In every field of technology, there are liminal moments when the new begins to outpace the old, and the bell begins to toll for the previous generation's greatest achievements. As I look past the Sony a9 across my collection of digital SLRs, I can hear a distinct ringing.

Excellent handling and controls; Superb autofocus tracking; High-speed shooting with minimal distortion; Excellent electronic viewfinder with zero blackout; Impressive battery life;

Sony’s high-end mirrorless cameras continue to impress, and the A9 represents a genuine challenge to Nikon and Canon’s top-of-the-range DSLRs. 20fps stills shooting, with continuously-updating autofocus and exposure, from a full-frame lens? That’s something none of this camera’s rivals can touch at the moment. Is this a camera for non-professionals, though? At £4,500, it’s a tough sell – the Sony A7 series offers fantastic (albeit slightly slower) models for £2,000 less, and I’d be inclined to recommend those above the A9 for the vast majority of people. For those five percenters who shoot sport, wildlife or photojournalism and need the speed, though? The A9 is the fastest camera in town.

Incredibly fast stills shooting; 5-axis image stabilisation; Solid, compact build; Good battery life; Cheaper than Canon and Nikon rivals; Slick 4x slo-mo video;

Recent market statistics confirm that mirrorless cameras represent the only sector of the 'serious' camera market that is showing any real growth. The α9 is smaller and faster than either the Canon 1DX Mk II or Nikon D5 and its high ISO images are noticeably better and its video quality is superior.

We don't all need a camera as quick off the mark as the A9, but for photographers who demand speed in both autofocus and stills shooting, it's being pitched as something truly special.

Though we as an organization avoid reporting on rumors and speculation of future camera products, we can't help but get just as excited as the next person speculating about upcoming new gear! One of the most hyped and most rumored cameras in recent years has been the Sony A9.

New sensor offers incredible performance; Excellent image quality at low & high ISOs; Very good dynamic range; Phenomenal 20fps burst speed & deep buffer; Very good battery life for a mirrorless; 4K video; Dual card slots

Slow buffer clearing; Only one UHS-II card slot; Touchscreen underutilized; No lossless RAW compression option; No 4K/60p option

The Sony Alpha 9 (or A9 for short) is a high-speed full-frame mirrorless camera that's designed to go head to head with Canon and Nikon's flagship professional DSLRs. It's capable of shooting 24MP images at 20 frames per second while keeping focus on moving subjects, and costs £4500.

I own and use the Sony A9 (ILCE-9/B) since August 2017 and had sufficient time for testing, with landscape, nature and street photography. I mostly used the Zeiss Batis 85mm. In summary, I can say that this is a really strong camera, and it better be at with this price! Is the camera perfect - No!

Able to perform well for work and even some games or entertainment, this notebook is an excellent choice for the average user.
