The Sony A9 is a brilliant camera, fast, responsive and delivering superb results. If it is just high-quality images that are required though, the A7R II will save £2000 that can be spent on fine lenses instead and will give higher resolution. There are also plenty of alternative Sony bodies that will give entry to the system at much lower cost.
However, it looks as though Sony's intention is to take on the fast shooting that previously had been the sole purview of the DSLR. The “big guns” from Canon and Nikon are more expensive, much bulkier and definitely much heavier. Add the appropriate lenses though and even the Sony A9 would pack a fair weight if such lenses were available for the system.
Looking at what the A9 can do that other cameras cannot, then the 20fps is impossible to beat, especially with no blackout between images. It is likely that the DSLR, with its mechanical constraints, can never surpass what might be possible with a mirrorless camera. For various reasons of lens availability and professional backup, the Sony has a little way to go yet, but it delivers some unique possibilities as it is and is a fine camera.Read more

The Alpha 9 is simply stunning – both as a technical achievement and as a tool for capturing fast-moving action. The silent 20fps continuous shooting mode can capture shots you would once have missed, and the AF system is complex but extremely effective. Bravo!
- Completely silent 20fps mode
- Fast and effective autofocus
- No viewfinder blackout
- Unbalanced with larger lenses
- Shorter battery life than DSLRs
- EVF is good but not perfect

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 EVF that doesn't blackout when you're shooting, and you've got a camera that can mix it with the best that Canon and Nikon have to offer when it comes to shooting action.
- 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
