dpreview.com has not tested this model. In the preview, it raises some questions to consider while evaluating whether or not this camera is for you.
"A hit-for-six, slam-dunk, home-run?
"If it's successful in its attempts to step up from the performance of the a6000 then the a6300 could be sensational. However, there are three questions that we'd like to see addressed. The first relates to handling: why does a camera costing this much only have one dial that you can access without changing the position of your grip? The rear dial isn't the worst we've encountered, but at this price point, we'd usually expect to find a dial under the forefinger and another under the thumb while maintaining a shooting grip.
"The second relates to lenses. Sony is bundling the a6300 with the 16-50mm power zoom that's far more notable for its convenience than its optical consistency, a move that's likely to raise the question of what other lenses to fit. Sony offers a handful of reasonably priced APS-C-specific prime lenses as well as some more expensive FE-compatible full-frame primes. However, in terms of standard zooms, you're currently limited to the inexpensive 16-50mm, the older 18-55mm at aftermarket prices or considerably more expensive options such as the 18-105mm F4 or the 16-70mm F4 Zeiss that costs around the same amount as the camera again. The success of Sony's full frame a7 cameras is only likely to improve third-party lens availability but there's a risk that Sony's focus will be on those full frame users for the foreseeable future.
"Our final concern is the lack of joystick or touchscreen to re-position the AF point. This may be mitigated during stills shooting if the lock-on AF system works well enough (starting AF tracking and then recompose your shot in the knowledge that the AF point will stay where you want it), but it appears to be a real omission for refocusing while shooting video. The a6300 is improved over previous models, in that pressing the center button on the four-way controller toggles into AF point selection mode, a decision that's retained even if you turn the camera off and on again. We'll see how significant all these concerns turn out to be, as the review unfolds."

dpreview is pretty honest about its concerns after testing cameras, whereas many 'reviews' are scarcely more than a marketing summary by the camera company and fail to disclose any issues.
