If you’re looking for an all in one camera, the option to shoot 4K, slow motion and tons of other features, this is a fantastic option. This is a complete 4K camera and can record 4K videos internally. No need for external storage and rigs. Like the A7S the GH4 is mirrorless. Because no mirror is used, the overall camera is compact compared to the Canon EOS 70D. Lenses for mirrorless cameras such as the GH4 and A7S also tend to be quite small by comparison. So if portability matters to you that’s something to keep in mind.
The Panasonic Lumix DMC-GH4 Mirrorless Micro Four Thirds Digital Camera is a true hybrid camera designed for both professional photo and video use. Comparing price to value – this the best 4K Camera to opt for. While you may not be in need of 4k videos for now, but 4K is the future and will be a standard not far from now. It features a 16.05-megapixel Digital Live MOS sensor and a 4-CPU Venus Engine, capable of capturing high-resolution JPEG and RAW stills, as well as Ultra HD 4K 3840×2160 30p/24p and cinematic DCI 4K 4096×2160 video at 24p. Like its predecessor, the GH4 features a weather-sealed magnesium alloy body, while offering increased resolution on both the OLED monitor and electronic viewfinder. It also features built-in Wi-Fi with NFC technology, in-camera creative controls, and a high-speed 49-point autofocus in both photo and video mode.
One of the most prominent features of Panasonic LUMIX GH4 is unlimited2 4K video recording in both Cinema 4K: 4096×2160 / 24 fps, and QFHD 4K: 3840×2160 / up to 30 fps in MOV/MP43. Print ready high resolution 8.8 megapixel still frames can be recorded during video capture, making future proofed Hybrid Photography a reality for any photographer.
The GH4 delivers video quality surpassing many professional video cameras. Video can be recorded in a variety of formats, from efficient AVCHD and AVCHD Progressive to 200 Mbps All-Intra, and 100 Mbps IPB MOV and MP4 formats. And because the GH4 is a global camera, the system frequency can be switched between 59.94 Hz (23.98 Hz) and 50 Hz, yielding a variety of recording options including 23.98p, 25p, 29.97p, 50p, and 59.94p. The system can also be switched to 24 Hz to capture true 24p in HD and 4K resolutions. This camera, plus a speed booster and some fast glass can give you amazing results.
The Panasonic GH4 and the Sony Alpha A7s were released at relatively the same time and many enthusiasts have reviewed them to be the best. So if you want a true 4K experience go for the Panasonic GH4 – if you are more into low light the Sony Alpha A7s is for you.
