I do need to key in focal lenght when switching on the Q.
Well I have only used the Q with telephoto lenses so dont do much hand held.
You could try testing the lens on a tripod at a fixed object to see if it works ok when stable.
If it does ok then try handheld at the fixed object.
Along the way you may find that a certain aperture does best with the lens on the Q.
Then try the airplanes again.
It may turn out that it is not a good fit for that application.
I don't shoot moving objects much with the da*300 or other tele photos on the Q because it is difficult to focus and follow.
