Sony announces A7S. How does it compare to Panasonic GH4?
A quick glance at the specs seems to indicate that the Sony A7S may be the better choice if shooting in ultra-low-light is a requirement, otherwise the Panasonic Lumix GH4 seems to be the better all around camera. Of note:
- The A7S requires an external recorder for 4k, the GH4 can internally record 4k to SD cards.
- Even then, the output is 8bit and interlaced vs. the GH4’s progressive 10bit. (Better for color correction.)
- A7s doesn’t offer true DVI 4k, rather it captures and records UHD.
- A7s 1080P is limited to 50mbps. GH4 can record 1080P at up to a whopping 200mbps.
- A7S slow motion (120fps) is limited to 720P. GH4 slow motion (96fps) is at full 1080P.
- A7s’ E-Mount has fewer native lens choices compared to the GH4’s MFT mount. MFT is also more adaptable.
- A7s promises an XLR breakout box in the future. GH4 interface unit offers both XLR inputs and SDI outputs.
- A7s utilizes lower resolution viewfinder and fixed LCD monitor. GH4 offers higher resolution on both, and GH4’s monitor is OLED and adjustable.
