I have been wanting to know how the MAVIC lens resolution compares to the P4. while I was at it, I also compared it to the Inspire-1 x3, the xStar and the Yuneec Hpro... click through for the video and the results.
The goal was to create a fair comparison of the MAVICpro and the DJI Phantom 4. this turned out to be far more complicated than anticipated. and I ended up spending almost 10 days working on this project. in the end I did get some good solid numbers that give me some understanding how these compare, based on actual imaging system resolution and dynamic range.
Check out the video and look at the images below to follow along.
The comparison is really rather simple, the devil is in the details. this is a matter of reducing errors.
Interestingly the flat part of the MAVIC grey-step-wedge only show up in video and JPG's, the DNG (raw) files did not display the flat part.
What we have in the test is two simple metrics for the lens-sensor combination that tells us a lot about the imaging-system's performance. I would say for photographers the biggest feature is dynamic range.
Im fully aware that a lot can be done to further refine the accuracy of these two tests. however the important part is that all the drones were measured equally, so the tests are consistent and can be used to see the differences between these cameras, the biggest question is not how the cameras ranks, but there could easily be a small inaccuracy in the f.stop or resolution number, just that inaccuracy likely applies to all of them so the ranking will remain the same, just with slightly different values.
BUT there are naturally more to fully knowing all the details about a sensor, some of these I had to skip to reduce the amount of time it took to finish this test. some of the BIG ones would be
LENS FLARE / diffraction
SENSOR NOISE LEVEL a good sensor can have a lot of noice, but typically a good DR also is a pretty clean sensor.
COMPRESSION & Bitrate.. not strictly camera, however the max bitrate is a huge determining factor to how good and how "flexible" the video will be later in editing.
I did shoot the grey-wedges also in RAW. all of the cameras dynamic range improved roughly 1 f.stop in raw.
