When DJI announced that the Osmo Pocket 4P could capture an astonishing 17 stops of dynamic range on its wide camera, more than a few eyebrows went up in the filmmaking community. Those kinds of numbers have traditionally belonged to six-figure cinema cameras, not pocket-sized gimbals aimed at consumers. So when the team at CineD ran the device through their rigorous lab testing procedure, expectations were understandably tempered. After all, most cameras that arrive with bold manufacturer claims tend to land somewhere between 11.5 and 12.5 stops in real-world testing — respectable figures, but rarely groundbreaking.
What happened next was genuinely surprising. The Osmo Pocket 4P’s 20mm equivalent wide camera, which features a one-inch sensor equipped with something called LOFIC technology — short for lateral overflow integration capacitor — managed to deliver approximately 16 usable stops of dynamic range at a signal-to-noise ratio of two, and an even more remarkable 17.2 stops at a signal-to-noise ratio of one. For context, that edges out the ARRI Alexa 35, long considered the gold standard for dynamic range performance, at roughly one percent of the price. It is simply the best result CineD has ever recorded since they began testing cameras.
Rolling shutter performance tells a slightly more modest story. The wide camera clocked in at 11 milliseconds in D-Log2 mode, holding steady even when bumped up to 60 frames per second. The 60mm equivalent mid-tele camera fared somewhat better at 9.4 milliseconds using the standard D-Log profile. Neither figure is exceptional, and the results help explain why higher frame rates require some form of sensor subsampling in normal shooting modes — true 4K at 200 frames per second would demand a rolling shutter reading closer to five milliseconds.
Interestingly, the mid-tele camera performed much more in line with typical consumer camera expectations, delivering about 11.6 stops at a signal-to-noise ratio of two and just under 13 at a ratio of one. Perfectly solid for a 1.28-inch sensor, but nowhere near what its wider sibling achieved. That gap underscores how significant the LOFIC technology really is — it is not marketing fluff but a genuine engineering advancement that allows the sensor to hold dramatically more highlight information before clipping occurs.
Of course, raw dynamic range numbers only tell part of the story. The exposure latitude test, which pushes a camera’s entire image processing pipeline to its absolute limits by overexposing and underexposing then recovering footage back to a baseline, would ultimately determine whether those headline-grabbing highlights translate into usable images in practice. Early indications suggested the Pocket 4P handled shadow recovery admirably, though testers noted some challenges with their close-proximity studio setup requiring creative flagging solutions to manage chart reflections during measurement.
