Kamera aksi mencecah siling, bolehkah DJI memecahkan angin?

Orang tidak akan pernah membayangkan sepuluh tahun yang lalu bahawa kamera yang boleh merakam video kadar bingkai tinggi 4K, mengambil gambar, kalis air dan kalis habuk, boleh menahan suhu rendah dan tinggi, dan mempunyai prestasi anti-goncang yang baik boleh menjadi "pekat" menjadi Hanya 145g, dan ini betul-betul kategori baru yang sangat hangat di pasaran domestik - kamera aksi.

Sebagai tuan dalam bidang dron, DJI sebenarnya melancarkan Osmo Action seawal 2019 untuk memasuki pasaran kamera aksi. Walau bagaimanapun, memandangkan pasaran kamera aksi awal pada asasnya "dimonopoli" oleh GoPro, kamera aksi DJI tidak membuat banyak percikan dalam pasaran pada masa itu. . Semua telah mencapai jualan dan reputasi yang baik. Data berkaitan menunjukkan bahawa dalam pasaran kamera aksi, bahagian pasaran DJI telah mencapai 40%. Ia boleh dikatakan bahawa ia adalah pemain nombor satu dalam kamera aksi pada masa ini.

Baru-baru ini, menurut berita yang berkaitan, DJI Action 5 Pro sudah pun berada di pasaran Ini juga merupakan produk pertama dalam siri DJI Action dengan akhiran Pro, yang mungkin membawa kejutan dari segi fungsi dan konfigurasi.

Action 5 Pro, penanda aras baharu untuk kamera aksi?

Menurut foto pengintip yang dikeluarkan oleh blogger @OsitaLV, Action 5 Pro adalah hampir sama dari segi penampilan dengan Action 4/3 Cuma bezanya cincin hiasan emas pada bahagian lensa ditukar kepada merah. Mungkin ini Salah satu tanda yang membezakan versi Pro dengan versi biasa.

Foto pengintip juga mendedahkan bahawa Action 5 Pro dilengkapi dengan sudut tontonan 155° F2.8, aperture maksimum penderia kamera Sebagai peminat lama DJI, Xiao Lei dapat melihat sekilas pandang bahawa ini adalah parameter penderia Tindakan 4. Mengapakah dalam generasi baharu versi Pro, penderia kamera yang paling penting masih belum dinaik taraf?

Apatah lagi Pocket, satu lagi barisan produk DJI, telah menggunakan sensor Sony IMX989 dalam produk generasi terbaru. Ya, ia adalah penyumbang terbesar untuk menerajui fotografi telefon mudah alih ke era satu inci Xiaomi 12S Ultra, OPPO Find X6 Pro, vivo X90 Pro+ dan pengimejan utama yang lain semuanya menggunakan penderia Sony IMX989 dan prestasi sebenar belajar.

Tetapi jika anda memikirkannya dengan teliti, anda boleh memahami bahawa walaupun sensor Sony IMX989 mempunyai peningkatan besar dalam kualiti dan resolusi imej penggunaan kuasa dan penjanaan haba juga besar Untuk produk seperti kamera tindakan dengan isipadu yang kecil dan kawasan pelesapan haba, kelemahan memaksa penderia bersaiz besar ialah penjanaan haba meningkat dengan banyak, dan kebarangkalian terhempas dalam tempoh yang lama. -Rakaman jangka lebih besar.

Kedua, penderia IMX989 pasti akan membawa kos yang lebih tinggi Ambil Pocket 3 sendiri sebagai contoh Walaupun bentuk dan kedudukannya tidak konsisten dengan Tindakan 4, perbezaan harga antara keduanya ialah 901 Yuan. untuk memikirkan perbezaan kos dalam penderia kamera. Anda mesti tahu bahawa siri Action asal bergantung pada harga yang cukup berpatutan untuk mengalahkan GoPro Jika harga Action 5 Pro meningkat terlalu banyak, jualan dan reputasinya mungkin terjejas.

Ada sama ada Tindakan 5 Pro akan menambah pelbagai ciri baru dalam video, seperti kualiti imej 6K, kadar bingkai yang lebih tinggi, dan beberapa kali Lei berpendapat kemungkinannya sangat tinggi kerana rakaman gerakan perlahan. Lagipun, jika tiada peningkatan dalam sensor, maka mesti ada peningkatan dalam fungsi dan algoritma Jika tidak, bagaimana DJI berani menamakannya Pro?

Selain itu, media asing mengumumkan bahawa kapasiti bateri Action 5 Pro juga akan ditingkatkan daripada 1770mAh kepada 1950mAh Secara logiknya, prestasi hayat bateri akan dipertingkatkan pada tahap tertentu, tetapi memandangkan Tindakan 5 itu Pro berkemungkinan besar akan menambah beberapa pilihan kualiti imej baharu Dan fungsi, prestasi khususnya tidak akan ditentukan sehingga mesin sebenar dikeluarkan.

Aspek terakhir ialah harga yang paling dibimbangkan oleh semua orang Memandangkan harga semasa kamera aksi adalah antara 2200-2500 yuan, harga Action 5 Pro sepatutnya berada dalam 3000 yuan, tetapi berapakah harganya. menarik pengguna? Jika anda membelinya, anda perlu menunggu pendedahan seterusnya.

Bagaimana lagi kamera aksi boleh menjadi inovatif?

Unlike the field of professional cameras, the target group of action cameras does not put image quality first. After all, action cameras are limited by size, weight and price, and they certainly cannot be compared with large and heavy professional mirrorless cameras. Moreover, 4K resolution video specifications can already meet the needs of more than 95% of users.

Take Xiaolei himself as an example. Except sometimes he is curious to experience how high-definition 4K resolution is and how power-consuming it is, the rest of the time the image quality and frame rate options of his DJI Action 4 are fixed at 1080P. /30 frames. For commonly used social platforms such as WeChat, QQ, and Xiaohongshu, videos of this specification are completely sufficient.

As a category with clear goals, action cameras have many specific situations for which they are most suitable. It tries to streamline unnecessary functions, reduce volume and weight, and stack materials in one direction. Rather than making a bucket model, consumers would rather see a good product with a long board that is "long" enough.

But in Xiao Lei’s view, the action camera market has already entered a technical bottleneck period. In terms of image quality, the Action 3 released last year is still usable today. In terms of functionality, many action cameras have a surplus of functions. . This situation also reminded Xiaolei of today's mobile phone market, which is also struggling with hardware issues and users have already entered a period of fatigue when replacing new phones.

But the mobile phone market has also come up with another interesting point in the past two years: folding screen mobile phones. Their unique shapes have attracted many users to place orders for them. What about action cameras? Can we also learn some experience from the mobile phone market and change the form of the product?

It is actually feasible. For example, the early DJI Action 2 was a very bold attempt. Its shape is different from GoPro. It is not so much an action camera as it is a separate component. Different functions can be realized by connecting with different expansion modules. It can be said that there are many ways to play and full of creativity.

However, due to the immaturity of DJI’s early technology, Action 2’s performance in terms of heat dissipation and battery life is relatively average. It is no wonder that the subsequent Action 3 uses the conventional design again. Now, with the maturity of technology, these manufacturers may be able to pick up this somewhat "retro" but somewhat "innovative" design.

Also, the action camera APP is still not mature enough. Take the DJI Action 4 and Shadowstone Insta 360 X3 used by Xiao Lei as examples. , the APP experience of both can only be described as average. Especially the process of transferring video from the camera to the mobile phone is limited by network bandwidth. Exporting a one-minute video often takes half a minute or more. During this period, you cannot exit the APP interface, otherwise the mobile phone will The connection to the camera will be lost and everything will have to start again.

What’s even more puzzling is that the transmission interface of Action 4 only supports the USB 2.0 transmission protocol, which means that the speed of file transfer using the data cable is even much slower than that of the APP, which is not suitable for those who need to record For people with a large amount of material, exporting videos every time is a particularly painful thing.

Therefore, in addition to improving the operating logic and transmission speed of the APP, action cameras can also consider replacing the current mainstream Mirco SD card slot with an SD card slot, so that users can directly use a high-speed card reader to export material.

The last point is a technical issue. Action cameras are limited by their size and cannot be equipped with more professional mechanical shutters like mirrorless cameras, but electronic shutters use frame-by-frame exposure when shooting. Shooting mode, when shooting some high-speed scenes or slow-motion scenes, there will be an obvious jelly effect, (objects in the image are distorted or tilted) affecting the film yield.

The only solution is to use CMOS with faster reading speed, or equip it with a global shutter with a larger scanning area, but both of these methods will increase the cost of the camera. As for how to solve it, this Let’s leave the problem to the manufacturers.

Written at the end

Action camera has always been a category belonging to a niche group. For the vast majority of users, it is extremely useless and can hardly even be called a real camera. .

But for the entire camera market, the existence of action cameras has greatly enriched the application scenarios of cameras. Now we can hang action cameras on helmets, attach them to cars, and even hang them on drones. Its unique perspective is simply unmatched by traditional cameras.
