I just purchased an X5 and my first experience is with the updated firmware. I've searched of the forum, but I am wondering if I might have abad camera or whether the firmware might have problems. Any input would be appreciated. 1) My gimbal drifts slightly back and forth. It's not horrible and it is slow, but it is noticeable. Is this normal? 2) I can't set the 50hz/60hz in the anti-flicker menu. It resorts to 50hz even though I am in NTSC. 3) White balance doesn't work. AWB gets close, but manual white balance or incandescent or other settings just give me the wrong results. It's almost like the white balance is changing the tint rather than the actual white balance. Anybody know why? 4) Above about 800 ISO, I see really bad flicker in the shadows. I've never seen anything like it on any other camera. I've been shooting video for awhile and I understand the relationship between noise, iso, and various gammas and curves, but this makes me think there is something wrong with the gain controller or any noise reduction they might be doing on the sensor. I thought the newest firmware was supposed to help with this. Is it just my camera?
