    Taking off from 520m

    Not a Mavic - the footage displays a very typical fisheye effect, not present in any DJI drones since the P2.

    DJI support have advised me that new firmware will be released soon, to fix soft focus :/

    Well, f/2.2 would give a very shallow depth-of-field on a full frame camera, but since the sensor of the Mavic is so tiny, it is much wider. However, the trees in the foreground are at least 20-30 meters closer to the camera than the house, so one of them will definitely fall outside the focus...

    Yes, you will need to understand the strengths and weaknesses of the design and use it to your advantage. The example photos in Careljnr's reply above clearly show the difficulties - you can either set the focus on the trees in the foreground, or on the house in the middle - but not both. That...

    Shaky and wavey video

    No, it doesn't look like frame rate errors, that would be more of a judder (skipped frames). This looks more like serious write errors.

    Shaky and wavey video

    I am not sure about this... I have been flying my Phantom in temperatures down to minus 20 C (-4 F) and never encountered any jello effects whatsoever. The body of the drone was too cold to touch with bare hands, but it still worked just beautifully. To my eyes this looks like data write error...

    DJI support have advised me that new firmware will be released soon, to fix soft focus :/

    Yeah ha ha, it sure is! :-) The Mavic is incredibly portable. Your picture is a great example of what I mentioned before, I can clearly see the center being MUCH sharper and having a better rendering than the edges and particularly the corners. If this was my DSLR, I would immediately dial it...

    DJI support have advised me that new firmware will be released soon, to fix soft focus :/

    I have yet to see a photo or a screenshot from a movie that displays a perfect image rendering from the center of the frame to the very edges. Actually given the fairly large fixed aperture (f/2.2) and the size of the camera, some edge blur and purple fringe is quite expected. The latter is...

    I am sorry guys, but that is just bollocks from DJI. Having more than 35 years of experience with cameras and optics, I can clearly see that the Mavic's camera has a center bias, i.e. it is optimized for sharpness and detail rendition in the center of the frame. As you move closer to the edges...

    Another video quality moan thread

    The compression artefacts in the Mavic are much more pronounced than in the Phantom 4. The sharpness in the center of the frame is really nice, but unfortunately gets gradually worse towards the edges of the frame. The outer 20% is pretty awful, definitely in the cheap cell phone camera...

    Thinking about packing it all in.

    Some rules and some regulations, yes, without doubt. Flying inside a control zone near an airport, flying on altitudes where there is GA traffic or low above main roads, flying near prisons and military installations, above crowds, near buildings or above densely populated areas - I understand...

    Video goes blurry and out of focus during recording on its own

    Thank you, I really appreciate your pleasant tone, quite a change from the often pretty snide remarks in such forums! :-) The thing is that while I am really drawn towards the Mavic because of its portability, I am a bit nervous about the image quality. If I get the Mavic and make a single test...

    Video goes blurry and out of focus during recording on its own

    I am really trying to like the Mavic, but I have seen an awful lot of footage on YT with horrible image rendering, specially near the outer 30% of the image. I have more than 30 years of photo experience so I believe I can tell the difference. If that is caused by the inability to remember to...

    Video goes blurry and out of focus during recording on its own

    No, but to keep the same excellent camera as on the P4. I don't really see the point of changing it to something inferior - well, except for maintaining the difference between the various segments (amateur / prosumer / professional). /// Tom

    Video goes blurry and out of focus during recording on its own

    This tap-to-focus feature is probably the worst design decision DJI has ever done. You simply don't know what is in focus until you have landed and check the footage on the computer. /// Tom

    Thinking about packing it all in.

    Don't give in just yet! Mind you, your rules are still better than ours here in Sweden. Here flying a camera equipped drone is now completely forbidden, but I still fly my Phantom and I am currently waiting for my Mavic. I am quite sure that in a few years, even the Swedish socialist government...
