Image Quality
The Sony A7III boasts a full-frame 24.2MP Exmor R CMOS sensor, while the Nikon D5100 features an APS-C 16.2MP CMOS sensor. The larger sensor size of the A7III provides several advantages, including better low-light performance, reduced noise, and a wider dynamic range. As a result, the A7III produces images with superior detail, color accuracy, and overall image quality.
Autofocus and Speed
The Sony A7III is equipped with a hybrid autofocus system that combines 693 phase-detection points with 425 contrast-detection points. This advanced system provides fast and accurate autofocus, even in low-light conditions. In contrast, the Nikon D5100 has a 39-point phase-detection autofocus system, which is less sophisticated and slower.
In terms of speed, the A7III has a maximum burst rate of 10fps, while the D5100 can shoot at up to 4fps. This makes the A7III a better choice for capturing fast-moving subjects or sports photography.
Lens Selection
The Sony A7III is compatible with Sony’s full-frame E-mount lenses, which offer a wide range of options from both Sony and third-party manufacturers. The Nikon D5100, on the other hand, uses Nikon’s APS-C F-mount lenses, which have a narrower selection. Additionally, the A7III can use adapted lenses from other manufacturers, such as Canon EF lenses, with an adapter.
Video Capabilities
The Sony A7III is a formidable video camera, capable of shooting 4K video at up to 30fps and Full HD at up to 120fps. It also supports S-Log profiles and has a built-in microphone input. The Nikon D5100, while capable of recording video, is limited to Full HD at 30fps and lacks advanced video features.
Ergonomics and Handling
The Sony A7III is a larger and heavier camera than the Nikon D5100, but it also offers better ergonomics. The A7III has a comfortable grip, well-placed controls, and a customizable menu system. The D5100, while smaller and lighter, has a more compact design and may not be as comfortable for extended use.
