Sony A9

 

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...

Sony a9

 

The Sony a9 camera packs an incredible autofocus system, full-frame image sensor, and 4K video, all in a body that's smaller than most SLRs.

Shoots at 20fps with subject tracking. Full-frame 24MP image sensor. 93-percent focus coverage. Electronic shutter eliminates blackout. Also supports traditional mechanical shutter. Large, crisp EVF. Tilting touch LCD. In-body 5-axis stabilization. New...

Pricey. Only one slot UHS-II compliant. Dense menu system. Uncompressed Raw capture cuts speed to 12fps. Doesn't include external battery charger. Lens library missing wide aperture super telephoto options.

The Sony a9 is a big step forward for mirrorless technology. It betters the fastest, most expensive SLRs in capture rate, spreads its autofocus system across almost the entirety of a full-fame image sensor, and has a really fantastic EVF—one that, in...

The Sony A9: If you photograph action, you'll want it (hands-on)

 

It's not perfect and it's too expensive for many of us, but the A9 is fast, accurate, lightweight and delivers on photo quality.

Sony Alpha 9 (a9)

 

Sony started this morning looking for WOWS and, in announcing their newest full-frame flagship ILC, I think they earned 'em.

Sony A9 initial review: Phenomenal speed from the full-frame mirrorless master

 

Merited on performance alone, the Nikon D5 and Canon EOS 1D X II no longer monopolise the market for professional sports, wildlife and wedding

Ridiculously fast 20fps burst with full-time AF and no display blackout ; Phase-detection AF with 93 per cent frame coverage ; Lovely electronic finder with 120fps refresh rate ; Improved battery life at 650 shots

Too small to be comfortable with larger lenses attached ; LCD touchscreen is no match for competitors ; No picture profiles or S-Log for video

The Sony A9 is a mightily impressive camera, especially considering it is Sony's first attempt at a camera designed for professional sports photographers and the like. It's a speed demon and using it for sports is pretty much cheating - it'll get you...

Sony Alpha A9 review

 

Taking the fight to Canon and Nikon

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

The Alpha A9 doesn't fail to impress. The AF system Sony has blessed this camera with is not only incredibly quick, the tracking performance needs to be seen to be believed. Partner that with incredibly fast 20fps burst shooting, and a large and bright...

Sony A9 full-frame mirrorless camera : For some time there has been talk about the new Sony A9 Full-Frame camera. Today was the day Sony officially announced its most advanced and innovative digital camera. The Sony α9 (model ILCE-9) offers a level of...

The new Sony A9 also offers 4K (3840x2160p) video recording across the full width of the full-frame image sensor. When shooting in this format, the camera uses full pixel readout without pixel binning to collect 6K of information, oversampling it to...
