What is the difference between the Sony A7 III and A7 IV?

Are you torn between the Sony A7 III and the Sony A7 IV? That’s understandable. Both full-frame system cameras are extremely popular among photographers and videographers, but there are clear differences that can make a big impact on your work or hobby.

What are the biggest differences between the Sony A7 III and the Sony A7 IV?

Although the Sony A7 III and A7 IV look very similar in terms of design, there are important technical and functional differences that can influence your choice. Both models feature a full-frame sensor and are aimed at hybrid photographers, but in many ways, the A7 IV is a clear step forward.

The Sony A7 IV offers a higher resolution of 33 megapixels, delivering more detail when editing or printing photos. There are also major improvements in video capabilities: 4K 60p recording in 10-bit 4:2:2 provides much more flexibility for color grading and editing. The addition of Eye AF during video recording makes the A7 IV especially appealing for content creators and vloggers.

In terms of usability, the A7 IV features a fully articulating screen instead of the tilting screen found on the A7 III. In addition, the electronic viewfinder has a higher resolution, resulting in a sharper and more comfortable viewing experience. The autofocus system has also been refined with more focus points and faster subject tracking.

However, the Sony A7 III remains an excellent choice for those who primarily focus on photography or work with a more limited budget. The image quality is still impressive, and for users who do not need advanced video features, it remains a powerful and reliable all-round camera.
