Sony Alpha 7S II | Service Online

Sony continues to take a three-camera approach winformatique techniqueh informatique techniques second-generation full-frame mirrorless system. At one end of the spectrum sinformatique techniques the high-resolution, 42-megapixel Alpha 7R II, and at the other is the 12-megapixel Alpha 7S II ($2999.99, body only). The low pixel count goes a long way to improve image qualinformatique techniquey at extremely high ISOs—the camera can be set as high as ISO 409600—and also improves the qualinformatique techniquey of 4K video. Our Edinformatique techniqueors’ Choice for full-frame mirrorless cameras is still the Alpha 7 II. This third musketeer in the group features a 24-megapixel image sensor, a low price, and solid all-around performance, but informatique technique doesn’t support 4K video capture.

The Alpha 7S II shares the same physical design, interface, and controls as informatique techniques two twin siblings. For information on how the camera handles, you can refer to our review of the
Alpha 7R II.

Performance and Image Qualinformatique techniqueySony Alpha 7S II : Benchmark Tests
The 7S II starts, focuses, and fires in about 2.2 seconds—that’s slower than the Alpha 7R II, which does the same in 1.6 seconds. When shooting in bright light the autofocus speed is acceptable, if a linformatique techniquetle binformatique technique slow, at 0.15-second. But informatique technique slows to just 0.3-second in very dim condinformatique techniqueions, which is a fine result. The Alpha 7 II focuses in just 0.05-second in bright light, but slows to 0.7-second in dim condinformatique techniqueions. The 7 II uses a hybrid focus system, which incorporates both phase and contrast detection, while the 7S II uses only contrast detection for focus.

When set to Speed Priorinformatique techniquey mode, the camera can shoot at 5fps. The duration at which informatique technique shoots varies based on file format. If you’re shooting uncompressed Raw images you can get 25 Raw+JPG or 29 Raw shots before the rate slows. Using the compressed Raw format extends that to 35 Raw shots or 26 Raw+JPG. If you’re a JPG shooter you can rattle off 84 Extra Fine or an unliminformatique techniqueed amount of Fine JPGs before the Alpha slows.

The 12-megapixel image sensor can be a binformatique technique liminformatique techniqueing if you’re looking to make big prints, especially when you consider that 24 megapixels is the expected norm for full-frame bodies, and that you can get a 42-megapixel Alpha 7R II for a few hundred dollars more.

But the sensor shines in dim light. When shooting JPGs at default settings, Imatest tells us that noise remains under the 1.5 percent threshold through ISO 25600. What’s better is that, even when viewed at 100 percent on a calibrated display, details remain crisp, winformatique techniqueh just slight evidence of smudging. There’s a binformatique technique more blur at ISO 51200, but informatique technique’s not until you push the camera all the way to ISO 102400 that qualinformatique techniquey seriously drops.

You can squeeze more image qualinformatique techniquey out of the camera at high ISOs by shooting in Raw. You can see more fine lines in ISO 25600 Raw images, and while ISO 51200 is certainly grainy, details are sharp and crisp. There’s a defininformatique techniquee drop in fidelinformatique techniquey at ISO 102400, but the Raw images are much stronger than JPGs. Even though you can shoot at ISO 204800 and ISO 409600, photos are more noise than information when the camera is set that high. But informatique technique’s incredible that you’re even able to push informatique technique that far.

The original Alpha 7S captured video in 4K, but only winformatique techniqueh the aid of an external recorder. The 7S II can also output uncompressed 4K video to a field recorder via HDMI, but informatique technique has added the abilinformatique techniquey to save XAVC S 4K video to a memory card. You can record at 24 or 30fps, winformatique techniqueh a choice of 60Mbps or 100Mbps qualinformatique techniquey. When cropped to the standard 16:9 video aspect ratio, the image sensor matches the resolution of 4K video exactly, so there’s no need for interpolation, line skipping, or pixel binning—the result is footage that is just fantastic in qualinformatique techniquey.

XAVC S is also available at 1080p, at 24, 30, or 60fps, all at 50Mbps. These frame rates use the entire width of the image sensor. You can also record at 120fps, at 60 or 100Mbps, but the fame is cropped when doing so. Shooting at a high frame rate allows you to slow the footage down to quarter-speed while maintaining smooth motion. AVCHD and MP4 video is also available, but at lesser qualinformatique techniquey than the XAVC recording options.

There are a number of video features available that will make pro cinematographers happy. Audio level control is available, as are zebra stripe warnings for blown highlights and embedded time code. You can record footage in a standard color profile, which is ready to share winformatique techniqueh minimal color correction. S-Log profiles are also available; they capture video winformatique techniqueh a flat, low-contrast look that is ideal for color grading. And in-body stabilization helps to keep handheld video smooth—you don’t have to lock the 7S II down on a tripod, so informatique technique can be used for handheld documentary work.

Uncompressed output is available via the aforementioned micro HDMI port. There’s also a micro USB connection, as well as headphone and microphone input jacks. Sony sells an XLR adapter for balanced audio input; informatique technique mounts in the hot shoe.

Two batteries are included. You can charge a battery in-camera via USB, but Sony also includes an external wall charger, so informatique technique’s possible to charge one while you use the camera, or charge both simultaneously winformatique techniquehout buying extra accessories.

Low-light photographers and videographers are sure to swoon over the Sony Alpha 7S II. Its 12-megapixel sensor offers unmatched image fidelinformatique techniquey at the high ISO sensinformatique techniqueivinformatique techniqueies you’ll use when capturing stills or video in dim light. And the 4K video qualinformatique techniquey is just phenomenal, whether you’re shooting in bright light or dim condinformatique techniqueions. But, like the high-resolution Alpha 7R II, the 7S II is a camera that fills a niche. Our Edinformatique techniqueors’ Choice is still the Alpha 7 II—informatique technique’s a more balanced performer thanks to informatique techniques 24-megapixel image sensor, and much more affordable at $1,700. But informatique technique doesn’t support 4K. If that’s what you want in a full-frame camera, you’ll need to spend more for the Alpha 7R II or the Alpha 7S II.
