We will explore the key differences between these two models, including their specifications, features, and performance. Whether you’re a professional photographer or an enthusiast looking for a new camera, this comparison will help you make an informed decision.

What are the main differences in sensor resolution?

The Sony A7R IV features a high-resolution 61-megapixel full-frame sensor, making it ideal for capturing extremely detailed images. On the other hand, the A7 IV has a lower-resolution 33-megapixel full-frame sensor, which still provides excellent image quality but with smaller file sizes.

While the A7R IV is better suited for landscape, architecture, and studio photography where maximum detail is essential, the A7 IV offers a good balance of resolution and performance for a wider range of shooting scenarios.

How do they compare in terms of autofocus performance?

Both cameras are equipped with advanced autofocus systems, but there are some differences in their capabilities. The A7R IV features a 567-point phase-detection autofocus system with Real-time Eye AF for both humans and animals, offering exceptional accuracy and tracking performance.

On the other hand, the A7 IV has a 693-point phase-detection autofocus system with Real-time Eye AF for humans, but it does not include animal eye detection. While the A7 IV still offers impressive autofocus performance, the A7R IV may be the better choice for capturing fast-moving subjects, such as wildlife or sports photography.

What about video recording capabilities?

Both cameras are capable of recording high-quality 4K video, but there are differences in their video features. The A7R IV offers advanced video recording options, including 4K recording at up to 30fps with full pixel readout and no pixel binning, as well as S-Log2 and S-Log3 for greater dynamic range.

On the other hand, the A7 IV also provides 4K video recording at up to 30fps, but it does not offer the same level of advanced video features as the A7R IV. However, the A7 IV does have the advantage of a vari-angle touchscreen, making it more versatile for capturing videos from different angles.

How do they compare in terms of body design and handling?

The A7R IV features a robust, weather-sealed magnesium alloy body with a high-resolution electronic viewfinder and a tilting LCD screen. It also has a dual UHS-II SD card slots for extended shooting capacity. The A7 IV has a similar build quality and weather-sealing, but it features a more compact and lighter body, making it more portable for on-the-go shooting.

Both cameras have a comfortable grip and intuitive control layout, but the A7 IV includes a larger and more user-friendly touchscreen for easier menu navigation and focus control. Ultimately, the choice between the two will depend on your specific shooting needs and preferences in terms of body size and handling.

Which camera is better suited for my needs?

If you prioritize maximum resolution and image detail, as well as advanced video features, the Sony A7R IV may be the better option for your photography and videography needs. It’s an excellent choice for landscape, studio, and commercial photography, as well as professional videography.

On the other hand, if you require a more versatile and compact camera with a good balance of resolution, performance, and handling, the Sony A7 IV offers a compelling package for a wider range of photographers and videographers. Its smaller size, improved autofocus, and vari-angle touchscreen make it well-suited for travel, street, and documentary photography, as well as casual videography.


Both the Sony A7R IV and A7 IV are highly capable cameras with their own strengths and weaknesses. The A7R IV excels in high-resolution imaging and advanced video recording, making it a top choice for professional photographers and videographers. On the other hand, the A7 IV offers a more balanced approach with a compact and versatile design, making it suitable for a wider range of shooting scenarios. Ultimately, the decision between these two cameras will depend on your specific needs and preferences as a photographer or videographer.

2. Which camera offers better low-light performance?

While both cameras feature excellent low-light performance, the A7 IV’s lower-resolution sensor may have a slight advantage in high ISO performance. However, the differences in low-light performance between the two cameras are minimal, and either model is capable of capturing stunning images in challenging lighting conditions.

3. Is the A7R IV significantly heavier than the A7 IV?
