Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test.
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.
JPEG signal to noise ratio
Analysis: The SX700 produces a pretty typical performance for this type of camera though the SX280 does prove slightly better at higher ISOs.
JPEG dynamic range
Analysis: The SX700 proves the best overall performer in this group, capturing a slightly wider range of brightness values than its rivals.
