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 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
These results show that the Panasonic TZ60 JPEG files have a strong signal to noise ratio indicating that its images are fairly clean at the low to mid sensitivity settings. It improves on the performance of theTZ40 and compares well against the Olympus Stylus SH-50 and Canon S120, although the Canon S120 beats the competition for much of its upper sensitivity range.
Raw signal to noise ratio
The signal to noise ratios of the TIFF images (after conversion from raw) from the Panasonic TZ60 beat the Canon PowerShot S120. These results show that while noise is apparent above ISO 800 it is well controlled.
JPEG dynamic range
JPEG results for dynamic range compare well against the Canon PowerShot S120, Panasonic TZ40 andOlympus Stylus SH-50, although the Canon S120 beats the competition by around 0.5EV at some of the higher sensitivity settings. The graph shows that while results are close at ISO 400 and 1600, the TZ-60 beat the TZ-40 at all other sensitivities.
Across the complete sensitivity range the Panasonic TZ60 beats the Canon PowerShot S120, with the gap between the two extending dramatically above ISO 800.
