Review Excerpt

Great image quality; Good high ISO performance for its class; Improved JPEG processing; Fast autofocus; Fast ~9fps burst mode.
Smallish field-sequential EVF; Below average battery life; No mic/headphone jacks; Noticeable crop on 4K video.
Read our Panasonic GX9 Review

Excellent build and comfortable handling; Bright, roomy viewfinder and articulated LCD; Great image quality; Good performance for the class; In-camera stabilization, GPS and Wi-Fi; Incredibly feature-rich design.
Bulkier than APS-C DSLRs; Top ISOs are for the spec sheet, not the real world; JPEGs are a bit punchy by default; Slow startup; Below-average battery life; Only a relatively modest update to the K-1.
