Panasonic Lumix DMC-GX80: test results
Here we’re showing preliminary test results from the GX80 to see the effects of removing the optical low pass filter. We don’t have any way of processing the camera’s raw files at the time of writing, so for now can only look at JPEGs, but this should still give some idea of the camera’s image quality.
Below are 100% crops from camera JPEGs of our resolution test chart, shot at each ISO setting using the Olympus 60mm f/2.8 Macro at f/4.
Multiply the number beneath the line by 200 to get resolution in lines/picture height. What we can see here is clean resolution of fine detail to around 3200 l/ph, then blurring of the lines together with no obvious sampling artefacts, before some false detail appears at higher frequencies.
Impressively, noise only has an obvious impact on resolution above ISO 3200: however the top two settings don’t look great. However, this doesn’t look very much different to what we previously saw from the 16MP Panasonic G7, so in JPEG at least we’re not getting much more resolution.
