Sony A7III vs A7C

Sony a7c vs a7iii – Check Which One Is Better & Why?

Camera, Sony

Both cameras are part of Sony’s full-frame mirrorless lineup, and both are compact & high-performance Camera, but they do have some differences. If you want the best one between them, I Would recommend the Sony A7III rather than Sony a7c.

Why Do I Recommend Sony A7 III?

  • Sony a7III Comes with a slightly larger 0.5-inch viewfinder and a tilting touchscreen LCD, offering a potentially better viewing experience for stills photography, but Sony a7C Features a smaller 0.39-inch viewfinder and a vari-angle touchscreen LCD.
  • The maximum shutter speed of the Sony A7III is 1/8000 sec, which helps capture super-fast moving objects without blurring, like racing cars or bikes. The Sony A7C has a maximum shutter speed of 1/4000 sec.
  • It has Dual SD card slots, offering more flexibility for backup, extended storage, or separate file management on the go. Sony a7C has a Single SD card slot, which might be a limitation for professional work that requires instant backup or extensive shooting without changing cards.
  • Both cameras offer microphone and headphone jacks, but the handling noise and the practicality of using these inputs might differ due to the body design and layout of each camera. The a7C’s smaller body might be more prone to picking up handling noise when using on-camera microphones.
  • Sony a7III Includes a flash sync port for connecting to studio lighting, a feature that’s absent in the a7C. This could be an important consideration for photographers who frequently work in a studio setting.
  • It offers better control options, including dedicated dials and a joystick for AF point selection, providing a more tactile and immediate control experience, particularly appreciated by professionals and advanced users, but Sony a7C’s compact body has less space for direct control dials & buttons, which can affect how quickly and easily some users might adjust settings.

Maybe the Sony A7c price can make you comfortable because it’s a little bit cheaper than the Sony A7iii. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
