DJI Mini 3 Pro review: a small but powerful drone

For the Mini 3 Pro, DJI has completely redesigned its image processing system. The optical unit in the Mini 3 Pro is mounted on a mechanical nacelle stabilized on three axes. It includes a 6.7 mm f / 1.7 (24 mm eq.) Lens based on a 1 / 1.3 inch CMOS sensor (2.4 μm pixels) with dual native ISO capable of taking images in 48 Mpx and movies in 4K at 48/50 or 60 fps. The Mini 3 Pro also has an HDR video mode at 30 fps, as well as a 1080p slow motion mode at 120 fps. The DJI app allows you to work in a fully automatic way or in pro mode with manual control of the recording parameters, both on photos and in video.

On images you can therefore get images in jpeg / raw (DNG) in the highest definition (48 Mpx) in the ratio 4/3, ie 8064 x 6048 px. In video, you can film in the following formats with a maximum bit rate of 150 Mb / s (H.265):

  • 4K: 3840 x 2160 px at 24/25/30/48/50/60 fps
  • 2.7K: 2720 x 1530 px at 24/25/30/48/50/60 fps
  • FHD: 1920 x 1080 px at 24/25/30/48/50/60 fps
  • Slow motion: 1920 x 1080 px at 120 fps

The ISO sensitivity in photo or video varies from 100 to 6400.

Watching our test videos shows the very good image quality produced by the Mini 3 Pro. The stabilization is remarkable, the images very fluid and the colorimetry flattering (sometimes a little too much …). The Mini 3 Pro also offers a D-cine-like mode that gives much more leeway in correction for post-production specialists.

The small sensor on the Mini 3 Pro is not Mavic 3’s and shows its weaknesses in the handling of chroma noise in the dark parts of the image, a phenomenon also observed in some of our images by zooming very strongly on the dark parts. A thorough examination of the images produced in the laboratory should allow us to see more clearly. Finally, we advise you to avoid zoom functions, which are only digital zoom with loss of image quality. Prefer camera movements in movie mode, which are fluid and much more interesting qualitatively.

In pictures, the small sensor on the Mini 3 Pro does not perform miracles, but the service remains very honest with a start of smoothing from 400 ISO. Smoothing is more destructive at 800 ISO, while remaining acceptable, but avoid exceeding 1600 ISO if possible to preserve a small detail in the images. In raw, it will be possible to retain a little more nuance and precision in the recordings, though with much more visible digital noise.

The sensor / optics pair in the DJI Mini 3 Pro delivers detailed images, and the Chinese brand knows how to take advantage of the sensor’s high definition. In the examples below, you can see that the Mini 3 Pro is much more accurate than, for example, the Xiaomi Redmi 9T smartphone, which is also equipped with a 48 Mpx sensor.

We also wanted to compare the newcomer with the DJI Air 2S, which offers a 20 Mpx sensor.

We also resized the image of the Mini 3 Pro to 20MP for easier comparison. In auto mode, the images are finally quite close with an advantage in precision for the Mini 3 Pro, which benefits from an increase in pixels for sampling. The Mini 3 Pro therefore maintains a good image quality, while at the same time providing an always noticeable extra definition.

In 4K recording video mode, the differences between Air 2S and Mini 3 Pro disappear. The precision of the images is the same, despite a different compression (H.265 for Mini 3 Pro and H.264 for Air 2S). We just notice a slightly more marked accentuation on the Air 2S, which makes the image a bit more flattering. In the studio, the Mini 3 Pro therefore meets the specifications with brilliance.
