While Sony's A7-series cameras have offered a tantalizing glimpse into Sony's vision for the future, they always seemed to be missing that extra bit of polish. Creaky lens mounts, a pokey autofocus system, pitiful battery life...

The A9 is the first full frame camera with tilting touch screen, just like my three-year old A5100. The A9 has decent phase-detection technology, too, with even more PDAF points than on my A5100 to get the brilliant video touch-to-spot-focus exclusively available only on Sony touch screen cameras...

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!

Was using Nikon for over 8 years. When switched to this camera - was amazed by all these new technologies. Great camera!

An astonishing high-speed mirrorless model that pushes the boundaries for full-frame sports and action cameras.

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

AF area not highlighted in viewfinder when moved via the joystick; Touchscreen woefully under-used

The A9 is the third Sony mirrorless camera designed to appeal to professional photographers. Whereas the A7R II targeted landscape photographers with its huge 42 megapixel resolution and the A7S II clearly appealed to videographers, the Sony A9's sheer speed makes it a serious rival to the Canon...

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.

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

The Sony Alpha A9 is a phenomenal camera. It's not without its faults – we'll be interested to see how the weather-sealing holds up when it's properly exposed to the elements for starters, while the absence of XQD card slots and very limited touchscreen control is disappointing.

Blistering performance; Incredibly fast and capable AF; No viewfinder blackout; Impressive level of customization; Excellent results from 24MP sensor; High-res viewfinder; Oversampled 4K footage

Weather sealing not as robust as rivals; No XQD card slots; Balance not great with long lenses; Very limited touchscreen control; Battery life not a match for rivals

My first impressions with a Sony a9 after using for 6 months while in transition from another professional camera outfitter. General. 1. Two SD card slots; a fast one in slot 1 and a slow in 2; both should have been the same. 2. No USB 3 3.
