Vol.160 falling from the sky DJI's "swan camera" ~ the new dimension of DJI Ronin4D-guided cinema camera [OnGoing Re:View]

Moreover, the mount can be used by replacing the DJI DL mount and the Leica M mount with the Sony e -mount and mount, and the e -mount electronic contact can be read.It is also possible to add XLR terminals in a form that adds between the battery module like RED.

Arri/RED/BLACKMAGICDESIGN/SONY/CANON The good points of cinema cameras that are used around the world are combined, and this Ronin 4D is united with Ronin.I think each manufacturer is doing various marketing, but usually the marketing voice is rarely reflected due to the creator.

It is amazing that the requests that have been sucked up from the site side are reflected in the product.I was impressed after a long time when I made this much.

The limit is immediately reached, "packing the functions in the specified box," but I would like to express my sincere respect for DJI that "created a box that can accept the function you want to pack."

The sensor has a full frame 6K / 8K model, and this demo machine is a 6K model.It is up to 60p at 6K, but it is possible to shoot 120p HS by 4K by setting SUPER35mm mode and SLO (slow) mode.Kata and 8K are up to 75fps.SUPER35 in crop mode 5.5K shooting is possible (however, HS shooting is not possible in this crop mode).Since it can be selected according to the application, it seems better to consider it as a basic thing.

As mentioned earlier, 9stop (0).3-2.It is wonderful that the variable ND filter of 7) is also built in.It is 14 + STOP's dynamic range, Dual Native ISO (800/5000).This is a 6K camera, and in the case of a 8K camera, it is (800/4000).In both cases, it is possible to shoot with low illuminance

The lens mount is DL, M, and E mount.The DL mount is a type that turns the mounting side like a PL lens and fixes the other mount.Those who do not have an electronic contact, such as the M mount, use LIDAR and lens gear motors to make AF (described later).

Press and hold the button for the camera power supply.The side of the body is very simple.You can switch between gimbal ON/OFF and gimbal follow mode.Equipped with a gimbal resent button.Gimbal can be controlled without a side handle.By pressing the 4D button, the focus can be controlled by the multi -wheel that adds the Z axis to the gimbal control (described later).

By attaching a dedicated adapter to the CFEXPRESS card slot at the bottom of the body side, the Prosd card can be used.By using DJI Prosd (1TB), it is possible to recording Prores Raw or in 4K120P shooting (SUPER35mm mode).

AF control with Lidar

Again, the Ronin 4D lens mount is DL/M/E.Since it was a cinema camera, I did not expect much about AF performance, but Ronin 4D can operate AF.However, since the contrast AF has been abolished and all AF control is entrusted to Lidar, AF operations are not possible even with AF -possible lenses without LIDAR.

It may not be very familiar itself, but the initials of "Light Detection and Ranging" are irradiated with laser light and measure the distance and direction from time to object to hit the object and bounce., Remote sensing technology using light.

This system is mounted on a lens, connected to Ronin4D (also power supply) with the attached USB-C cable, calibration for each lens, and uses the calibration data to control AF.As an image, the 3D focus is powered up, and AF operations can be performed by attaching focus gear with MF lenses.

This is probably difficult at first glance, but once you try it, it's not so difficult.Just because it is an unfamiliar system, there is a possibility that you will struggle to get the location, situations measured with LIDAR, and to grasp the tips for so -called measurement.Lens calibration data can be stored with a name for each lens.

Must -see: Lens calibration method using Lidar

The lens calibration using Lidar is as follows.DJI said it was easy if you grasped the tips, but it might be difficult to recognize that you can grasp the tips or that kind of thing (my experience).

By the way, even if you do not put it on a tripod, it was okay to shoot only the inf, and the front is approaching the wall and setting it.It is an image of calibration, but it seems that it is not a problem rather than that.

I captured the flow of a series of FOCUS CALIBRATION with Ninja V

I want to share it because there are several calibration points.

Try AF operation with e mount

Aside from that, I usually use Sony cameras and have many E -mount lenses.This time, we used the E -mount single focus lens at the E -mount unit under development (it seems to be supported by the time of release).

Not bad from the conclusion.In the Zeiss's Batis series, 18/25/85/135mm was not recognized only 40mm.He recognized the GM50mm (the operation with other lenses is unknown because the GM single focus is only 50mm).At present, the zoom lens does not work.It feels like moving only a single focus.

However, it is speculated that defects will be resolved in the future due to firmware updates.At first glance, it tends to be negative that AF cannot be used unless you use LIDAR, but if you return the opposite, you can exchange LIDAR in the future.You might also say that.It may be that the user perceives (thinking) must also change flexibly according to the camera.

For the time being, the results of the calibration Sony GM50mm have been made into a video, so I want you to watch it.I had the model (familiar Harunono @TEDDY_HARU) move around the tree freely and followed by hand.Of course, I didn't think the AF would work so much, as well as the integrated gimbal.

If it is in the range of about 6m, which is the distance range of LIDAR outdoors, it will capture the subject quite accurately.If it is a project that directs and shoots to some extent, this AF will be a great help in shooting.

Ronin 4D + SONY FE 50mm F1.2 GM AF Test

Goodbye, heavy Ronin

In recent years, electronic-controlled gimbal-type gimbal brands Ronin, SLR cameras, etc. are operated by small gimbals such as Ronin-RS2, and large cinema cameras are Ronin-2, but DJI is DJI.I have broken myself.That is the Ronin 4D of "Camera with built -in gimbal".In addition to the 3 -axis, the performance of this camera, which also controlled the "Z -axis", which is the fourth axis, was tested using AF with an E -mount lens.

The test with a wide -angle lens is not really interesting, so I omitted it this time, and is a 50mm/85mm/135mm medium telephoto (85mm and 135mm are Zeiss Batis).I tried the classic gimbal work, such as pulling, chasing, parallel running, rotation, etc. by hand (I would like to see the video, including the test material of the remote control described below).

Ronin 4D Gimbal Test

Test at 50mm.The 4D mode, which is the name "Shimura", which compares the no correction of 4D mode (Z -axis) with the pulling, parallel, run -up, and rotating movement, promises stability.If there is no 4D mode, a small thrust at the time of travel will still appear.As expected, it is "Shimura".

Next, I changed the model to change to BATIS135mm.As you know, the more the telephoto becomes, the bigger the camera blur.However, the 4D mode of Ronin 4D is cut there.As expected, it is "Shimura" (repeatedly rude).

Because it is a very disadvantageous condition, you may feel some small thrust, but the convenience of 4D mode was outstanding (see video).Thinking calmly, you can take a camera with a 135mm lens with your best or stabilizer.I could only say that it was amazing.

Furthermore, I took a rotating shooting around the outer periphery of the model with Batis85mm.AF can be used in the LIDAR distance range outdoors, so there is a considerable advantage.Again, this is just moving with the camera itself.The paintings to be drawn are also beautiful (see this too).While shooting, I lost my confidence to keep up with the future.

Remote preview remote control

The Ronin 4D is built -in and has a video transmission device.Fly the video without delay (experience) on the monitor sold separately, and attach the camera side handle to both sides of the monitor.

It is possible not only to control the camera and control the camera remotely, but also to send it in manual.Cinema cameras can now divide the camera Opelate and the gimbal (drone) operation with drones such as Inspire.

Now that previews with wireless transmission have become commonplace, it can be previewed without relying on external devices, and even focus can be operated.This is incredibly useful.And it is easy to operate.Surely some manufacturers will imitate this.In recent years, more revolutions will occur on site.

HS shooting and aspect change in the frame rate are a little habit

Ronin 4D can shoot 4K120P HS shooting.However, there is a little habit.First, change the sensor size to Super35mm and set the frame rate to 24p (23).It seems useless if you choose 97.It is unknown for some reason), and it can be selected for the first time by activating the "SLO", "SLO" at the bottom of the selection item.

Note that if you do not activate SLOs, you can only shoot at a maximum of 60 frames.

And the aspect of this camera is 17: 9 and not 16: 9.And in the 60fps 60fps with a full frame of 6K/4K, it can be taken at 17: 9, which becomes a horizontally long aspect of 2: 39: 1, up to 48fps.It is an impression that it is a camera that is conscious of film production because it is a cinema camera.It is also necessary to know that the aspect ratio changes depending on the selected resolution and frame rate.

I also took HS shooting at 4K 120p (see video here too).Speaking of HS, it is a windy backlit sea (my own discretion).I had a model walk in the sea, which is a little windy and the waves with high waves.You will also feel the size of the dynamic range of this camera.This reference video is SDR, but if it is HDR, it will draw a very beautiful picture even if it is no -grade.

DJI Ronin4d 4K120P HS TEST

The lens is SONY FE 50mm F1.2 GM with AF.In such a large place, I tended to exceed the limit of the distance distance, and I felt the limits of the AF of the LIDAR measurement.However, since the manual focus is easy to operate, I thought it would be better to associate with this camera in mind that it was a basic "cinema camera".

High sensitivity is also handy

As I mentioned at the beginning, Ronin 4D is equipped with a dual native ISO and has a low sensitivity of 800.The high sensitivity is 5000.If it is included in RAW, noise reduction will be processed in the post, so it will not be comparable, but it is a dual native ISO that the basic noise is the same, so I am glad if you attach it somehow.

Lighting is of course necessary, but being able to shoot with high sensitivity will expand the range of shooting.

"I can do anything" is not versatile

How is it?If you read the reviews so far and watch the video, it is expected that the expectation for Ronin 4D will increase.As I wrote at the beginning, "I wish I could do that kind of thing."

You are likely to make a reservation while looking at the dealer's site, saying, "I can do anything with this."You should be calm in such a case.

Once you have the actual machine, you should look at whether it fits your own use.Of course, if you have enough money, do not stop.This technology should be praised by many people.

Finally, I want to tell you my feeling.As a premise, Ronin 4D is amazing.There is no lie in this review.I witnessed the various functions of this camera and still remember the excitement of my heart.However, for the writer, Ronin 4D felt a little difficult as I touched.

Everything is due to electronic control, so when some trouble occurs, I feel like I can't do something by swinging it (manual) to end it in time for the time being.It may be one of the concerns.

In fact, I don't like the kind of equipment.I am particularly not good at electrical systems.It should be written honestly that I took the time to prepare for shooting, such as calibration and various settings, and felt stressed.

Ronin 4D will be the target of movies and commercial productions.Production and site will need a DJI specialist -like Dit that is familiar with this camera.If you can't get it back in trouble, you'll be worried.

Thanks to the appearance of Ronin 4D, it will be possible to reduce the number of people in large numbers.At least I don't know if it will bring the gospel to a small team or a one -man operation site from the beginning.

If you like the younger generations and equipment that will create the future in the future, you will be able to respond.At least those who are interested in this camera should first touch it.What can be realized on that?It would be nice to face it.In November, Inter Bee 2021 will be held for the first time in two years.It is said that the actual machine will be displayed at the venue.It's a chance.I want you to pick it up and see it.
