Video Capabilities

Both cameras offer impressive video recording capabilities, with the Canon EOS 90D shooting 4K video at 30fps and the Sony Alpha 7C offering 4K video at 30fps and 24fps. However, the Sony Alpha 7C has the edge in video features, including internal 4K recording up to 10-bit 4:2:2, S-Log2/S-Log3 profiles, and Hybrid Log-Gamma (HLG) for HDR video recording.
Canon EOS 90D:

• 4K Video at 30fps: The EOS 90D captures high-quality 4K video, but lacks the advanced features found in the Alpha 7C.
• Internal 4K Recording: The camera records 4K video internally, eliminating the need for an external recorder.

Sony Alpha 7C:

• 4K Video at 30fps and 24fps: The Alpha 7C offers various frame rates for 4K video recording, including 24fps for cinematic looks.
• Advanced Video Features: The Alpha 7C features internal 10-bit 4:2:2 recording, S-Log profiles, and HLG for HDR video, providing greater flexibility for post-production.

Design and Ergonomics

The Canon EOS 90D and the Sony Alpha 7C offer different design philosophies. The Canon EOS 90D is a traditional DSLR with a deep grip and a dedicated viewfinder, making it comfortable to hold and use.

Answers to Your Questions

Q: What is the difference between APS-C and full-frame sensors?
A: APS-C sensors are smaller than full-frame sensors, resulting in a crop factor of 1.6x. This means that the lens’s focal length is effectively multiplied by 1.6, providing a wider field of view. Full-frame sensors offer a larger surface area for capturing light, resulting in better low-light performance and shallower depth of field.
Q: What is the benefit of a hybrid viewfinder?
A: A hybrid viewfinder combines an electronic viewfinder (EVF) with an optical viewfinder (OVF). This allows you to switch between the two depending on your needs. The EVF provides a live preview of the image with exposure settings, while the OVF offers a traditional view with a brighter and more natural image.
Q: What is S-Log and why is it important for video?
A: S-Log is a gamma curve setting that captures a wider dynamic range, providing more flexibility for grading and color correction in post-production. It allows you to capture more detail in highlights and shadows, resulting in a more cinematic look.
Q: What is the difference between Wi-Fi and Bluetooth connectivity?
A: Wi-Fi allows for faster data transfer and remote control of the camera from a smartphone or tablet. Bluetooth provides a low-power connection for pairing with devices and transferring basic information, such as GPS data.
Q: What is the difference between 4K 30fps and 4K 24fps video?
A: 4K 30fps video captures 30 frames per second, resulting in smooth and natural motion. 4K 24fps video captures 24 frames per second, which is the standard frame rate for film and creates a more cinematic look.
