Shulou(Shulou.com)11/24 Report--

It is said that if you go fishing at the age of 30, you will take a detour for 30 years less.

When the author is about to enter the year of "standing", he is inexplicably infatuated with fishing or, more accurately, Luya.

In the past half a year, most of the shores, seaside and some small docks in Qingdao Jiaozhou Bay have been patronized by the author. Go to more times, naturally also know a lot of Luya, according to the author's observation, these Luya in addition to "road" not on the fish, but fishing knowledge is really profound ah! They know everything from lunar phases, tides, sea breezes and topography to the "model", daily life and eating habits of fish. They can be said to know astronomy above and geography below.

In addition, in addition to Luya's extremely extravagant equipment, they also have another feature, that is, they like to hang a whole sports camera around their necks and have a good name for recording "middle fish moments." it's hard to say whether they can add buff to the middle fish rate, but it can really bluff people.

If you have a little bit of mind, you will also edit the video recorded by the motion camera and share it on the short video platform, which can accumulate a lot of fans over a long period of time.

The author has seen a lot, and I will inevitably be tickled with greediness. For myself, it may be very difficult to spend thousands on spinning wheels, but I am very happy to buy a sports camera at the same price. After all, wheels can only fish, but sports cameras can not only be used to record fishing (but also can install X)!

It is also a coincidence that when the author is ready to take a good look at the sports camera, DJI brought its brand-new masterpiece-DJI OSMO ACTION 4.

So by the opportunity of fishing, the author also got this product, and by the way, I also shared a simple experience with you.

First, packaging and accessories start with the outer packaging. The ACTION 4 we got should be the all-round packaging version. The outer packaging looks small, but it still carries a lot of weight in hand. After opening the package, the contents are also full.

In addition to the instructions, the equipment itself and the lens gasket, there is a telescopic selfie rod with a telescopic length of up to 1.5m, as well as accessories such as quick-release adapter * 2, locking bolts and horizontal and vertical frame, flat adhesive base, CtoC PD charger, and the most important cold-resistant battery and battery charging box.

Accessories such as telescopic selfie stick, horizontal and vertical racket protection frame, etc.

DJI ACTION 4 + protection frame + magnetic quick removal adapter + locking bolt + telescopic selfie rod ACTION 4 multi-function charging box supports fast charging, continuing the previous generation design, it can be stuffed into three batteries at the same time to charge, 3 to 80% only 56mins, and each battery will be displayed through the status light.

Cold-resistant long-lasting battery * 3 and battery charging box more importantly, this multi-functional charging box can even be used as a mobile power supply at critical moments, although each battery has only the capacity of 1770mAh, it is also sufficient to emergency charge mobile phones and tablets at critical moments. CTOnews.com has also been measured, and it can charge iPad and other devices with PD3.0 fast charging and 10W specifications.

Boy, it's really "one machine with two uses", which is worthy of the word "multi-function".

Therefore, it is strongly recommended that interested partners should buy an all-around version in one step, because it really adds a lot of points to the convenient shooting experience.

Second, product appearance and interaction design from the previous generation of products, DJI ACTION motion camera returned to the traditional small box shape, DJI ACTION 4 also continued this design, compared with the previous generation of products, the appearance of DJI ACTION 4 does not change much.

A more obvious change in the appearance of ACTION 4 is the word ACTION 4 on the front and bottom, and the number has changed from 3 to 4, which may be the most intuitive way to distinguish between two generations of products.

Among them, the letter "O" in ACTION 4 still uses a hole design, and there is a color temperature sensor inside.

The front of the ACTION 4 machine is a 1.4-inch color screen with a resolution of 320 × 320, which supports touch and is bright enough to be used outdoors without pressure.

In the camera section on one side of the screen, this is the biggest part of the ACTION 4 upgrade-a 1.3-inch oversized sensor with an equivalent size of 2.4 μ m per pixel. ACTION 4 is more expressive in sports scenes and scenes such as high light ratio and night shots, thanks to the blessing of 1Rank 1.3-inch large size sensors, which we will discuss in more detail later.

Other changes are far from "change". It is still a 2.25inch, 360x640 back screen with consistent brightness, 75050 cd / m ², and supports touch control.

The operation logic of the positive and negative screens is basically the same, including sliding and switching shooting, adjusting the shooting details, such as selecting resolution, scale, frame rate, adjusting anti-shake mode, wide angle and so on.

In addition, ACTION 4 also provides a quick slide bar interactively, just like the control bar on your phone, you can make more complex settings, including adjusting screen brightness, turning on voice control, screen rotation locking, locking screen, entering the settings menu, and so on.

Getting started is really zero learning cost, as long as you can use a smartphone, this thing is not difficult.

At the top of the fuselage is a red Snapshot shooting button, which supports one-button recording in the off state, which is a very user-friendly design. Like fishing scenes, you can't keep recording and waiting for the fish to take the bait! So when you feel that there is a fish bite hook, press this button directly, and record the wonderful picture when you turn it on, which not only saves electricity, but also saves the tedious cutting of material in the later stage.

After recording, the device will shut down automatically within 3 seconds, and touching the screen can prevent the shutdown. You can also choose the automatic shutdown time in the settings, which provides options ranging from 30 seconds to 30 minutes to avoid the risk of forgetting to turn off and lose power.

On the left side of the fuselage is a QS button for switching on and off the machine and switching between the preset modes of shooting.

In the system, you can also save the commonly used parameters and shooting mode to the C1 to C5 shortcut keys, and then use the QS button to switch quickly. Simple blind exercises are not a problem at all.

The Snapshot button at the top and the QS button on the side are the only two physical buttons on the fuselage. It is these two physical buttons that can cover most of the shooting scenes. And, turn on, turn off, shoot, stop shooting and so on have different sound effects, you can even voice control, such as neck hanging or wearing on the helmet, you can completely do blind exercises without looking at the screen, through different sound effects to determine the status of the device.

As far as human-computer interaction is concerned, DJI still exists as a king.

Below the QS button is port C, hidden under the waterproof card to support 30W fast charging and data transfer on the other side for installing batteries and SD cards. With DJI logo, the cover plate also uses a push-pull lid design.

Battery and SD are installed independently and do not interfere with each other, which is highly praised. And there is a pull piece on the battery to facilitate the battery to take out, which is also praised for this detail design.

At the bottom of the ACTION 4's fuselage is a huge magnetic device, which is really convenient compared to traditional screws. By the way of magnetism, the quick disassembly adapter (fixed on the selfie stick, hanging neck, elastic belt and adhesive base by bolts) can be firmly attached to the bottom of the fuselage.

Because there are still two clasps, the magnetism of the machine and the adapter is stable, and the hard break is unbreakable, even if you do some large-scale movement, you don't have to worry about the fuselage falling.

At this time, some people may ask, does the magnetic adapter have to be fixed by twisting screws when it is different from the selfie stick? The author had similar doubts at that time, but it was only after I really got started that I found that it was my own pattern-is it necessary to disassemble the magnetic transfer piece and the selfie rod after they are fixed by screws?

The key point is that the installation cost and learning cost of the magnet are extremely low, and you can even disassemble and install in seconds after you have been in use for a long time.

ACTION 4 installation of horizontal and vertical racket protection frame is more critical, with horizontal and vertical racket protection frame, you can also achieve ACTION 4 vertical beat operation, on one side of the horizontal and vertical beat protection frame, there is also the same magnetic design as the bottom of the fuselage, the way of magnet + buckle can make the machine firmly stable on the adapter.

With a protective frame, ACTION 4 can easily achieve vertical beats.

The only regret of the vertical beat operation with the horizontal and vertical beat protection frame is that when the ACTION 4 installs the horizontal and vertical beat protection frame, it is not so convenient to exchange the battery. It is necessary to remove the horizontal and vertical beat protection frame before taking out the battery.

But fortunately, the installation of the horizontal and vertical protection frame is also relatively simple, the buckle design, it is not difficult to get started. On the other hand, this protection frame allows you to quickly realize the vertical shot operation, and also has a certain protective effect on the machine itself.

Therefore, DJI ACTION 4 is very careful in these details, not to mention the video effects, such as magnetism, multi-function charging box, and simple interaction and operation logic, which is enough to score a super high score for the initial impression of DJI ACTION 4.

This is also mentioned by the author above, and it is strongly recommended that small partners who have plans to buy should buy this all-around suit in one step, save the back and then spend a lot of money to upgrade, and spend a lot of time and money (the exception of buying back and planning to eat ash).

3. Video experience Note: all GIF are compressed to a certain extent, which does not represent the real picture quality experience. All test videos are provided at the end of this article (you can also click here to watch).

Most of the functions mentioned above are actually supported and implemented in DJI ACTION 3. The most significant upgrade to the DJI ACTION 4 is the picture quality upgrade to a 1max 1.3 inch sensor.

As for why not use a larger one-inch outsole, after all, the one-inch outsole has become standard for flagship machines. DJI also explained this in the QA before the product release:

Due to the physical limitations of optical depth of field, one-inch cameras are not suitable for panfocal motion cameras. The 1Comp1.3 inch sensor used by OA4 is the best choice for comprehensive dynamic range, dim light performance, pan-focus shooting and lightweight size. At the same time, OA4 not only replaced the 1.3in sensor, but also redesigned the lens module to increase the sensor area while still ensuring the focus distance of the most recent selfie.

Thanks to the advantage of outsole, DJI ACTION 4 has a good upgrade performance in the urban night scene, sunrise, sunset and other high-light scenes. Moreover, under the condition of sufficient light, the picture quality of DJI ACTION 4 is also more outstanding.

Let's directly select a few representative scenarios for experience.

First of all, the sun sets in the west, when the water reflects the afterglow of the setting sun, and the sky and the water form a strong contrast between light and dark. In a scene like this, some small-soled sensor devices are obviously unbearable.

Video dynamic screenshot

Note: the resolution is 2.7K / 60 frame, and the anti-shake mode defaults to super stability enhancement (RS). The performance of DJI ACTION 4 is much more satisfactory, as shown in the following picture (video screenshot), DJI ACTION 4 presents a good dynamic range performance, water surface and light have a certain sense of layering, even if magnified, the far surface ripples retain a lot of details.

In addition, when moving the DJI ACTION 4 lens in this highlight ratio environment, there is no unnatural transition between light and dark, or the phenomenon of over-exposure and underexposure for a long time, and the transition from highlight to dark is very smooth and natural, with a bit of iPhone flavor.

In addition, when shooting some small objects in DJI ACTION 4, such as the following picture, the camera is hanging in front of the chest, and when the author ties the fake bait in front of the lens, DJI ACTION 4 does not lose focus.

When there is plenty of light during the day, the performance of DJI ACTION 4 is even better, with sharp pictures and rich colors. The clouds in the sky, the desert in the distance, and the grass beach nearby all retain a lot of detail.

Dynamic screenshot of 2.7k video

4K video dynamic screenshot in the indoor environment, because the light is not as sufficient as outdoor, but the outsole advantage is still quite obvious.

For example, in the following picture, take the indoor store as an example, under the dim light, there is also a good picture quality effect, the details of the product, the edges of the text are relatively sharp and clear.

Of course, if you zoom in, there are still some smear marks, but as far as the effect is concerned, it is already quite outstanding.

2.7k video dynamic screenshot (indoor, relatively dim light) it is worth mentioning that DJI ACTION 4 also optimizes the D-Log M color mode, which is very important for professional users, similar to the RAW format in shooting, which can retain more dynamic range and further expand the later tone space.

In terms of ultra-wide angle, DJI ACTION 4 can provide a maximum of 155 °super-large FOV, which can capture the scene to the maximum extent.

In the setting, you can also choose according to your own needs, including ultra-wide-angle, wide-angle, standard and narrow modes. However, the number of wide-angle modes supported in different anti-shake modes is not the same.

When talking about anti-shake mode, DJI ACTION 4 provides Super Stability Enhancement (RS), Super Stability Plus (RS+), Horizon Correction (HB) and Horizon Stability Enhancement (HS).

It should be emphasized that not all images support four anti-shake modes. For example, in 4K+120 frame shooting mode, the latter two anti-shake modes are not supported.

In contrast, 2.7K+60 frame quality shooting, all support the above four anti-shake modes, and also ensure a certain picture quality and look and feel, which is also a "cost-effective" choice.

In addition, the wide-angle range of the four anti-shake modes is also different. For example, super stabilization + should have a certain amount of picture clipping than super stabilization, and the same is true for horizon stabilization and horizon correction.

For the average user, you really need to learn what anti-shake mode you want to use in what scene. This is also a rare place that needs serious "learning" on DJI ACTION 4.

Specifically, super stability enhancement and super stability enhancement + are more suitable for sports from the first-person perspective, such as normal walking, trotting, following, and so on.

Super stability enhancement

Super stability enhancement +

Super stabilization + horizon correction eliminates the picture shaking within 45 °of plus or minus 45 °on the basis of ensuring 4K high-resolution picture, which is suitable for some scenes with large left and right sloshing.

For example, the following picture goes up and down the stairs, even when running, the picture still maintains a stable state, and the range of shaking is very small.

Horizon correction, of course, if you are doing more intense exercise and need to keep the picture horizontal all the time, then the stabilization of the horizon is very suitable for you, and the lens will be shot horizontally at any angle, even if you rotate the lens. The picture won't rotate with the lens.

The horizon stabilizes and the lens has been rotated for one week, but the picture remains horizontal all the time.

Turn on the horizon to stabilize, such as playing badminton, such as relatively intense sports, the picture is always horizontal, but also can counteract violent shaking, stable as an old dog, the only regret is that the picture will have a certain cutting, although these four anti-shake modes look a little complicated, the learning cost exists. However, DJI still gives this choice to users, and provides four rich choices, users can choose according to their own needs.

In the evening, in some dim scenes with slightly complex lights, the outsole advantages of DJI ACTION 4 will be shown again, such as the music festival pictured above, where the flickering lights on the stage are not overexposed, ACTION 4 is well suppressed, and the distant sky is relatively pure with no obvious noise.

What needs to be emphasized in the 2.7k night scene is that despite the upgrade, it does not mean that DJI ACTION 4 is really like night vision. In some extremely dim scenes, such as wild fishing, when there is no light and the distant streetlights are subtle, the images recorded by ACTION 4 are basically unavailable, after all, even outsole phones have a very low production rate in this environment.

The advantage of DJI ACTION 4 is that the night scene with lights, or the sky will go dark, and the video footage is quite satisfactory.

Photo taking and more function experience as a motion camera, DJI ACTION 4 also supports taking pictures. Photography also provides wide-angle and ultra-wide-angle modes.

Photo sample: as far as the experience is concerned, the wide-angle view range of DJI ACTION 4 is comparable to that of mobile phones, while DJI's ultra-wide-angle is really "super". Of course, the obvious distortion of the edge is also inevitable.

In general, wide-angle mode can meet the shooting needs.

In terms of color, the sample of DJI ACTION 4 is obviously more gorgeous, the picture saturation is slightly higher, and the color is very pleasing, so it is very suitable for making films in moments.

DJI ACTION 4 also brings slow motion, delayed shooting and other functions, as a motion camera, this is also a necessary function, can make the camera playability at least a few points higher.

Taking time-delay shooting as an example, DJI ACTION 4 provides both static delay and dynamic delay, and also provides options for fixed scenes such as sunrise and sunset, without tedious operation.

Static delay shooting (30x)

Dynamic delay shooting (5X)

Dynamic delay shooting (30x)

In terms of slow motion, DJI ACTION 4 provides two modes: 120fps and 240fps. What is worth mentioning in the picture above is that DJI ACTION 4 also focuses on upgrading its waterproof capability. Compared with the previous generation of bare metal 16m, this upgrade of bare metal 18m waterproof depth is also the strongest in the market.

Thanks to its good dark light shooting performance and accurate color restoration performance, DJI ACTION 4 can also realize underwater color restoration with the help of DJI Mimo app (also supports DJI Mimo App pairing and remote control via mobile phone).

Due to the time reasons, the upgrade points of DJI ACTION 4 will not be mentioned one by one, such as support for open gyroscope data export, image adjustment, GPS Bluetooth remote control & dashboard function, stronger noise reduction ability and so on. We will organize and upload all the above material videos, and interested partners can click on the video link below to learn more.

Finally, there are battery life and heat resistance tests. DJI ACTION 4 has no significant upgrade compared with the previous generation. Official data show that it supports 160min recording time (1080p / 24fps), and the measured CTOnews.com is close to this data.

It must be praised that because DJI ACTION 4 itself supports fast charging, so charging is also extremely fast.

The author's personal experience shows that in the 180-kilometer self-driving tour between Xining and Qinghai, three batteries can basically withstand this distance. Even if the power is out, it can be recharged quickly by fast charging in the car, and dozens of minutes of video recording can be met in a few minutes without having encountered the problem of battery life anxiety.

More importantly, during the self-driving tour, the author kept the DJI ACTION 4 in front of the dashboard for video recording. The light in Xining and Qinghai was extremely strong. Under the condition of direct light and long working hours, the DJI ACTION 4 fuselage did have a very serious fever (so that it was a little hot), but along the way, DJI ACTION 4 never "overheated to death" and kept working. On the contrary, there has only been one case in which the screen is closed due to the heat of the fuselage. This proves that the reliability of DJI ACTION 4 is quite strong at high temperature, which is praised.

Written in the end, the DJI sports camera Osmo Action 4 was officially released on the evening of August 2, with the official price of the standard version at 2598 yuan and the all-around version at 3298 yuan.

In a word, DJI ACTION 4 is still the most valuable sports camera to buy at the moment, especially before the release of competitors'12-generation new products. DJI ACTION 4 inherits the advantages of rich accessories, easy to use, convenient operation and stable picture quality of DJI ACTION 3, and upgrades the sensor to increase the performance in large light ratio and dark light.

If you need a sports camera at this moment, then DJI ACTION 4 must be your inevitable choice. Of course, if you are a third-generation user and don't have much demand for night scene shooting, then the third-generation experience can catch up with fourth-generation users in most scenarios. If you have a higher demand for outsole and dim light picture quality, then don't worry about it and go to DJI ACTION 4!
