Should You Buy Sony’s New A6400 Mirrorless Camera?

Sony has announced a new mirrorless camera, the A6400, and it's biggest feature is an LCD touch display that can rotate 180 degrees. This allows vloggers and ambitious selfie-takers to easily frame a shot while standing in front of the camera.

But what else does the A6400 have to offer, and how does this model, available in February for $900, compare to Sony's other mirrorless cameras? Here's how it stacks up.

Price and specs-wise, the A6400 slots in between the A6300 and the A6500, which makes sense given its name. Like the A6300 and A6500, the A6400 has 425 phase detection points, along with 425 overlapping contrast detection points as well. However, the A6400 lacks in-body stabilization—helpful when doing hand-held shooting in low-light situations—which is only found on the A6500.

All four cameras have a tilting, 3-inch LCD touchscreen, but only the A6400's can rotate 180 degrees, so that you can see it if you're holding the camera so that its lens is facing you. In our review of the A6400, we found that when you're holding the camera close, the lens can obscure part of the display.

Other new features of the A6400 include an improved Eye autofocus feature, in which the camera will focus on a subject's eye (left or right) with a half-press of the shutter button. This works with both humans and animals. The camera also has a HLG (Hybrid Log-Gamma) picture profile, which will let owners record and show HDR video on compatible TVs. 

The α6400 costs $898 (body only), or $998 with a 16-50mm F3.5 – 5.6 lens, and $1,333 with an 18-135mm F3.5 – 5.6 lens.
