Hi
Shelley, you are welcome on this forum, its a pleasure to see you here !
Some thoughts to this date after two month of using DR400...
If we are talking about manufacturer, it would be great to:
1) expand brightness adjustment range, to be able to make picture even darker, cause in the minimal (left) position of current settings the picture is far more brighter, than i would like to see, in my particular circumstances.
2) increase video bitrate from current 7400 to, lets say ~10000 Kb\s or even 12Mbit, to improve overall picture quality and small moving particles in the frame especially. Current SD card prices allowing to do so with ease.
3) do something with image softness on the sides of the lens.
Cause the problem is common in a varying degree. If your service doesnt recognize this problem and consider it as typical, maybe its time to renew or reconstruct a lens, to make image sharp all over a frame, like Papago P3 (damn, its tack sharp !).
