The Nikon D3100 receives a score of 41/100. Launched in October 2010, this DSLR camera initially sold for $699. Measuring 124 x 96 x 75mm and weighing 505g or 1.11lbs, the D3100 is a compact and lightweight option. However, considering the advancements in camera technology since its release, the D3100 may not be the most competitive choice in today’s market. Despite this, it remains a viable option for beginners or those looking for an affordable DSLR camera.

Nikon D3100 Overview and Optics

The Nikon D3100’s optics receive a score of 41 out of 100. With 14.8 megapixels, a shooting speed of 3 frames per second, and a CMOS sensor, the camera provides decent image quality. The Expeed 2 processor and DXOMARK sensor score of 67 contribute to its overall performance. However, the APS-C sensor size and Nikon F DX lens mount are standard features found in similar cameras on the market.

The absence of image stabilization may result in less sharp images when shooting handheld, and the 3:2 aspect ratio is a common format for most DSLRs. Comparing these specifications to other cameras available today, the Nikon D3100 falls short of providing cutting-edge technology or exceptional performance in the optics department.

The Nikon D3100 is a reliable option for beginner photographers, but those seeking advanced features and superior optics may want to explore other cameras in the market.

Nikon D3100 Storage and Battery

The Nikon D3100 receives a storage and battery score of 53/100. This camera has a single memory card slot, compatible with SD, SDHC, and SDXC cards.

The battery life offers an impressive 4500 shots per charge, utilizing the EN-EL14 battery type. This surpasses many competitors, providing extended shooting time for users. Unfortunately, the camera lacks USB charging capabilities, which limits convenience compared to modern cameras with this feature.

Considering these specifications, the Nikon D3100 has a decent storage and battery performance, yet falls short in some aspects when compared to current market standards.
