The Sony a7S II shoots 4K internally with built-in stabilization and has 169 autofocus points – an upgrade from the original a7S, which required the use of an external recorder for 4K. Here are the other standout features:

• Relatively low megapixel count sensor designed specifically for video recording and features a full sensor readout without any of the line skipping found in very large megapixel cameras.
• Sharp footage devoid of major aliasing and moir when recording internally in 4K.
• A redeveloped recording setup that includes the ability to use S-Log3 Gamma and S-Gamut3 in addition to S-Log2 for increased dynamic range values by up to 1300% to better match high-end post-production workflows.
• Multiple timecode recording options to match different workflows.
• Focus peaking to aid in manual focusing, zebra markers to help judge overexposure, and an audio level overlay for mixing audio.
• ISO expandable from 50-409,600. This camera is well suited to shooting in low light conditions thanks to a new RGB color filter array, as well as a gapless on-chip lens design, which allows for low noise, high-sensitivity recording.

The a7S II, while still suitable for still shooting, is designed with videographers in mind and is especially designed for natural light video shooting. For an updated version of this camera, check out the Sony a7S III.
