The three members will share their insights with you from five aspects: design philosophy, technology, equipment, ease of use, and information to be delivered.

I. Design Concepts: Respond to Ever-increasing User Demands

Outstanding video shooting design and functionality while meeting the needs of professionals and video enthusiasts.

Q: First of all, what is the background of these high-end features on the AX700?

Junichiro Tamagawa 'Product Planning':

Recently, 4K televisions have become more and more popular, and the widespread use of video editing software has also been continuously expanding, which has caused drastic changes in the entire video shooting environment. Enjoying video shooting as an amateur amateur requires the camera to be superior in performance, easy to operate, and even comparable to professional Models. This means that the line between professionals and amateurs has become blurred. In the past, Sony introduced clearly defined consumer video cameras for the average consumer, and launched professional cameras for television broadcasters and motion picture producers. , Two types of user-selected image products have become 'unbounded'. For example, the alpha series of high-performance digital interchangeable-lens cameras for general consumers is also favored by professional dynamic image makers. So we have now introduced three models. Cameras - XDCAM PXW-Z90 (hereinafter referred to as 'Z90'), NXCAM HXR-NX80 (hereinafter referred to as 'NX80') and Handycam FDR-AX700 (hereinafter referred to as 'AX700') - both professional and hobby in the field of cameras Needs.

The Z90 and NX80 are professional cameras, while the AX700 is a Handycam consumer camera. In fact, these three cameras are the same products, and the image quality performance is almost the same. When it comes to specific differences, the Z90 and NX80 provide for low-angle shooting and easy Carrying handles, and XLR interfaces for professional use. In addition, the Z90 offers another interface to support the XAVC professional format commonly used in the broadcast industry.

Q: What is the AX700 development goal in the Handycam product line?

Junichiro Tamagawa 'Product Planning':

Launched in 2014, the FDR-AX100 (hereafter referred to as 'AX100') is the flagship model of the Handycam series. It supports 4K video recording and high-quality imaging and is therefore highly regarded. Now, the AX700 surpasses its predecessor and will The original high-definition performance and new features combine to increase the value of use. As advanced amateurs explore dynamic video photography in all directions, users report that they would like to have more video shooting fun and be able to The setting changes. In addition, imaging industry practitioners who use Handycam as a professional imaging tool need real professional functionality. We took these opinions and requirements into consideration when developing the AX700.

Nobuhiro Onouchi'Product Design (Project Manager)':

In order to develop the AX700, we created a hybrid team that includes ordinary consumer camera crews and professional camera crew members to push the project forward by this joint team. This team is not just picking members from both groups. It is unprecedented. When we will What kind of team is the ideal team when targeting a professional-quality camera? We discussed this issue several times and came to the conclusion that designers of professional cameras should be selected as key members, drawing on the expertise accumulated by the consumer camera team. Knowledge to meet the development challenge of this new model.

Q: What are the specific requirements for the AX700 model?

Junichiro Tamagawa 'Product Planning':

The most common requirement for AX100 customers is auto focus. We have paid great attention to the auto focus function when developing the AX700. The combination of a 1.0-inch large image sensor and a 4K recording function can capture shallow depth of field images, but this performance requires very precise focusing. Although the subject appears clear during video shooting, when viewing on a large screen of a 4K TV at home, the user is sometimes disappointed with the screen because the subject is not as clear as expected. The camera must accurately lock the subject at any time and place. , because the exciting scene is 'transient.' This sounds very basic performance, but when a rare shooting opportunity arises, customers must be able to capture the subject. This is our primary goal, and it is also our focus on autofocus performance. the reason.

Q: Does the AX700 inherit the other important features of professional cameras?

Nobuhiro Onouchi'Product Design (Project Manager)':

Easy operation is very important for professional users. Previously, the menu structure and operation of Handycam were very different from those of professional machines. The AX700 allows more detailed changes to the settings and focuses on the ease of operation. We have improved the OLED electronic viewfinder ( The resolution of the EVF) and LCD monitor to reduce eye fatigue when viewing images, and the AX700 is equipped with advanced equipment for professional cameras. In addition, we have also adjusted the shape of the handle when developing the AX700. The shooting operation is more stable, and according to the durability standard of professional models, it can be used in harsh environments.

Second, Technology: Fast and Smooth Auto Focus

The autofocus performance of the α interchangeable lens camera confirms the potential of the AX700 in the field of motion picture photography.

Q: Please explain the AX700's autofocus function in detail. How does the developer highlight this feature?

Hitoshi Ueda' Software (AF) Technology':

In the history of the Handycam camcorder, the AX700 was the first to adopt the fast hybrid autofocus system, which has shined on Sony's interchangeable lens alpha series and Cyber-shot portable digital cameras. One of the important functions is the automatic phase detection. Focus and traditional contrast autofocus combine to deliver superior autofocus performance - fast, accurate and stable tracking. Another advantage is that the LCD display can display the camera focus position in the green AF frame.

Junichiro Tamagawa 'Product Planning':

The focus of autofocus during photo shooting is how the camera locks the target object quickly and accurately. However, the process of motion image capture is to convert the out-of-focus image into a focused image for recording motion picture performance. In this case, the fast Focusing does not necessarily guarantee superior motion picture quality. In video production, it is often the intention to use slow and smooth focus to express impressive scenes. In some cases, fast and accurate auto focus is of course important for video capture, but The smooth focus lens and its quality are also critical.

Hitoshi Ueda' Software (AF) Technology':

Autofocus technology combines an image sensor with phase-detection autofocus and a new algorithm developed specifically for motion picture recording to achieve a fast, natural, smooth focus lens. How does the camera switch the current focus to its next target object? Benefits The phase detection autofocus system can predict the target object, and the camera can calculate the appropriate focusing speed in reverse to achieve a smooth focusing dynamic image. Therefore, the AX700 is equipped with seven different focusing speeds.

Q: You mentioned stable high-quality autofocus. Can you provide more details?

Hitoshi Ueda' Software (AF) Technology':

Of course, the stable tracking feature of the subject is another selling point of the AX700. A total of 273 phase detection AF points cover approximately 84% of the autofocus range of the entire image area, and each AF point is calculating the focus object. The fixed point plays a role. Next, the system merges the data from each AF point and identifies the user's target object. In addition, it detects the size and action of the specified object and keeps track of it steadily.

However, it is not always necessary to track the focus. If the user abruptly encounters a new situation, such as when shooting a landscape, the child suddenly jumps to the screen and may be eager to lock the child. In another case, if the target direction of the camera is quickly changed, it may not be required to stabilize. Instead of tracking, one needs to quickly move from one focus object to another. As a result, the AX700 offers a range of sensitivity for autofocus object switching. Users can choose from five sensitivity levels to switch from one object to another – From 'RESPONSIVE' to 'LOCKED ON'. In addition, the camera also offers five levels of AF tracking depth range settings - from 'WIDE' to 'NARROW'. Thanks to these rich customization features, users can use the camera to shoot images as expected.

The newly developed algorithm also plays a key role in judging the focus switch. In addition, highly specialized adjustment skills are required to achieve customization of different settings. As a Sony development team member and individual, I have accumulated a lot of expertise in this area. The new camera incorporates what I think is necessary, as well as some of the ideas I'm working on for autofocus on the focal plane of the alpha interchangeable lens camera. I hope that users will be able to shoot different types of motion pictures using different settings modes. , I repeatedly tested a variety of adjustment mode, and ultimately achieved the desired effect.

Q: So, the AX700 can be used in various shooting environments and meet their needs. What are your suggestions for customers to try this camera?

Hitoshi Ueda' Software (AF) Technology':

In Japan, many camera users take photographs of trains. However, trains can be encountered. When shooting time is limited, it is difficult to capture clear trains by manual focusing, and it is particularly difficult to make train images of 4K quality. , This requires advanced focusing technology. In this shooting scene, the AX700 offers fast hybrid autofocus for high quality results. In other scenes, for example, motion pictures are taken in crowded places full of complex movements, stable Autofocus settings are helpful for shooting.

Third, equipment: more gorgeous 4K motion image

The advantage of Sony is that the main equipment is developed on its own. This allows us to easily provide a solution portfolio and technology matching.

Q: The fast-mix autofocus achieves sharp focus and maximizes the 4K picture quality. Now, can you explain the selling point of 4K motion pictures?

Nobuhiro Onouchi'Product Design (Project Manager)':

The AX700 uses a 1.0-inch stacked Exmor RS CMOS sensor. The image sensor is designed as a layered (stacked) circuit structure that can perform high-speed signal processing and pixel processing at different levels to achieve rapid data readout. Helps to improve image quality, but also suppresses image distortion caused by the rolling shutter phenomenon.

This Exmor RS CMOS sensor combines with the BIONZ X high-speed image processing engine for natural tone and texture performance; the ZEISS Vario Sonnar T* lens, including Sony's proprietary thin AA (advanced aspherical) lens, delivers high performance for corner-focus performance It also includes a self-developed algorithm to provide superior high-quality motion images. The internal development of the Sony team is very familiar with the four pillars of image sensor, image processor, lens unit and algorithm. This is exactly what Sony The advantage lies.

Junichiro Tamagawa 'Product Planning':

The AX700 is equipped with a further improved BIONZ X. The image engine is equipped with a front-end LSI that supports optimized image processing, while the system is newly tuned for the AX700 to further increase the processing speed and image quality. The BIONZ X is only for Sony's High-end digital camera products, including the high-end model of the interchangeable lens alpha series and the RX series Cyber-shot for still images.

Q: Can 4K HDR (hereafter called 'HDR') fully demonstrate 4K motion pictures now?

Junichiro Tamagawa 'Product Planning':

First of all, you may want to know what HDR is. In short, HDR can provide images that are similar to human reality perception. Compared with traditional TVs, this technology can display finer, wider dynamic range. Refers to the image resolution, but also contains various elements. We explore HDR, pursue rich color gamut and color reproduction, ideal grades from prominent areas to shadow areas, and exquisite overall images.

Appreciating HDR motion pictures requires HDR-compatible TVs. The market for HDR-compatible 4K TVs is rapidly increasing. To cater to this growing market, we decided to create a motion picture shooting environment that allows users to create HDR motion pictures. And immediately enjoy HDR quality on HDR-compatible TVs without the need for complicated editing. Sony has released HDR-compliant professional video cameras. The AX700 uses this expertise. In fact, members of the professional camera team join The development of the AX700 is a big advantage for us. We hope that users of the AX700 can use Sony's BRAVIA TV compatible with 4K HDR to watch their own motion picture works and fully experience the beauty of 4K HDR video on the big screen.

Note: To display HDR video, the user can use the USB cable to connect the AX700 to an HDR (HLG) compatible Sony TV. When connecting with an HDMI cable, additional TV settings are required.

Fourth, ease of use: professional style

Convenient menu and accessory design to help users quickly and easily select and use features.

Q: In addition to providing excellent image quality and diverse image performance, how does Sony help users more actively engage in motion picture photography?

Junichiro Tamagawa 'Product Planning':

Currently, there are many ways to shoot video. However, because the AX700 is a video camera, it provides excellent operating comfort for taking motion pictures. Our goal is to make the AX700 an ideal choice for easy operation. We believe this is also a Sony user's expect.

Nobuhiro Onouchi'Product Design (Project Manager)':

Therefore, we strive to allow users to enjoy the sense of operation as if they are part of their own body. The AX700 is designed to allow users to easily capture images. In keeping with this concept, we use clever designs, including the weight balance when the user holds the camera. Sense, button ease of use, and menu ease of use. For example, the AX700 is slightly larger than the AX100. It uses a larger handle design, which is common in professional camcorders and provides professional convenience. For example, Users can hold the camera firmly and finely adjust the zoom speed. In addition, the lens zoom ring and the finger of the good match allows the user to achieve precise operation. I hope the user can pay attention to this subtle change.

Junichiro Tamagawa 'Product Planning':

Consumers often take the time to compare specifications when choosing such products, and we not only pay attention to the actual specifications, but also pay attention to the feelings when using the products. We sincerely hope that users can comfortably make videos and shoot them whole-heartedly. For example, EVF and The accuracy of the LCD display has been improved to reliably see if the subject is in focus and it is easy to perform setup changes and shooting operations. We have already mentioned that the resolution of EVF and LCD displays has improved, and pointed out that the green box indicates phase detection Focus area of ​​the AF sensor. Since these green indicators are displayed exactly at the desired focus point, they may be distracting if they move around the object and flash. This is why we repeatedly discuss the number of these indicator boxes. And colors, including software team members, designers, and then determine the satisfactory design.

Nobuhiro Onouchi'Product Design (Project Manager)':

The accuracy of the peak function is significantly improved. This function is used to display the focus area when shooting in the manual focus mode. We have re-examined the system so that the focus area can be clearly displayed. When shooting high-resolution 4K video, it can also accurately focus manually. Believe that users will be satisfied with this. This advantage is due to the increased resolution of EVF and LCD display.

The design adds a lot of high-performance equipment that rivals professional camcorders. For example, EVF and LCD displays hope to meet users' high expectations. Cost-effectiveness is one of the main attractions of the AX700.

Junichiro Tamagawa 'Product Planning':

In addition, in response to user feedback from the AX100, we have equipped the AX700 with a number of convenient functions for shooting motion pictures, including zoom button increments, and dual card slots that allow users to simultaneously insert two SD cards.

Q: There are many changes to the UI menu, right?

Nobuhiro Onouchi'Product Design (Project Manager)':

The number of menu items is greatly increased. However, if the menu becomes too complicated, this 'improvement' is meaningless. This is why we have placed six assignable buttons on the body so that users can quickly access and use the device. Required functions. It can be set in advance, and the common menu items can be selected from more than 40 options.

If the 'direct menu' is set on one of the assignable buttons, the user can control and adjust the aperture value, ISO sensitivity, and shutter speed through the cross key operation. In addition, this adjustment can be done only with the right hand. Left hand to perform other tasks.

Hitoshi Ueda' Software (AF) Technology':

When the outdoor shooting site is too bright to see the LCD screen, it is recommended to use the EVF and cross keys combination, the operation is very convenient.

Junichiro Tamagawa 'Product Planning':

There is also an advantage. When the menu window is displayed on the LCD screen, it does not completely cover the screen. Many professional users do not like the subject being photographed to be blocked. This UI design reflects the opinions of customers with professional camera experience.

V. Passed Information: Play Creative

There are many ways to produce engaging dynamic images. We hope the AX700 will attract more users.

Q: Please talk about slow and fast motion 1 and super slow motion 2 shooting function how to expand the video range.

Junichiro Tamagawa 'Product Planning':

In various ways of shooting motion pictures, the AX700 offers two special 'time' performance modes. One of the features benefits from the Exmor RS CMOS sensor, which is ultra-slow-motion mode, and it can operate at 1000 fps (PAL mode). Speed ​​recording images. Therefore, the AX700 can shoot up to 40 times slow motion video, this feature was only available in expensive professional cameras a few years ago. Another feature is the slow motion and fast motion mode, which allows the user at 100 fps ( PAL mode) Choose a frame rate within 1 fps. Slow motion technology is common on TV and is not new to the general public. In addition, fast motion shooting technology can connect a set of still images taken at time intervals. Produced as a fast-moving motion picture. The camera captures interesting moments with each shot. Hope everyone likes this effect.

1 Cannot record. To record in slow motion and fast motion, use UHS-I (U3) SDHC/SDXC memory card.

2 Super Slow Motion Cannot record 4K images or recordings. SDHC/SDXC memory cards of level 10 or above are required.

Q: I've heard that the market goal of the AX700 is not a specific gender or family, but a user who is very picky about video shooting. Please give these video enthusiasts some advice.

Junichiro Tamagawa 'Product Planning':

Recently, professionals and ordinary users are keen to shoot motion pictures and create creative videos. Now, they can publish their works through social networks and share them with people all over the world. It is imaginable that these video producers (including the AX700 to take action) How do video users enjoy video shooting and production? That's why I keep in mind these enthusiastic users' expectations and continue to develop products. Please enjoy displaying and sharing dynamic images shot by the AX700. I'm looking forward to seeing beautiful works made with autofocus effects. .

Hitoshi Ueda' Software (AF) Technology':

I have encountered many challenges in developing fast hybrid autofocus. The good news is that the AX700 incorporates numerous technical advantages and highly recommended features. The AX700 inherits the fine tradition of Handycam, allowing users to easily shoot without changing the default settings. Outstanding motion picture. The outstanding advantage of this camcorder is its customizability. It can meet various needs like professional camcorders and expand the shooting freedom. We hope users can make full use of flexible settings in different shooting environments as needed. I believe The more you use this camera, the more you like it.

Nobuhiro Onouchi'Product Design (Project Manager)':

The AX700 is a camera innovation and is worthy of the name of the Handycam flagship model. Through meticulous design, it helps professionals and amateur users to capture their dreams. We hope more users can choose, touch, feel it, and exert their performance potential in shooting. This camera will surely bring smooth, superior motion images to users.
