Sony's 24.2-megapixel A6400 APS-C camera was a surprise, filling a gap between the A6300 and A6500 that didn't really need to be filled. Both in how it looks and the technology inside, it didn't seem like a great leap over the A6300. It also lacks important features (like in-body stabilization) found in the A6500. However, with 4K video, a pop-up screen, a microphone jack and reasonable $900 price tag, I thought it might make a great poor-man's vlogging camera.
