Sony A7R Mark IV body, where R stands for resolution in Sony.

The Sony A7R Mark IV A has a resolution of 61 megapixels. In addition, it features a well-developed 35mm CMOS sensor and a powerful BIONZ X processor. Both ensure that you benefit from high resolution, low noise, 15-stop dynamic range, and high ISO sensitivity. The default value is 100-32000, but it is expandable to 50-102,400.

5-axis image stabilization is achieved by an algorithm that communicates with the FE lens. This is not only interesting for photographers but also for videographers. Your images will be stable and sharp. Furthermore, with a mirrorless camera, you don't have the problem of the noisy flip-up mirror. This allows for silent shooting, which benefits the spontaneity of your photos. People and animals will no longer be startled if you want to take a picture of them.

The difference between the Sony A7R IV and the Sony A7R IV A is the adjustable screen on the camera. While the Sony A7R Mark IV uses 1,440,000 pixels, the A version has been updated to 2,359,296 million pixels. This is a significant improvement, allowing you to achieve more sharpness and see more details and colors. In addition, the LCD screen allows you to quickly and easily navigate through the menu and adjust the focus.

The Sony A7R Mark IV A is suitable for filmmakers if you are looking for a more manageable model. In addition to the option to film in 4K across the full width of the sensor, you can use S-Log2 and S-Log3. These image profiles are renowned for their wide dynamic range of up to 15 stops. This gives you full control over your images during post-processing. Hybrid Log-Gamma (HLG) is also available on the A7R IV to support an Instant HDR workflow. Additionally, you can use the ECM-B1M shotgun microphone or the XLR adapter kit (sold separately) during recording to capture high-quality audio with minimal quality loss.

Sony's autofocus is a highly appreciated feature. Not only is it precise thanks to its 567 focus points, but it is also easy to adjust while shooting with a single tap on the screen. In addition, you have real-time Eye AF. This autofocus finds and tracks the eyes of humans and animals, even when they are moving. Never again a blurry image or a missed moment.

If you are a professional, you will also appreciate the battery life and the speed of storing photographic or cinematic material. Sony uses an NP-FZ100 battery. It has a large capacity that allows you to shoot for an extended period. Furthermore, you will want your images to be stored correctly and preferably as quickly as possible. For this, the Sony A7R IV A uses two media slots for SD cards. So you can use two UHS-I or UHS-II cards. The card slots are located behind a sliding lock cover, so they are protected from external influences and the cover does not open accidentally. This is to ensure not only a technically sound camera inside but also a well-protective casing. That's why Sony chose to equip the camera with a durable and improved housing, resistant to dust and moisture.

The camera is built with an extremely light and strong magnesium alloy and also features an improved extra rigid lens mount. With extra sealing on all camera joints, the battery compartment, and media slots, you can be sure of getting the best photos in all weather conditions with this camera.
