To compare the resolution and noise levels of the Panasonic Lumix G90 / G95, I photographed the following subject at every ISO setting, then repeated the sequence with the Panasonic Lumix G9 and Sony A6400 using identical exposures for each ISO value. I’ve taken crops from each image indicated by the red rectangle and presented them at 100% for close inspection in the table below. These are taken from out-of-camera JPEGs, although I also shot in RAW and hope to add RAW results in the future.
At the lower sensitivities all three cameras share a similar degree of detail, proving the G90’s photo quality is essentially the same as the G9 and that there’s no resolution benefit to the A6400. But you will notice the A6400 crops are a little brighter, indicating its ISO values are actually a tad more sensitive than the Lumix values in practice. In terms of noise and noise reduction, I’d say the A6400’s bigger sensor begins to show a benefit at 1600 ISO and especially at 3200 ISO upwards where there’s less smearing and more detail retained than the Lumix models. But as you can see, all three still suffer at higher sensitivities.
Check prices on the Lumix G95 at Amazon, B&H or Adorama. Check prices on the Lumix G90 at WEX. Alternatively get yourself a copy of my In Camera book or treat me to a coffee! Thanks!
