Sony Alpha 7S Key Features And Specification Review

The Sony Alpha 7S is the third design in Sony full-frame mirrorless collection, a 12MP camera that places as much focus on its film catch abilities as its still picture expertise. While the a7S is a capable still shooting, Sony design has highlighted that its real focus (no pun intended) is video.

The first thing you need to know about the a7S is that it can history 1080p video inner or be used to outcome 4K film to an outside recording unit. The interior 1080p video is documented using the XAVC S structure, a more consumer friendly edition of Sony XAVC system. This is the first of the company cameras to use the structure, which liberates you from the bitrate limitations of the AVCHD standard.

Sony Alpha 7S Body And Design

The Sony Alpha 7S manages – control buttons, calls and choices – are similar to those on the a7 and a7R. In short, manages are reasonably presented, with a few exceptions: the back switch could stick out out a bit more, the videos key is too far out of the way, and both the selection and C2 control buttons are unusually placed.

The camera has two primary calls that leave the top dish, as well as the acquainted back switch that enhances as a four-way operator. The primary calls always manage exposure: system change in P method and aperture and/or shutter rate in the others. The back switch can have up to five configurations sent to it, though that can be risky, as unintentionally switching said switch is very easy. There are two ways around this: simply allocate nothing to the back switch, or convert on the secure operate which needs a button-press before it may change anything.

The digital camera’s main selection is long and, though divided into sensible an eye, can be a little difficult to find things in. Fortunately it’s unusual that you’ll need to invest time going through it, since there is also a completely user-definable ‘Fn’ selection. This signifies that, despite our bookings about recption menus system, overall the a7S is a satisfaction to capture with. The digicam is sensitive, concentrates easily in good mild (but not-so-well in low light), and the LCD and EVF have no recognizable lag. While a touchscreen display screen like the one found on the Panasonic GH4 would’ve been awesome, it certainly not affects the capturing experience.
