Several sites have been trying out the Sony RX100 mk III and have finally been sharing their results along with video samples.
Sadly the 120fps 720p mode is resolution starved and soft. However it does look a little bit better than many cameras in the price bracket. After looking at the quality, we matched it to be just a smidge better than the iPhone 5s but just a tad below the GoPro Hero 3+ when it comes to 120fps slow motion. It is now positioned in 10th place on our HSC Slow Motion Quality Guide.
