The Nikon D3100 and D90 are two popular DSLR cameras that offer distinct features and capabilities. In this comprehensive comparison, we will delve into the key differences between these two models, helping you make an informed decision based on your photography needs and budget.
Image Quality and Resolution
The Nikon D3100 features a 14.2-megapixel APS-C CMOS sensor, while the D90 has a 12.3-megapixel APS-C CMOS sensor. Despite the higher megapixel count, the D3100’s sensor is slightly smaller than the D90’s, resulting in a slightly lower pixel density. In practical terms, this difference in resolution is not significant and both cameras produce high-quality images.
ISO Performance
The D90 offers a wider ISO range than the D3100, with a native ISO range of 200-3200 (expandable to 6400) compared to the D3100’s native ISO range of 100-3200. This extended ISO range allows the D90 to capture images in low-light conditions without introducing excessive noise.
Continuous Shooting
The Nikon D90 boasts a faster continuous shooting speed than the D3100, capable of capturing up to 4.5 frames per second (fps) compared to the D3100’s 3 fps. This faster shooting speed is beneficial for capturing fast-moving subjects or sequences of action.
Autofocus System
The D90 has a more advanced autofocus system than the D3100, featuring 11 autofocus points (9 cross-type) compared to the D3100’s 11 autofocus points (all single-type). The D90’s more sophisticated autofocus system provides improved accuracy and speed, especially in low-light conditions.
LCD Screen and Viewfinder
Both cameras have a 3-inch LCD screen with a resolution of 230,000 dots. However, the D90’s LCD screen is articulated, allowing it to be tilted and adjusted for more comfortable viewing from different angles. The D90 also has a larger and brighter viewfinder than the D3100, providing a more immersive shooting experience.
Video Recording
The Nikon D3100 was one of the first DSLR cameras to offer video recording capabilities, while the D90 does not support video recording. The D3100 can record 720p HD video at 24 fps, which is sufficient for basic video needs.
Battery Life
The D90 has a longer battery life than the D3100, with a CIPA-rated battery life of 850 shots compared to the D3100’s 550 shots. This extended battery life makes the D90 a more suitable choice for extended shooting sessions.
Price and Availability
The Nikon D3100 is typically available for a lower price than the D90, as it is an older model. The D3100 is still widely available new and used, while the D90 is primarily available on the used market.
Which Camera is Right for You?
The Nikon D3100 is a great option for beginners who are looking for an affordable and easy-to-use DSLR camera. It offers solid image quality, a good ISO range, and a basic video recording capability. However, if you need faster continuous shooting, a more advanced autofocus system, an articulated LCD screen, and a longer battery life, the Nikon D90 is the better choice.
The Bottom Line: The Best Choice for Your Needs
Whether you choose the Nikon D3100 or D90 depends on your specific photography needs and budget. If you are a beginner or occasional photographer, the D3100 offers a great balance of features and affordability. If you are a more experienced photographer or need more advanced capabilities, the D90 is the better choice.
