Sony has announced its flagship Alpha series mirrorless camera, the Alpha 1. The A1 combines the best of Sony's other mirrorless cameras — the A7R, the A7S, and the A9 — and takes it all to the next level to create the best hybrid photo and video camera that the company currently has to offer.
The A1 has a new 50.1MP full-frame stacked
Exmor RS CMOS sensor with an upgraded BIONZ XR image processor. The new sensor
offers 15+ stops of dynamic range for videos and stills through its ISO
100-32,000 range (expandable to 50-102,400 for stills). You can also create
199MP images using the upgraded Pixel Shift Multi Shooting mode and Sony's
Imagine Edge desktop software.
The new image processor enables some of
shooting experience on a digital camera. The A1 can shoot full resolution RAW images
at 30 frames per second with a buffer large enough to fit 155 compressed RAW or
165 JPEG. It can do 120 AF/AE calculations per second with an AE response
latency as low as 0.033 seconds.
Sony has also updated the electronic
viewfinder to keep up with the camera. The 9.44 million dot, 0.64-inch Quad-XGA
OLED has a refresh rate of 240Hz, the first for any camera in the world. It
offers a 0.90x viewfinder magnification, a 41° diagonal FOV, and a 25mm-high
eyepoint. The main display is 3.0-inch 1.44 million dot LCD with a touchscreen
and tilting design. The A1 features the same new UI from the A7S III.
The new autofocus system has 759 phase
detection points and real-time eye AF for humans, animals (photo and video),
and for the first time on an Alpha camera, birds (photo only). The tracking
algorithm can even maintain focus if the bird suddenly takes flight.
The A1 features an improved electronic
shutter with 1.5x less rolling shutter than the A9 II. It's also the first
camera to offer anti-flicker continuous shooting in any lighting condition. And
for the first time on an Alpha camera, it can sync up to 1/200 of a second with
a flash. Meanwhile, the mechanical shutter can do it at 1/400 of a second
thanks to a new lightweight carbon fiber shutter curtain and dual driven
shutter system.
For video, the A1 can do 8K 30p 10-bit at
4:2:0 in XAVC HS Long-GOP. It uses the full width of the 50.1MP sensor and
captures 8.6K, which is then downsampled into 8K. For 4K, the A1 offers 4K at
60p and 120p at 10-bit 4:2:2 in Long-GOP and All-Intra. The 4K isn't
downsampled from 8K but the camera does Heating has become an issue on these
cameras as they keep getting smaller and doing higher resolutions. Sony says
the A1 can do 8K video for 30 minutes, thanks to its new heat-dissipating
structure inherited from the A7S III.
The A1 also inherits some of the color
science from the more expensive cinema cameras, such as the FX6, FX9, and the
VENICE. It supports the new S-Cinetone color profile, the first for any Alpha
camera. It can also do S-Gamut3 and S-Gamut3.Cine color, which should make it
easy to color match it with the aforementioned cinema cameras from Sony. The
full-sized HDMI offers 16-bit RAW output to an external recorder. The A1 has
built-in image stabilization, promising 5.5-step shutter speed advantage. The
camera also saves gyro data, which can be imported in Sony's Catalyst Browse
software to stabilize the footage.
The A1 also has some serious connectivity,
including a Gigabit Ethernet, dual-channel 2x2 MIMO 802.11ac Wi-Fi, and USB-C.
You also get dual card slots, with each slot capable of taking the UHS-I and
UHS-II SDXC/SDHC cards or the new CFexpress Type A cards. Lastly, there will
also be an optional battery grip (VG-C4EM) that will double the battery
capacity.
The Sony Alpha 1 is priced at US$ 6500 and
will be available in March 2021. The A1 is aimed at wildlife, sports,
landscape, wedding, and product photographers or photojournalists who want the
best, and have already invested in the Sony ecosystem. It should also double up
as a very competent video camera, as it basically inherits everything from the
critically-acclaimed A7S III and takes it even further with 8K support. It
competes with the Canon EOS R5, although the R5 does have issues with
overheating. If you want a camera that seemingly does it all, the A1 should be
high up on your list.
