Yes, I am more than willing to do testing as I really want this to work. Please PM me.

As for the other shots being out of focus, I wouldn't rule out some vibrations. The sample  IMG_1270 did not have any vibrations as the quad was in my hand before takeoff.

Can you check the logs in the Pixhawk from that last flight to see the vibration levels? e.g. AccX and AccY should be between -3 and +3 and AccZ between -15 to -5.

So, what are you using as a flight controller hardware?

I'm kind of curious about where you found those acceleration thresholds?  And if anyone has correlated them to how the affect the Canon lens mounting mechanisms? 

Even if the Pixhawk sees those levels, the level of vibration seen by the camera will be less if there is a halfway decent vibration mount.

There was a link to that information in the original post, but here is again.

I checked the plane log from this weekend. Vibrations look like they are in the normal range. See attached. I balanced the props recently. The camera is mounted the plane shown.

See this thread : use of propcase MIN_AV when the camera inserts its ND filter

I attached an updated build for the sx610hs on the porting thread, but I can't test it myself.  You should also delete the test kap_uav.lua script that I sent you and revert to v3.8 for now.

I tested the 4.0b7 today in the plane. It looks pretty good to me. Samples and log and be downloaded here.  https://inet.idealab.com/dbd/1D721D14/kap_uav4.0b7_log_and_samples_2_3_2019.zip

I will download the new port and go back to 3.8 and see how it does next weekend. Thanks again for all the help!

Thanks for doing that. 

Unfortunately, what I did with that version is hack around the incorrect information returned by the sx610 100a port from incorrectly assigned property case variable. So it will only work for the defective port - its not something I'll be making publicly available.
