On August 2, less than 11 months after the previous generation, Dajiang Osmo Action 4 was released. The current saving is 1/1.3 inch sensor (old friend OV48C?), priced at 2598 yuan, and the all-around package is 3298 yuan.
There is an interesting history. Dajiang Osmo Action 3 and GoPro HERO 11 were both released on the evening of September 14, 2022. HERO 11 is 3498 yuan (1/1.9 inch 8:7 sensor), and Action 3 is 2299 yuan (1/1.7 inch 12 million pixel sensor). Although the price difference is 1200, Dajiang seems to feel it is a shame to lose to GoPro. Later, on November 30, Dajiang updated a lot of functions for Action 3.
This year, Dajiang got 1/1.3 inch CMOS at one go. Unless GoPro has 1 inch black technology (even if there is, it is estimated that the accessories cannot be used universally), Osmo Action 4 should be the strongest sports camera in the next year or more.
Because the 1-inch version of Insta360 ONE R (3498 yuan) released in early 2020 has been taken off the shelves. Like Osmo Action 4, it has a unit pixel size of 2.4 μ m, but it has 19 million pixels and a F3.2 aperture (1/3 gear smaller than F2.8).
Specifications
The appearance of Osmo Action 4 (except that the logo number has changed to 4) and its weight have not changed. The battery and accessories are the same as those of the previous generation (except for the ND filter).
70.5x44.2x32.8mm, 145g weight
The bare machine waterproof was increased from 16m to 18m from the previous generation (the strongest bare machine waterproof for sports cameras on sale).
The 1.4 "320x320 front screen and the 1.25" 360x640 rear screen both support touch control full fit LCD with a peak brightness of 800 nits.
The sensor is upgraded to a F2.8 lens with 1/1.3 inch, 12 million pixels, 2.4 μ m equivalent unit pixels and 155 degree field of view (the previous generation was 1/1.7 inch). It should also be an old friend of Dajiang OV48C, which is used by the owners of Dajiang mini 3/3 Pro, Mavic 3 Pro telephoto, Air 3 telephoto and wide-angle, and Xiaomi 10.
It supports up to 4K 120fps, 1080P 240fps video recording, and D-Log M 10bit mode. The nearest focusing distance has increased from 30cm to 40cm.
3 microphone, compatible with Dajiang DJI Mic wireless microphone.
1770mAh battery, 160 minute endurance (1080P 24fps+super stability enhancement+Wi Fi off. The previous generation recorded 160 minutes at 1080P 30fps).
30W fast charging, 80% charging in 18 minutes, and 50 minutes. A multi-function charging box that can charge three batteries. It can be charged to 80% in 56 minutes and fully charged in 59 minutes in an hour.
New features: Open gyroscope data (Good civilization! You can use software such as Gyroflow to increase stability) Manual adjustment of image sharpness and noise reduction intensity 、 GPS Bluetooth remote control support, app LUT with D-Log M, underwater color restoration, etc.
appearance
The package of Osmo Action 4 is surprisingly small and environmentally friendly.
The standard version of RMB 2598 comes with horizontal and vertical racket protection frame, locking screw, quick disassembly adapter and quick charging line.
This is an all-around package, which has a multi-function battery storage box, three cold resistant long endurance batteries, and a 1.5m extension rod.
There are two memory card slots on the cover. How civilized! Let me tell you ↑
This is the battery and charging box inherited from Action 3, 1770mAh.
The use logic of the charging box is similar to that of the charging steward of the Dajiang UAV. Both of them give priority to charging the battery with the highest power, and can also be used as a charging bank to charge other devices (5V 2A).
Quick disconnect adapter and 1.5m telescopic extension rod ↑
Horizontal and vertical racket protection frame ↑
The magnetic force of the quick disconnect adapter is very exaggerated. The horizontal and vertical racket protection frame has specially left a C port for you to charge. I really understand that.
Glass lens protection cover (the only accessory not in common use with the previous generation, and the ND mirror needs to be bought again) ↑
The front and back sides are covered with soft glue, and the middle frame is full of hard glue.
Familiar layout: USB port on the left cover, battery and memory card slot on the right cover, mode/power button on the left, top shutter, and magnetic snap on the bottom.
Osmo Action 4 and GoPro Hero 10 ↑
Osmo Action 4 is shorter and thinner than GoPro The industrial design/workmanship/texture of Action 4/Action 3 is one gear better than that of GoPro.
The nameplate of Action 4 is the only place that is different from the previous generation in appearance (under the "O" of the light emission is the color temperature sensor).
The appearance difference between the two generations is so small that there is no need to worry about leakage when testing: under normal distance, the number on the nameplate cannot be seen clearly in the wheel eye.
Although passers-by can't find that you are using the new 2598 yuan model, the good news is that except for the ND filter (after all, the CMOS has become larger) All accessories are common Dajiang has made four generations of motion cameras, and finally has "universal and compatible". Unless you want to upgrade 1-inch CMOS, you should insist on not changing the mold like GoPro.
As a sports camera, it is ecological for accessories to maintain the appearance And costs We, Shenzhenwan No.1, also voted in favor of it.
Function and system operation
The cold start of Dajiang Osmo Action 4 takes about 5 seconds. It is the most smoothly operated sports camera now, and may not be one of them. The interaction between Dajiang and GoPro has advantages and disadvantages. GoPro should be more Geek and Dajiang has more functions.
Five sets of preset settings can be saved, and which preset/mode can be customized can be switched through QS button. yes TC Timecode (used when multiple cameras are working together). You can choose to name by file or folder. Now Capable of internal sharpening and noise reduction (3 gears for each).
It can be directly connected to the computer USB camera , even mobile phones can be OTG directly (although it is USB 2.0...)
Live streaming Up to 1080P 6Mbps (available on all platforms), you can access dithering, fast hand, Tiger Teeth, WeChat, and 404 tubing/Facebook, or directly use the RTMP protocol (used for live broadcast in station B).
USB powered recording without battery , but the battery will not be charged during recording (it should prevent overheating. Please unplug the battery when you connect it, and it will be cooler)
The cycle recording duration is optional (5 minutes/20 minutes/1 hour/until full), but still No pre recording function (The fisherman cries.).
Analysis of photographic and video specifications
In theory, if OV48C (Xiaomi Image turns over to be the commemorative version of Xiaomi 10), it should have a single frame of HDR video and native ISO.
Dajiang Osmo Action 4 has a special setting: The camera field is set according to 16:9 The 16:9 picture is 4000x2256 (9.02 million pixels), and the 4:3 picture is 3648 × 2736 (9.98 million pixels). The transverse image field of 16:9 mode is larger.
In addition, Osmo Action 4 No HDR photography and HDR video Such "fancy" functions are a pity, It directly follows D-Log M to provide high dynamic range. However, the preview during shooting is the gray chip mode of D-Log (which should be limited by performance and power consumption). You need to install LUT in the app.
It may be restricted by ISP and CMOS (well-known sanctions), Osmo Action 4 The video specification is almost the same as that of the previous generation The maximum 4K 120fps, 2.7K 120fps, 1080P 240fps (there is also a longer longitudinal 4:3 mode, but it will limit 60fps). There is still no 5.3K video recording and 2.7K 240fps on GoPro.
(4K 4:3 mode and 4K 120/100fps, 1080P240/200/120FPS D-Log M、10bit、 Slow motion is in HEVC format)
Video contrast: Big pixels are cool!
Previously, people were disgusted that the sensor of the sports camera was too small to win the super wide angle of the flagship mobile phone. Now the Osmo Action 4 in Dajiang is 1/1.3 inch.
Although the angle of view is far greater than 155 degrees of the mobile phone, it will have a negative impact on the discrimination (the same pixel is divided equally by more scenes).
So this time we find OPPO Find X6 Pro and Xiaomi 13 Ultra to compare, because poor There is no Hero 11. Use the Hero 10 near the price as the baseline.
OPPO Find X6 Pro The flagship strongest ultra wide angle: free-form surface IMX89050 million pixels, 1 μ m, 1/1.56 ", F2.2, equivalent 15mm
Xiaomi 13 Ultra Ultra wide angle is 50 million pixels, MX858, 0.7 μ m, 1/2.51 ", F1.8, equivalent 12mm, 122 degrees.
GoPro Hero 10 It is 23.6 million pixels, 1/2.3 ".
Dajiang Osmo Action 4 It is a F2.8 lens with 1/1.3 inch, 2.4 μ m equivalent unit pixel, 10 million pixels of actual output (4800W, 1.2 μ m sensor) and 155 degree field of view.
Osmo Action 4 Sensor Dimensions 65% larger than 1/1.7 inch of the previous generation , second only to Insta360 ONE R of 1-inch CMOS (F3.2+equivalent 14.4mm, 19 million pixels, 2.4 μ m).
This OV48C is the main camera of Xiaomi 10, Dajiang mini 3/3 Pro, Mavic 3 Pro telephoto, Air 3 telephoto and wide-angle. Cook said that the supply chain management of Dajiang was fierce.
Field of view/cutting comparison of different anti shake levels ↑
Comparison of respective maximum level anti shake (Osmo Action 4 is the second highest horizon correction mode, which can ignore the positive and negative 45 degree tilt)
First, let's talk about the recording quality and anti shake:
Pre Xinjiang The radio is better than GoPro , but this generation has canceled the pointing radio, so there is no more beeping here.
Anti shake: The cutting force of the super stability enhancement+is close to that of the horizon correction, but the horizon correction can cope with a positive and negative 45 degree tilt, which makes the super stability enhancement+mode very awkward.
There is also a gear "horizon stabilization", similar to the permanent horizontal mode of the Shadow Stone Insta360, which ignores all angles of rotation, but will be limited to 1080P (the self timer bar elimination function is limited to 1920x1440). The image quality is too expensive, so it would be better to use it as a fun function.
testing environment
The first level of super stability enhancement+default sharpness+default noise reduction is the best area for Dajiang Osmo Action 4 picture quality and experience. The following tests all use this setting.
Unified maximum vision, GoPro and Dajiang are both first gear anti shake
In daytime and bright light scenes, GoPro Hero 10 is 5.3K 60fps, and other models are 4K 60fps
Light and weak light scenes, unified use of more practical 4K 60fps, Osmo Action 4 to enable automatic low light enhancement
All Basic information of video recording is shown in the figure ↓ ， The highest code rate of GoPro is 100Mbps, Osmo Action 4 is 130Mbps, and Xiaomi 13 Ultra and OPPO Find X6 Pro are both about 62Mbps. The dark light scenes tested did not show "frames stolen".
The 155 degree wide angle of Osmo Action 4 is larger than that of GoPro Hero 10, which is much larger than the super wide angle of two mobile phones.
Action 4 also has a certain degree of distortion correction under the first gear anti shake. Edge distortion control is significantly better than Hero 10, and there is still a gap between Action 4 and small field mobile phones.
The upper right corner is magnified by 200% ↑, and the details on the edge of Hero 10 are deteriorating rapidly. At the corner, Action 4 of 4K video can catch up during the day.
The anti glare effect of Osmo Action 4 is better than that of mobile phones, but Hero 10 is a little stronger.

Osmo Action 4 has automatic low light stabilization (mainly to control the shutter duration, lower the exposure, and reduce the drag shadow), The picture jitter and drag control are the best of several.
Test video (global):
Test video (central magnification 200%):
The actual effect is clear in the video/screenshot.
The white balance and photometry of Osmo Action 4 are OK, especially the photometry of night scene/weak light scene, which is very close to the naked eye. The strongest detail in the daytime is the Find X6 Pro of the small field IMX890, followed by the GoPro Hero 10 with 5.3K videos. The details of Xiaomi 13 Ultra and Osmo Action 4 with huge vision are obviously 1 or 2 gears weaker The image quality of Osmo Action 4 edge is not significantly degraded, and the edge can reverse GoPro Hero 10.
here we are Lights and night scenes, even without magnification, can see the effect of big pixels on the big bottom The details of Osmo Action 4 catch up quickly, and it is obviously better than the other three in weak light.
The night view video of sports camera has such effect unexpectedly, OV48C is awesome!!!
Compared with mobile phones, the weakness of current motion cameras focuses on dynamic range/computing power. Many highlights and dark details cannot be matched with the HDR of mobile phones by D-Log M.
Heating&endurance&charging
We use the next high video recording specification (4K60fps, 4:3, stability increase+, screen off recording) to test:
From 1521, the room temperature is 26 ℃
16 minutes (1537), 55.7 degrees on the back, 49.9 degrees on the front
30 minutes (1551), 54.4 degrees on the back, 62 degrees on the front
46 minutes (1607), 58 degrees on the back, 65.8 degrees on the front
1 hour and 2 minutes (1623), 58.9 degrees on the back, 67.2 degrees on the front
1 hour, 19 minutes (1640), 61 degrees on the back, 68.7 degrees on the front. At this time, the overheat protection is prompted, the screen is forced to shut down for 3 seconds, and the remaining power is 10%
At 1 hour and 22 minutes (1644), the machine was powered off without power.
Streaming saving means: Hot, a little hotter than the previous generation , but no thermal shutdown. Sports cameras are getting hot, and Snapdragon 888 has to recognize it.
High standard video can run for about 1 hour and 20 minutes, Average endurance 。
However, the body and charging box of Osmo Action 4 are both 3 0W fast charge, can be connected to record, can make up for the endurance 。
The actual charging peak exceeds 28W (9.3V 3A), far exceeding GoPro. A 1770mAh battery sports camera can charge faster than the 10000 yuan iPhone. It is not harmful and insulting.
Accessory ecology
During the year, Dajiang made a lot of accessories, such as wrist strap, GPS Bluetooth remote control, car seat bracket, surfing safety sticker kit, road vehicle accessories, mini handlebar clip, mini extension bar, curved surface adhesive base, mouth bite fixing seat, neck hanging bracket, and ND mirror. The magnetic snap can be taken down at any time, and the accessories of traditional sports cameras are really convenient.
Most accessories are priced between 300 and 500 (chest strap 229, magnetic adapter 129, ND mirror 3 pieces 299). High EQ: a little cheaper than GoPro.
Dajiang: Cameras don't make money. They live on accessories.
User: The camera is only a down payment, and various accessories are provided monthly.
summary
Dajiang Osmo Action 4 has greatly upgraded the picture quality, especially the lighting scene and night scene, which can be called an epic upgrade. You can beat the super wide angle of the flagship mobile phone at night, can you believe it? If you plan to use it in the evening, close your eyes and pay more. Except for the 1-inch model that has been discontinued, it is the strongest.
The only price is that it is a little hot and its endurance is slightly weaker than that of the previous generation ， And 300 , this wave is not bad.
Unfortunately, the highest video specification is still 4K 120fps, and the 240fps slow motion is only 1080P.
Dajiang Osmo Action 4 has been relatively satisfactory. In order to protect the ecology of accessories, the next generation should not change the mold. The predictable upgrade point is Add D-Log M internal preview, make a practical HDR recording, increase the recording specification and frame rate, pre recording function, and GPS information Of course, it would be better if 48 million pixel mode could be opened.
Dajiang Osmo Action 4 is priced at 2598 yuan, which is 300 yuan more expensive than the Osmo Action 3 released on September 14, 22. The all-around package is 3298 yuan (the official website first sent 128G memory card and water cup, although memory card is not expensive this year).
Now GoPro Hero10 and Action3 are both in the 2300 price range, while Hero 11 has dropped to 3000. GoPro focuses on the picture details in the daytime, but Action 4 is more sweet in general. After all, the large pixel scheme is more popular in light and weak light scenes. Add in the price difference of 400 yuan and the "free" 30W quick charge. Conclusion: buy an iron GoPro!
