Dear Paladin,
In the tutorial, the narrator described that the aperture would be automatically adjusted in Auto and shutter priority modes. I do think that the aperture of the Z3 is fixed for any given focal length. In the demonstration of adjusting shutter speed from 1/160 Sec to 1/1250 Second (video time stamp from 2:12 till 2:18), I did not see any change in aperture value (F number) on top of the DJI GO App screen. All I saw were changes in exposure, not compensatory changes in aperture to maintain correct exposure. Please clarify whether the narrator was describing the Z3 correctly or not.
Besides, I noted that when the Z3 was zoomed in from 22mm to 77mm in manual exposure mode with fixed ISO setting, the F number shown on top of the DJI GO App did not change and maintained at F 2.8, whilst the exposure changed from bright to dark (down by approximately 2 stops). According to the specifications of Z3 announced by DJI, at 77mm the maximum aperture (and I think it is fixed) is 5.2. Was there a bug in the DJI GO App?
Please clarify.
