Problem: "My pictures are blurry."
Fix: You are likely in "AF-S" mode. Switch to AF-C. Also, check your shutter speed. Rule of thumb: 1/(focal length x 2). For a 50mm lens, shoot faster than 1/100.
Problem: "The 4K video looks wobbly (Jello effect)." Fix: You are experiencing rolling shutter. Turn on "SteadyShot" to Standard (not Active), or use a gimbal (DJI Ronin SC). The a6400 has bad rolling shutter; avoid whipping the camera left to right quickly. Do that, and it still competes with cameras twice the price
Problem: "Face detection doesn’t work." Fix: Go to Menu → Camera 1 → Face/Eye AF Settings → Make sure "Face Priority" is turned On. Also, ensure you haven't accidentally turned off Face Detection in the Fn menu.
Problem: "The image is too orange/yellow." Fix: White Balance is on "Auto." For skintones, set it to "Daylight" (5000K) outdoors or a custom Kelvin (3200K) indoors. Or shoot in RAW and fix later.
