Does the backup camera on the nex support dynamic guide lines? For instance I've seen on some cars e lines will tilt if you turn the steering wheel while backing up. I just had my oem camera retained with my nex5000 but it seems the guide lines are static.

No, you see those as an OEM from the car manufacturer usually.

I can tell you that any camera will work, I kept the Kenwood camera I had (the one that can switch angles , I forget the number) and it works just fine... because it has a button I can still use the angles...  but the lines are static
