Why you can trust TechRadar
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 images from the Panasonic GF5 show good results for signal to noise ratio at the lower end of the sensitivity scale showing an improvement over the GF3, however as the sensitivity increases noise becomes more of an issue only beating the Nikon 1 J1.
Raw signal to noise ratio
TIFF images (After conversion from raw) show a close comparison to the Panasonic GF3 and G3 across the sensitivity range. However while the GF5 compares well against the comparison cameras up to a sensitivity of ISO 1600 the results above this value are noticeably lower.
Our analysis of the JPEG and TIFF (after conversion from raw) shows that while the results are respectable, they're nothing groundbreaking.

Amy has been writing about cameras, photography and associated tech since 2009. Amy was once part of the photography testing team for Future Publishing working across TechRadar, Digital Camera, PhotoPlus, N Photo and Photography Week. For her photography, she has won awards and has been exhibited. She often partakes in unusual projects - including one intense year where she used a different camera every single day. Amy is currently the Features Editor at Amateur Photographer magazine, and in her increasingly little spare time works across a number of high-profile publications including Wired, Stuff, Digital Camera World, Expert Reviews, and just a little off-tangent, PetsRadar.
