Performance
In real-world use, the Alpha 7 IV exceeded my expectations. The image quality is stunning, with vibrant colours, excellent detail, and impressive dynamic range. Low-light performance is noticeably improved compared to its predecessor. The autofocus is incredibly fast and accurate, even in challenging conditions. I tested it extensively in various situations – from fast-paced sports photography to low-light portraits – and it consistently delivered sharp, well-focused images.
Video recording capabilities are also top-notch. The 4K video footage is crisp and detailed, and the autofocus tracking during video recording is exceptionally smooth and reliable. I found the improved stabilization to be a major asset, allowing for smoother handheld shots.
The camera’s responsiveness is excellent. The menu system, although extensive, is well-organized and easy to navigate once you familiarize yourself with it. The battery life is decent, although it can be improved. The camera does become quite warm during prolonged video recording sessions, however it didn’t affect my usage too much.
Pros & Cons
- Pros: Excellent image quality, fast and accurate autofocus, impressive video capabilities, 5-axis image stabilization, robust build quality.
- Cons: Battery life could be better, the camera does get warm during extended use, some users might find the menu system a bit complex initially.
Final Verdict
The Sony Alpha 7 IV (ILCE-7M4) is a fantastic full-frame mirrorless camera that offers a compelling blend of performance, features, and image quality. While there are a few minor drawbacks like battery life, these are easily outweighed by its strengths. If you’re a serious photographer or videographer looking for a versatile and high-performing camera, the Alpha 7 IV is a strong contender and I highly recommend it.
