Hi, I have a question for you. How is it that my cheap Xiaomi Note 4X ($100) phone takes way better images than my new DJI Spark($680)? Images from Spark are blurry AND oversharpen! It depends on a certain part of an image. Look at the attached image below (taken not from the air but simply from the window). You can see the original image resized and two parts at 100% resolution. You can also download archives with full resolution images here:

The first archive is from Spark, the second is from my cell phone (just to compare the quality). There is no postproduction on these images.

Slow shutter shot of a dark area by a moving/vibrating drone?  Take a sunny landscape shot.  You might just have more processing power available to convert the sensor data on the phone.  I think the processor on the drone is mostly flying the drone.

nope - sorry to disappoint you, but as I mentioned - I took that picture from my window - it is not from the air. It is impossible for the picture to be blurred only on certain parts when the drone is sitting on the window - besides it is a sunny day and the shutter speed is 1/200 (and yes, I can understand shutter speed, aperture, and ISO). It is not just on this picture. Also, about processing image - I can understand that the picture is not e.g. HDR, but common! Fokus? It has nothing to do with image processing!

Hi there. You can actually use your DJI Go application to adjust the camera settings on your spark. Just switch the button to manual settings so for you to be able to adjust it. Go to DJI Go 4 >> click camera settings >> click the first icon on the top left corner >> switch button from auto to manual. Please see the attached image below for reference. Thank you.

Hi, sorry to disappoint you, but I shoot pictures only on Manual settings - so Yes, those pictures were taken with manual settings. Still, I see no point in your advice - there is no setting for focus (not like on mavic) so all I can do is to change shutter speed and ISO and - as I mentioned - it has no effect in this case. It is 1/200s and the drone is sitting on the window! Not in the air, not moving. The picture should be sharp everywhere.

It is impossible for the picture to be blurred only on certain parts when the drone is sitting on the window - besides it is a sunny day and the shutter speed is 1/200 (and yes, I can understand shutter speed, aperture, and ISO). It is not just on this picture. Also, about processing image - I can understand that the picture is not e.g. HDR, but common! Fokus? It has nothing to do with image processing!

Then it isn't motion blur.  However, it is a shadowed picture exposed for the dark areas so not the same as a sunny scene.  Yes, the speed seems fine to avoid motion blur in this case and the camera was mounted/tripod.  

As far as image processing, I will inform Canon and Sony they are wasting time with their dedicated Digic 8 coders.  A cheap drone microprocessor can do the job for them on the side while flying/navigating/maintaining data links.  The sensor reads the light.  The Digic 8 processor assembles the picture.

very funny - where do you see me mentioning DSLRs or mirrorless cameras? But let them know. Please! I compared it with a cheap cell phone. The sensor, in this case, could be similar. And if it is your way of saying "do not expect decent results from cheap drone" than ok. Do not bother replying.

I can give you another example. From one picture taken at 1/1600s different parts of the image has a different focus. Again, on the bottom of that image, it is the worst:


other parts are ok:

Speaking from a landscape photographers point of view, once you get over the quirks of the Sparks camera, and by certainly NOT pixel peeping and expecting everything to be great at 100%+ it's actually quite a capable camera once you get used to it's small foibles.

ok, THANK you. Finally someone sensible. All I wanted to know is, whether it is normal (unfortunately) or I just have a bad one. I have seen similar problems with the Mavic and it usually was a faulty unit.

I've found mine to be very similar, but for a fixed focus, fixed aperture camera, it's perfectly useable.  I'm actually going to send away an image for printing at A3 size to see how it fares up, I'm not expecting great results to be honest, but then I never bought the Spark for it to suddenly become my main camera in my kit.  It's great for small videos or images to post to Social Media and the likes, but as far as photography using the Spark goes, Social Media posts would be the limit for me personally.

if you bought it solely for photography, I think you need either one of the Mavics which are acceptable to a certain point or the P4Pro which has a 'proper' camera on it.

It is true, that on videos the problem is not so visible due to cropping to 1080p - so I notice that on photos only. Thank you for solving my dilemma! I am probably too much of a perfectionist. If only they added a RAW support I would feel content But I'm afraid that is not gonna happen. Thanks.

The amount of sensor data processing power available on the phone is far more than what is available on the Spark.  The processors, and resources put into them by  Canon and Sony, of DSLR's shows how processing power is a large part of the quality of digital photo path.  

I don't think the sensor and lens of the cell phone are better than the drone but it makes up for it in image sensor data processing power that the drone can't provide.

Yes, and I am still saying, that it has nothing to do with focus. Especially, when only left bottom part is out of focus and the rest is more or less ok. Sorry, but IMHO it just has nothing to do with processing.

The Price of the Spark is just like the Price of a Crop Sensor Camera. Crop Sensor DSLR Resolution is not good for Pixel Peeping too, it may give you some Depth of Field, but the Spark gives you a Different Perspective. What do you pretend from a Drone Camera Lens Smaller than a 5c of a Euro, and a Small Onboard Sensor ?

If you are a Perfectionist and need some Extra MegaPixels (Maybe a Good 100 MegaPixel ?) why don't you look at - DJI Drone for Perfectionists ?

If you can Afford the Rolex, you can Afford the Hasselblad.

nice, totally off, but nice. You should know better than to judge people by their avatars. I have chosen a random image - and in this case, it is a skin for an android watch! You are just another person who completely missed the point. Which was "Is my Spark normal or faulty?" And yeah, I was a bit upset about the fact, that a cheapo phone can produce better photos. Big sorry for that...

You get for what you pay Buddy. If you have money you can get another better drone. Don't expect miracle from a $400 Drone.

I both a Tello costing $100, which don't even have a Gimbal, the Video is Horrible, but its fun for Flying. I saw really good work from Pilots using the Spark. Most Images are used in Social Media nowadays not for Billboards or Commercial Adverts or Big Blow Ups.

I work as a Graphics Designer so I do understand your Point. But with that Money you won't start in getting a Professional Output. A Full Frame Camera Body Only to give good results you have to spend over $1500 - $2000 to get a Decent One, and still they have Pros and Cons.

For Professional Grade, buy Professional Grade.

I fly Drones mostly as a Hobby, sometimes Commercially with my MPP. I bought the Spark as a Starter Drone, yet still I find it very capable. Its a matter of Opinion after all. If you are after Pixels and Resolution, the Spark is not made for you mate. Buy some High End Drone.

Let agree to disagree It is not about pixel hunting. It is just strange to have a different focus in different parts of the otherwise focused image. That is all. Never seen that before - on a cell phone or camera.

The lens acts very funny on the spark depending on the light causing many problems. There is no room for cropping an image, so make sure you are happy with your frame before taking a picture.

From all the photos you produced it is quite possible you have a defective camera.
I have not seen anything like that on my processing.
And you cannot compare a phone camera to a drone camera.

Looks normal to me, probably even slightly better than mine, however I've still produced some ok images...

There is no point whatsoever pixel peeping on something that is effectively a 12mp, fixed focus and aperture flying 'camera' you just have to get used to it.  I took me a while to adjust to the IQ considering my main cameras are a pair of 42mp Sony A7rii's!

What you mean by "out of focus" is "lack of sharpness". That threw me off a couple of times since you're talking about a fixed-focus camera.

You might have a point, but I will never enlarge a photo to that extent, so it's too insignificant for me. If I want super big photos, I can shoot panoramas, and guess which crappy, partly out of focus drone does that?
