As a mirrorless camera the G9 has an electronic viewfinder (evf) – in the case of the G9 this is a 3,680k dot OLED panel.
Lumix G9 First Impressions – Ergonomics
Panasonic have clearly spent a lot of time working on the ergonomics of the G9 and it really shows. They have managed to squeeze into a relatively compact body the best features of both m43 and DSLR formats. In the hand this camera feels superb – it is as good if not better to handle than any other camera that I am aware of and feels exceptionally well built. For me it is neither too big nor too heavy.
