The Nikon D7100 clearly outperforms the Nikon D90 with a score of 65/100 compared to 44/100. Both cameras are DSLRs and share some common specifications, such as their similar size and weight, with the D7100 measuring 136 x 107 x 76mm and weighing 1.69lbs, while the D90 measures 132 x 103 x 77mm and weighs 1.55lbs.

The D7100 has the advantage of being a more recent model, released in 2013, and originally priced at $1200. This newer technology contributes to its higher score. On the other hand, the D90, released in 2008 with a launch price of $1235, is a slightly older model, which may explain its lower score.

Despite the age difference, both cameras have their own merits. The D7100’s improved technology results in better performance, while the D90’s slightly smaller size and lighter weight offer a more compact option for photographers. Ultimately, the choice between the two depends on the individual’s preferences and priorities.

Nikon D7100 vs D90 Overview and Optics

The Nikon D7100 emerges as the winner in the optics comparison with a score of 67/100, outperforming the Nikon D90, which scored 46/100. Both cameras share some common specifications, including the CMOS sensor type, APS-C sensor size, Nikon F DX lens mount, and the lack of image stabilization.

The D7100 excels with its higher megapixel count of 24.1 compared to the D90’s 12.3, allowing for greater image resolution and detail. Additionally, the D7100’s shooting speed of 6 frames per second surpasses the D90’s 4.5, providing faster capture of action shots. The D7100 also benefits from an improved Expeed 3 processor, which enhances image processing and overall performance. Its DXOMARK sensor score of 83 further highlights the superiority of the D7100’s sensor quality over the D90’s score of 73.

On the other hand, the Nikon D90 holds its ground with its lower price point and simpler interface, which may be more suitable for beginner photographers. However, its lower specifications in megapixels, shooting speed, and sensor quality make it less competitive compared to the D7100.

Taking all factors into account, the Nikon D7100 stands out as the better camera in terms of optics, offering higher image resolution, faster shooting speed, and an overall better sensor. While the Nikon D90 may still appeal to those on a budget or seeking a more straightforward camera, the D7100’s superior specifications make it the clear winner in this comparison.
