What Common Both Can Do?

  • Camera type: Both models are full-frame mirrorless cameras designed for advanced enthusiasts and professionals. This format allows for high image quality while keeping bodies smaller than traditional DSLRs.
  • Sensor size: Each camera uses a 35mm full-frame sensor, which delivers strong low-light performance and shallow depth-of-field control. This matters for portrait, event, and cinematic-style shooting.
  • Lens mount: Both systems use interchangeable lenses, giving access to extensive native and third-party lens ecosystems. This flexibility allows photographers and videographers to tailor setups to specific shooting needs.
  • In-body image stabilization: Each camera includes sensor-shift stabilization to reduce blur from hand movement. This is especially useful for handheld photography and video in low-light conditions.
  • Autofocus with eye detection: Both cameras support eye-detection autofocus for people. This improves hit rates for portraits and ensures consistent focus on the subject’s eyes.
  • Face detection AF: Face detection is built into both systems to prioritize human subjects automatically. This is valuable for events, interviews, and casual shooting where speed matters.
  • Animal detection AF: Both cameras can recognize animals for autofocus tracking. This helps wildlife and pet photographers maintain sharp focus on unpredictable subjects.
  • Electronic viewfinder: Each model uses an electronic viewfinder rather than an optical one. EVFs provide real-time exposure preview and shooting information before the image is captured.
  • EVF resolution class: Both cameras use a similar high-resolution EVF class around 3.69M dots. This results in clear composition and accurate manual focusing.
  • Vari-angle rear LCD: Fully articulating rear screens are present on both bodies. This design supports shooting from high, low, or front-facing angles for video and vlogging.
  • Touchscreen control: Touch input is available on both cameras for focus selection and menu navigation. This speeds up operation and improves usability in dynamic shooting scenarios.
  • Dual card slots: Each camera includes two memory card slots. This allows for backup recording or separation of photo and video files for safer workflows.
  • UHS-II SD support: Both models support fast UHS-II SD cards. Faster cards reduce buffer clearing times and support high-bitrate video recording.
  • 4K video recording: Both cameras can record 4K video internally. This meets modern resolution standards for professional and enthusiast video production.
  • 10-bit internal video: Each camera supports 10-bit internal recording. This provides greater color depth and flexibility during color grading.
  • Log gamma profiles: Log profiles are included on both models for video. These profiles preserve dynamic range and are important for professional post-production workflows.
  • Microphone input: Both bodies include a dedicated microphone jack. This enables higher-quality audio capture using external microphones.
  • Headphone output: Headphone monitoring is available on both cameras. This allows real-time audio checking during video recording.
  • USB-C connectivity: Each camera uses USB-C for data transfer and power-related functions. This improves compatibility with modern accessories and power solutions.
  • Weather sealing: Both cameras feature weather-resistant construction. This helps protect the camera during outdoor and travel shooting in challenging conditions.
