Sony A9 review


Sony's full-frame speed demon is too fast for its rivals

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

Screen won’t flip to the front ; That price tag

The insanely fast A9 is the new king of action and sports photography

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 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 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...

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 Review


The Sony A9 is the company's new flagship full-frame compact system camera for professionals. Aimed predominantly at sports, action and event photographers, the new Sony A9 can shoot continuously at 20fps for up to 241 RAW / 362 JPEG images with no...

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...

Sony A9 Review


A flagship, professional-class full-frame mirrorless camera is here! The Sony A9 aims to dethrone the DSLR as the go-to choice for pro sports and action photographers. Sporting a new 24MP stacked sensor, a super-fast processor, and burst speeds up to...

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 card slot is UHS-II compatible; Touchscreen underutilized; No lossless RAW compression option; No 4K/60p option
