impressive camera for landscape photography. Its image quality and RAW noise handling capability are remarkable, and it has excellent dynamic range to bring out a wide array of detail in high-contrast landscape shots. It's also weather-sealed to protect against rain and humidity, though we don't currently test this. All in all, the camera feels incredibly well-built and is very portable for a full-frame camera, but its design leaves less room for a comfortable handgrip, especially for those with larger hands.
The Sony a7C is very good for sport and wildlife photography. It delivers remarkably high-quality images with minimal visual noise even at higher ISO levels. It also has a fast max shutter speed and a good continuous shooting speed, although its buffer emptying time may interrupt your shooting if you manage to fill the buffer. Its autofocus system is excellent and does a particularly superb job tracking moving objects. It also has both human and animal eye-tracking settings, which are great for photographing athletes or wildlife, respectively.
The Sony a7C is very good for vlogging. It's relatively compact and portable for a full-frame camera, and it has a fully articulated screen so you can monitor yourself while recording. It has in-body image stabilization, which is great, but the camera doesn't do a good job smoothing out camera shake when moving at a moderate pace. On the upside, it has an exceptional autofocus system that ensures your face stays in focus, and its overall video quality is excellent. There's no recording time limit, either, and its battery life is fantastic, with no instances of overheating during testing.
The Sony a7C is excellent for studio video. Its video quality is impressive, whether shooting in 4k or 1080p, and it has good internal recording capability, though its recording format options are a bit limited, and its menu system can be hard to navigate. It supports several S-Log and HLG log picture profiles for more in-depth color grading in post. Its battery life is also exceptional, and it doesn't have a recording time limit and shouldn't overheat, though this can vary in real-world conditions. You can also keep using it while its charges via USB. It comes with a full array of inputs and outputs, including a headphone jack and stereo microphone input, and a micro HDMI port with clean HDMI output so you can use an external recorder without overlays. It only has one SD card slot, which may disappoint more serious videographers.
The Sony a7C is a mediocre choice for action video, though it's not meant for this use. While it's compact relative to other full-frame mirrorless cameras, it's not designed to be mounted on a helmet or other action video rigs. It's weather-sealed but not fully waterproof, although we don't currently test for this. Unlike many models, it can record and playback FHD video at up to 120 fps, which is good for generating slow-motion footage, but its 4k frame rate options are more limited.
Note: This camera has extended low ISOs of 50, 64, and 80. Its extended high ISOs are 64,000, 80,000, 102,400, 128,000, 160,000, and 204,800.
Note: The Sony Alpha 7C has an 'APS-C/Super 35mm' mode that allows it to adapt its sensor to compatible APS-C lenses.
Note: While the max shutter speed is 1/4000s when using the mechanical shutter, this camera's electronic shutter speed goes up to 1/8000s.
Note: The Sony Alpha 7C is advertised to have 693 phase-detection autofocus points when using a full-frame lens, 299 phase-detection AF points when using a full-frame lens in APS-C mode, and 221 phase-detection AF points when using an APS-C lens in APS-C mode. It also has 425 contrast-detection AF points.
Note: We conducted this test at a 60mm focal length instead of the usual 70mm we usually use because the kit lens has a max focal length of 60mm. For that reason, the results may not be fully comparable with other cameras we've tested.
The Sony a7C comes in two color variants: 'Black' and 'Silver'. We tested the 'Black' model with the Sony FE 28–60 mm F4–5.6 kit lens, though you can also buy it in either color without a lens.
