Nikon D5300 review

New 24MP sensor and EXPEED 4 processing engine give better images

We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.

A high signal to noise ratio (SNR) indicates a cleaner and better quality image.

For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.

Here we compare the Nikon D5300 with the Nikon D5200, the Sony Alpha 65 and the Canon EOS 700D.

JPEG signal to noise ratio

Nikon D5300 review

The D5300's signal to noise ratio is very respectable throughout the sensitivity range, but it's beaten by the competition at the middle values. This is likely be because it is calibrated to reveal more detail at the expense of a little noise. It takes the lead at the highest settings, however.

TIFF signal to noise ratio

Nikon D5300 review

Apart from at ISO 100, the D5300's raw files after conversion to TIFF are runner's up to the Nikon D200, Sony Alpha 65 and Canon 700D's files, indicating that they are a little noisier. This is the result of the higher pixel count and/or change in the processing to reveal more detail.

JPEG dynamic range

Nikon D5300 review

The D5300's JPEGs have an impressive dynamic range, similar to the D5200's, indicating that they contain a wide range of tones.

TIFF dynamic range

Nikon D5300 review

A camera's raw dynamic range is a measure of its underlying ability to record different brightnesses in the same frame and it is usually higher than the camera's JPEG dynamic range - which is manipulated to give the manufacturer's preferred level of contrast. The D5300's raw (after conversion to TIFF) dynamic range competes well at the lower sensitivity settings, but drops off significantly at the upper values.
