Differences

Pentax K-5 IIs advantages over Panasonic LX100

Larger sensor
APS-C vs 4/3
More sensor area. Bigger is (generally) better.
Bigger pixels
~ 4.81 vs 3.77 microns
Better low-light and dynamic range (all else equal)
Fast startup
~0.60 vs 2.0 sec
Faster startup lets you catch the moment
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.

1,208 vs 553 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

Review Excerpt

Noticeably better sharpness than standard K-5 II; Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.
Prone to moire, aliasing, and false color artifacts; Can seem intimidating at first; Fewer autofocus points than competitors; Doesn't take advantage of high-speed UHS-I flash cards; Movie feature set is very dated and file sizes huge.
Read our Pentax K-5 IIs Review

Very good image quality; Great performance in most respects; Bright zoom lens with good macro performance; Photographer-friendly body easily fits in a coat pocket or small bag; Roomy, high-res built-in viewfinder; Decent battery life
Won't fit in a pants pocket; Relatively low resolution by modern standards; Zoom lens has only a modest telephoto; Soft corners at wide or tele positions; Aperture dial is too easily bumped; Bundled flash is fairly weak
