The Mavic Air was announced on 23 January 2018, for release on 28 January. It is marketed as a smartphone-sized drone that can fit in a jacket pocket.
It features a 12 MP 4K HDR camera, mounted on a 3-axis gimbal, and has a new panorama mode, which stitches together 25 photos in eight seconds to create a "Sphere Panorama". Due to antennas mounted on its landing gear, the drone has a 21-minute flight time and a 2.5 mile range. Like the Spark, the Air also features the "Smart Capture" mode, in which the drone can be controlled by hand gestures.
The Spreading Wings (筋斗云) series are mainly industrial UAVs for professional aerial photography, high definition 3D mapping, ultra light search and rescue, and surveillance etc. based on camera gear on board. In 2013, two models have been released: S800 regular and EVO.

The Matrice (经纬) series are designed for industrial applications.
The Matrice 100 is a fully programmable and customizable drone, launched on July 6, 2015. It has expansion bay and communication ports, which allows developers to add additional components for different purposes. 
Matrice 200 series is a range of weatherproof quadcopters from DJI announced in February 2017.
They are designed for industrial applications, including surveying, inspection, search and rescue and firefighting.
The Matrice 200 only supports a single camera, mounted either below or above the drone.
The Matrice 210 and 210 RTK add the ability to dual mount cameras to the drone, allowing multiple sensors to be used simultaneously.
Released in May 2017, the Spark (晓) was designed to be an affordable consumer drone that is nevertheless capable of producing high-quality images and video. This drone is DJI's cheapest to date and features a 12-megapixel camera capable of shooting 1080p video at 30fps. The camera is stabilised mechanically by a 2-axis gimbal. The Spark also carries an advanced infrared 3D camera that helps the drone to detect obstacles in front of it, as well as facilitating hand-gesture control—a feature that was, until the release of the Mavic Air in January 2018, unique to the Spark. In addition to a smartphone app with virtual controller, a physical controller can also be bought, extending the drone's range up to 1.2 miles (2 km). The aircraft has a flight duration of up to 16 minutes, but its exhausted battery can easily be swapped out for a charged battery to extend flight time.
The Osmo (灵眸) is a camcorder developed by DJI. The camera uses a smartphone to view camera footage and can record 4K and take either 12–16 MP stills. The camera is interchangeable, with the Zenmuse X3, X3 Zoom, X5, and X5R gimbals compatible, and uses the FM-15 Flexi microphone.
Similar to the Osmo, it instead relies on the user's smartphone as the camera. Most smartphones are accepted into the gimbal with a width range of 2.31–3.34 inch (58.6-84.8 mm).
The DJI Goggles  are comfortable goggles designed for FPV flying with DJI products. They combine a pair of screens, wireless connectivity, and direct control of photo and video capture. In November 2017, DJI presented a new, so-called 'Racing Edition' .
As of March 2017, DJI has a 50 percent market share of the consumer drone market according to NPD numbers. Top line estimates from the FAA point towards the number of consumer drones hitting over 4 million units by 2021.
In January 2015, a DJI Phantom 3 crashed into the White House's south lawn, in Washington, D.C.. DJI later set up a no-fly Geo-system according to prohibited airspace, and forced all drones to update the firmware. The new system will forbid flights getting closer or take off in restricted zones based on its GPS location.
Several military organizations also utilize DJI products for aerial photography mission including the US Army, and DJI drones were the most widely used commercial unmanned aerial system that the US Army has employed. However, on August 2017, the United States Army published internal guidance regarding the banning of using DJI drones and parts in the army for security reasons. DJI’s Public Relations Manager, Michael Perry expressed surprise and disappointment after the memo was released. A U.S. Army spokesperson responses to media and claim that the guidance is still undergoing a review. Although US Army has stopped using DJI products, other branches of the US military such as the US Marines are still fielding DJI product as commercial photography platform.
On November 17, 2017, Ars Technica reported a security breach of private customer data at DJI. However, The Verge found that according to US government report, DJI drone has kept data safe despite the Ars Technica's claim. Nevertheless, DJI announced they've added Local Data Mode for their drones, which aerial platform will not enable any data transfer involving Internet during the flight. Brendan Schulman from DJI’s Vice President of Policy and Legal Affairrs, responded to the report from Ars Technica, saying “DJI is committed to protecting the privacy of its customers’ photos, videos and flight logs."
