Very good M4/3 camera which I enjoyed using for almost a year, until switching to the Olympus EM1. The reason for the change was Panasonic has image stabilization in their lenses and the Olympus has it built into the camera, which for me was an advantage at the time.

I could go on and on about how awesome this camera is, and how sick it is that's a true 'film/cine 4k DSLR/DSLM' with amazing qualities and what not, but all I'm gonna say is this. With the right lenses and the right adapters... this thing rivals even a 2k-4k RED!

24p And 24hz Modes; Easy To Use; Fast/accurate auto-focus; Good Image Quality; Good Image Stabilization; Large Clear LCD; Small / Compact; Truly Cinematic Look; Variable Frame Rates

10bit 422 Hdmi Only Rec; 420 Compression To Card

This my third GH4. I primarily shoot classical music concerts and operas/musicals with locked off cameras, so having a camera that stops recording at 29 mins 59 seconds, is not an option for me. Lighting is not normally an issue, so f/4.0 at 640 ISO covers most of my theater shooting needs.

The Panasonic GH4 takes the impressive specs and performance of the GH3 and kicks them up a notch -- a big notch -- with faster burst shooting, quicker AF, and a host of other improvements, not to mention tons of new video features.

Excellent still image quality for its class; Fantastic, highly-detailed video quality; Superior video recording chops with 4K video (both Cinema 4K and Ultra HD); Responsive all-around performer with great AF performance and burst shooting; Rolling shutter is minimal with 60p and 30p video; Splash-...

High ISO performance not as good as some APS-C models (IQ drops quickly past ISO 3200); Overall still image quality not significantly better than the GH3; Sluggish buffer clearing with RAW files; Rolling shutter noticeable on 4K video; Not as compact as most mirrorless cameras, High ISO performance...

We've often thought of the Panasonic GH series as the best consumer interchangeable lens system for video capture on the market. It's not hard to see why: the Panasonic Lumix GH4 offers 4K video capture at usable frame rates. On paper that's untouchable at this level.

Fast in all conditions; 12fps burst mode; silent electronic shutter option; movie mode as good as it gets and will sell the camera alone; fully featured screen and electronic viewfinder; pinpoint and customisable autofocus options

Lacks smooth gradation in images; needs better battery life; some button placement cramped; would like a larger viewfinder; price may seem a lot if you're not here for 4K video; autofocus generalisation in low-light conditions

Back in 2008 Panasonic released the world's first CSC, the LUMIX G1. Six years on, the Japanese-based manufacturer has demonstrated it's still driving the CSC market forward with its new flagship model, the GH4.

Panasonic Lumix G cameras already sit a notch above other compact system cameras (CSCs) and SLRs for video picture quality. The GH4 is the latest addition to the range, and from the outside it's hard to distinguish from the GH3 .

Fantastic Video camera.

This is the best camera for video that you can get at this price range. The panasonic G7 is similar and cheaper however is less practical as a video camera, no high bitrate 1080, no V-Log, no weather sealing, no headphone jack.

4k Is Great; Amazing Value For Money; Great Picture Quality; Tilt Screen Is Nice

Noisy Camera; Poor Operation in Low Light

I moved across to this from the 5D III and am blown away by the video quality. Film in 4K and show off your movies in HD - they look so much better - or pan and zoom the 4K footage in a HD sequence.

exactly as it all the reviews say, pro level camera
