One of the more interesting aspects about Panasonic's Lumix camera line-up is the way that each model - while often tilted towards different situations and contexts - inevitably informs the next.

Night mode; Shoulder-mounted information display; 6.5-stop stablization; 0.04-second autofocus; Weather-sealed design

Videographic capabilities not as robust as GH5

Quality product, ergonomically well designed, enormous number of features and very impressive lens - bought on line and properly packaged and competitively priced - not cheap but for serious photos worth it

Physical standouts include a top plate LCD - a true rarity in mirrorless-land - and one of the largest electronic viewfinders on a Micro Four Thirds cameras. It has an equivalent magnification of 0.83x and an eyepoint of 21mm.

The Lumix G9 is a confident and tremendously satisfying camera, and like the Olympus OMD EM1 Mark II and Sony Alpha A9 before it, continues to redefine what we can expect from high-end mirrorless bodies.

All interchangeable lens cameras share common feature sets, with some offering higher sensitivity (ISO range), faster shutter speeds, or enhanced video capabilities. Aimed squarely at photo enthusiasts and advanced photographers who can appreciate and make use of its many creative imaging options,...

The company's flagship stills model, the G9 is a Micro Four Thirds with a whole lot of punch. With a 20.3MP sensor, and powered by the trusty Venus processing engine, it's capable of shooting at 20fps, blackout free in continuous autofocus, or a massive 60fps with the focus set.

Panasonic's new photography flagship takes some useful steps forward from the video powerhouse GH5, from upgraded autofocus and image stabilization to 20 fps burst speed and a massive 80-megapixel high resolution mode. Here are our thoughts and sample images.

Panasonic commits to stills photography with its new high-speed, high-end mirrorless camera...

20/60fps continuous shooting; 4K UHD video; Fast and effective autofocus

Some viewfinder lag in burst mode; Smaller sensor than most rivals; Lacks DSLR battery life

Panasonic wants its new Lumix G9 to be the GH5 for still shooters; a small, light, fast and flexible alternative to traditionally bigger cameras for outdoor and action photography.

Panasonic hopes a combination of speed, tonal tuning and body design will tempt serious photographers.
