Differences

Pentax K-1 advantages over Panasonic GH5

Larger sensor
35mm vs 4/3
More sensor area. Bigger is (generally) better.
Bigger pixels
~ 4.88 vs 3.34 microns
Better low-light and dynamic range (all else equal)
High resolution composite
Yes vs No
Combine multiple shots to form a super hi-res version
Higher effective ISO

Higher effective ISO

Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.

Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

You can learn more at our glossary entry.

K-1 test data on DxO Mark GH5 test data on DxO Mark

3,280 vs 807 iso
Take photos in low light with less noise
More dynamic range

More dynamic range

Cameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.

Think of a brilliant sunset on a rocky beach: Bright sunset in the background, with dark rocks in the foreground. High dynamic range means more of the extremes will be faithfully reproduced.

Longer stills battery life

Cameras with longer battery life can take more photos before exhausting their batteries.

Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
