The a7 III shares the same 4K video resolution and dimensions as the a7 IV, making it a viable option for videographers who prioritize video quality but do not need the advanced features of the a7 IV.

Comparing the video capabilities of the Sony a7 III and a7 IV, it is clear that the a7 IV is the superior camera. Its higher video score, faster frame rate, and time-lapse functionality make it a more versatile option for videographers seeking advanced features. The a7 III, while still offering 4K video resolution, lacks these additional capabilities, making it a less appealing choice for those prioritizing video performance.

The Sony a7 IV wins the feature comparison with a score of 83/100, while the Sony a7 III scores 81/100. Both cameras share several specifications, including a 3-inch screen size, touchscreen capabilities, flip screen, and the absence of GPS.

This higher resolution provides a clearer and more detailed image preview and playback experience for the user. The two-point difference in the feature score reflects this advantage of the a7 IV over its counterpart.

Despite the Sony a7 III’s lower score, it still holds its own as a reliable camera with its shared features, such as the flip screen and connectivity options. However, the a7 III does not outperform the a7 IV in any specific aspect based on the given specifications.

Taking into account the shared features and the a7 IV’s superior screen resolution, the Sony a7 IV emerges as the better option between the two cameras. The a7 III remains a decent choice for those who prioritize other aspects or are on a tighter budget. Ultimately, the choice between these two cameras depends on the user’s preferences and needs.

Both cameras share common features such as two memory card slots and the NP-FZ100 battery type.

The a7 IV surpasses the a7 III in storage capabilities by accepting CFexpress Type A and UHS-II compatible SD cards, offering faster read and write speeds. Both have USB charging, allowing for convenient charging options and extended usage.

On the other hand, the a7 III has a longer battery life with 750 shots compared to the a7 IV’s 580 shots. However, this advantage may not fully compensate for the a7 IV’s superior storage and charging options.

Considering these factors, the Sony a7 IV proves to be a better choice in terms of storage and battery performance, while the a7 III offers a slightly longer battery life.
