Sony’s 4K-cable Alpha a7S can be preordered on B&H Photo Video for $2498 and is expected to release on July 8.
The successor of the Sony Alpha a7, the a7S has been announced for a July release, which can be preordered on B&H Photo Video for $2498. This will include the body only. The camera, which will be mirrorless, and include a full-frame sensor, will also shoot content at 4K. There’s no word yet if there’ll be body-len’s kits available at launch. The Alpha a7S was just revealed at NAB in Las Vegas on a month prior to its release announcement.
The Alpha a7S features a full-frame 12.2 MP Exmor CMOS sensor and BIONZ X image processing. The BIONZ X processor provides a great dynamic range and low-sound combination. The ISO can be extended to a very impressive 409,600. The sensor includes a gapless lens design, which increases the efficiency of the light gathered and provides overall better image quality.
With the new sensor and processor, the camera is capable of shooting images continuously at 5 FPS and includes a 25-point contrast detection AF system. The camera also includes built-in WiFi, which is a feature in many of today’s prosumer and professional cameras.
In regards to recording video, the a7S can output uncompressed 4:2:2 UHD 4K video in 30p/24p/25p, but will require an external drive to shoot 4K footage. There is also the usual 1920 x 1080 in 60p/60i/50p/50i/24p, which can be recorded internally. There’s also an increase in dynamic range, thanks to support from S-Log2 gamma. There are even video-standard recording features, such as a time code and zebra markers, built into the firmware.
Sound is recorded in ACC/Linear PCM format. The device includes an internal stereo microphone and a jack for an external microphone, as well as a jack for headphone monitoring.
In terms of body design, the a7S includes a 3-inch 921.6k-dot tilting LCD monitor and a 2.36 million-dot OLED electronic viewfinder for monitoring and reviewing.
Sony has also recently announced their Cyber-shot RX100, greatly expanding their camera lineup to appeal to all users in the market, casual and professional.
The a7S’ biggest competition will be Panasonic’s Lumix GH4 mirrorless micro four thirds camera, which also supports 4K shooting. The Lumix GH4 is expected to release in late-May, according to B&H, with a pricetag of $1700.
