Never before experienced out of focus and ATTI mode

[bergf]

Hello,

I have used the Phantom since a few years back, and the Mavic Pro since November, and I've never had any issues with either.

Today, when flying the Mavic in great conditions (sunny, around 38F), two strange things happened.

1. After a few minutes of flying, the Mavic entered ATTI mode, although there were a lot of satellites available (as seen in screenshot). It kept going in between ATTI and GPS. At some point, it only had Vision.

2. Taking pictures worked to begin with, but after a while, the picture was very blurry, and regardless of altitude or proximity to an object, it was impossible to focus (see screenshots). When landing, the picture became sharp again the second the engines turned off. I could then take off again, with sharp image for a while, until the issue repeated itself.

Has anyone experienced similar issues? Ideas on the cause or how to solve it?

With ATTI I had it several times, mainly where it was some gusts of wind. calibrating IMU after FW update seem to help in my case. Out of focus it happened to me as well but mainly in poor lighting conditions,

The out of focus is not related to ATTI mode. It is a bug in the focusing where once it is off, it stays off by a fixed amount. I've seen it on 2 different Mavic's I've owned. To fix it mid flight, flip over to manual focus and move the focus wheel until the image is in focus. Flip it back to auto focus and auto focus will work correctly after.
