Sensor and Image Quality
The Nikon D40 boasts a 6.1-megapixel CCD sensor, while the D3100 features a 14.2-megapixel CMOS sensor. CMOS sensors are generally considered more advanced and offer better noise performance in low-light conditions. In terms of image quality, the D3100 has a clear advantage due to its higher resolution and improved sensor technology.
Autofocus System
Both the D40 and D3100 utilize a phase-detection autofocus system, which provides quick and accurate focusing. However, the D3100 features a more advanced 11-point autofocus system compared to the D40’s 3-point system. This allows the D3100 to track moving subjects more effectively and achieve sharper focus, especially in challenging lighting situations.
Continuous Shooting Speed
The D40 offers a continuous shooting speed of 2.5 frames per second (fps), while the D3100 can capture up to 3 fps. While both cameras are suitable for general photography, the D3100’s slightly faster shooting speed can be beneficial for capturing action shots or photographing moving subjects.
