Hi friends, to date I was not able to use my ART series objectives from sigma to canon in my ronin s. I use a 5d mk IV canon.
After reading in the forum I discovered how I can use the manual focusing wheel of my ronin s in my canon camera with ART sigma lenses.
To refresh the memory for those who do not know, the Dual Pixel CMOS AF autofocus system in video of the canon 5d mk IV must be stopped from the function:
Servo AF in video ON a pause. it can be deactivated from the menu or from the screen on the left side below. with the official dji cable supplied for the canon, we place it so that the ronin s acts on the canon 5d mk IV. As soon as Servo AF is paused, the dji focus automatically starts to work on the lenses, in my case the ART sigma lenses.
Up to here everything seems correct, but I find an important lack in the wheel of focus.
I do not know if it is by ignorance or because this function does not exist, but in the app of android to control the adjustment of our ronin s does not appear any option to control the focus.
I think the speed of rotation with respect to the movement of the focus of the lens is very slow.
I mean, you have to rotate a lot of turns to get the focus from a foreground to a background plane.
I think there are moments when the wheel should be able to act on the path of the lens over half a turn to have a quick manual focus.
I think it should be something similar to what aputure offered with its V-GRIP VG-1, this was compatible with canon 5d II, you could control the focus manually by pressing two buttons front and back. But I had three levels of speed 1, 2, 3. in the ronin app s would be interesting a section for the focusing wheel. just as for the movements of the Joysticks we have low, medium, high and custom, it would be very interesting this option to precisely control the speed of focus. many times we want very slow and smooth movements, but other times we want to focus manually very quickly. I really find it curious that the original focus design didn't take this important detail into account, for example a quick button to switch to a different focus speed mode. But that's no longer possible. At least to have it inside the app would be very important.
