The Sony Alpha A9 is the ultimate mirrorless full-frame camera

Adjust Comment Print

The new A9 is a full-frame mirrorless camera that comes packing a load of features that should suit professional photographers looking for a great mirrorless offering.

Battery life has consistently proven to be a weak point of mirrorless cameras, so it's good to see Sony working to extend how much time you can spend shooting.

Those of you eager to know, the Sony α9 full-frame mirror-less camera has the much talked about 4D Focus that includes 693 point AF system, covering almost 93 percent of the image area, reliable object tracking and fast-focusing speed. This new sensor is coupled with a completely new Bionz X processing engine and front-end LSI to boost performance.

The hybrid AF setup is said to be about 25% faster than the Alpha A7R II, and should ensure fast-moving subjects are captured without difficulty.

This announcement comes just days after Sony revealed that their continued growth has vaulted them into the number two overall position in the USA full-frame interchangeable lens camera market. There's also a QVGA, 3686K dot OLED viewfinder, which is the highest-res, and brightest model Sony has ever used.

These focal point cover 93% of the sensor.

There's also vibration-free shooting at speeds up to 1/32,000 sec with a fully electronic and silent shutter, along with a 5-axis image stabilisation system.

The highest-resolution viewfinder Sony has ever incorporated in a camera, it has a 0.78x magnification and a Zeiss T* coating to greatly reduce reflections, and has a fluorine coating on the outer lens that repels dirt.

This all adds up to a luminance that is 2x higher than the XGA OLED Tru-Finder from the α7R II, creating a viewfinder image with a brightness level that is almost identical to the actual scene being framed, ensuring the most natural shooting experience. The frame rate of the Tru-Finder is customisable, with options to set it for 60 fps or 120 fps to best match the action. Low-light performance is also aided by the new in-camera stabilization system, good for a five-step shutter speed improvement when shooting handheld. It's possible to save 14-bit precision RAW files. The new sensor/processor combination is up to 20-times faster than the unit in previous mirrorless Sony models. Sony has included two media card slots including one for UHS-II media in the α9.

A new multi-selector joystick on the rear panel provides an easy way to shift focus within the frame when shooting in Zone, Flexible Spot or Expanded Flexible Spot focus area modes.
