There's no shame in using add-ons for mobile photography.

For over a decade, phone makers have been cramming cameras into handsets. Now, they're starting to attach camera components externally, piece by piece.

If you've been following recent trends in mobile imaging, you'll notice that 'add-ons' are taking center stage. Take the vivo XFold6, for instance, with its 200mm extender lens. Or OPPO and Honor, which have introduced magnetic secondary screens for phones, allowing solo shooters to use the rear main camera for selfies, previews, and controls.

When people buy a phone, they often hope to avoid carrying a separate camera. Yet, when they get serious about shooting, out come the lenses, screens, gimbals, wireless microphones, fill lights, and SSDs—turning their phones into increasingly professional setups. Surprisingly, these accessories aren't just for pros. Extender lenses, fill lights, and wireless microphones have become essential for everyday users attending performances.

At Leitech, we believe the next battle in mobile imaging won't abandon lenses entirely. The battlefield has shifted from inside the device to the outside. While sensors and lenses determine the upper limit of image quality, for ordinary people to shoot 'professional' video, they need to enhance both the 'internals' and 'externals.'

Mobile Imaging: Growing External 'Organs'

Let's face it: phones have limitations in thickness and weight. Extreme capabilities with low daily usage frequency are unlikely to reside permanently inside the device. Take ultra-telephoto lenses, for example. Major manufacturers are competing in this space. The vivo X300 Ultra retains a high-frequency 85mm equivalent telephoto lens. When users need to shoot birds, stages, or distant subjects, they can attach a 2.35x or 4.7x Zeiss extender lens, extending the focal range to 200mm or 400mm equivalent. The G2 Ultra weighs 248g, and of course, it's not lightweight when equipped. This represents the division of labor in mobile imaging: commonly used capabilities remain inside the phone, while low-frequency but high-value optical capabilities are installed as needed.

However, these extender lenses don't necessarily mean external attachments always outperform native periscope telephoto lenses. They add weight, and installation precision and optical quality can affect the final image. Low-quality external lenses may introduce vignetting, color shifts, and edge blur. Nevertheless, it's worth noting that phone makers are starting to treat extreme focal lengths as loadable optical plugins, no longer insisting on cramming every possibility into the limited device body.

Unlike 'extenders,' mobile imaging add-ons also include fun and interesting accessories, such as 'selfie screens.' The OPPO Bubble and Honor 600 series' magnetic secondary screens take a different approach. They hardly participate in imaging; their significance lies in allowing solo creators to use the higher-quality rear main camera while still seeing their expressions and movements clearly. Honor even incorporates four levels of fill light into the secondary screen, while OPPO lets the screen serve as wallpaper and an 'electronic badge.' For imaging accessories to appeal to everyday users, they must not only be useful but also lightweight, good-looking, and something people are willing to carry daily.

In the past, manufacturers defined imaging capabilities with lenses and algorithms. Now, a screen that doesn't participate in imaging can also become a selling point. The reason is simple: for solo shooters, if they can't see themselves, even the best main camera is hard to use effectively. The OPPO Bubble doesn't make the main camera parameters stronger; it makes it easier for a person to watch themselves while shooting with the main camera. Nowadays, framing rights and control rights must also be included in the scope of mobile imaging capabilities.

Honor integrates fill light into the magnetic secondary screen, while OPPO's official accessories include a magnetic fill flash. DJI has also created a 10g OM fill light that can be directly attached to a gimbal. While mobile night algorithms can synthesize brighter static images, they can't change the direction of light out of thin air or automatically give skin tones ideal lighting.

The significance of small fill lights isn't to turn night into day; they just need to add a small, controllable amount of real light to faces, food, or close-up subjects. They can be used as soon as they're attached, without separate wiring, often aligning better with mobile usage habits than pursuing extreme brightness.

Of course, when it comes to mobile imaging accessories, handheld gimbals must be mentioned.

The latest DJI Osmo Mobile 8P integrates three-axis stabilization, subject tracking, remote framing, an extension rod, a tripod, and phone power supply into a single device. It also provides shooting guidance and one-click post-production through DJI Mimo. With powerful software algorithms, gimbals have taken over some of the photographer's responsibilities, following subjects, adjusting composition, controlling camera position, and reminding users which shots to capture next for solo shooters.

Then there are wireless microphones, like the RØDE. Their significance lies in moving the microphone from the phone several meters away to the speaker's collar. While algorithms can reduce ambient noise, they can't eliminate the distance sound travels. For shop reviews (store exploration), street interviews, and dual Vlogs, wireless microphones remain the best solution.

Overall, lenses, screens, lights, gimbals, microphones, and apps may seem like different categories, but they're all becoming new tools that assist mobile imaging in becoming more powerful and professional. Although we've seen them in the camera field years ago, they don't hinder mobile photography from becoming more convenient while offering a better experience.

Accessories Matter Because Algorithms Can't Compensate for Physical Limitations

Reports show that as of December 2025, China's online audio-visual user base has reached 1.099 billion, with an average daily usage time of 201 minutes per person. The market size of the online audio-visual industry in 2025 is approaching 1.29 trillion yuan. Among major online applications with a usage rate exceeding 80%, short videos are the only segment to achieve growth in both user scale and usage rate.

Users previously accepted 'just capturing the shot,' but now the same phone might need to handle on-camera appearances, interviews, product displays, on-site recording, editing, and same-day publishing. As the phone itself approaches professional image quality, gaps in other areas become more noticeable. For example, the image might be clear enough, but subject tracking lags, or the video has a high dynamic range, but the sound is unclear. If material (footage) is shot in Log format, storage space and battery life might be insufficient. The bottleneck in mobile imaging is shifting from image quality limits to process limitations.

Distance is the first threshold that algorithms struggle to overcome. Digital zoom can't infinitely recover distant details, and noise reduction can't turn a voice from several meters away into a close-up whisper. Extender lenses and wireless microphones may seem unrelated, but they serve a similar purpose: both shorten the physical distance between the phone and the subject, making light or sound usable before entering the algorithm.

Light and motion won't disappear just because AI exists. Night scene synthesis excels at relatively stable scenes, but moving faces, constantly changing stage lights, and steaming dishes are more prone to motion blur and color shifts. Electronic image stabilization can offset some shaking through cropping, but it won't plan camera movements, continuously track subjects, or adjust composition from a distance for the user. Fill lights, gimbals, and selfie screens fill the gaps that occur before pixel calculations.

Then there's high-specification video, especially Log and RAW footage. The iPhone 15 Pro can already record ProRes at up to 4K 60fps directly to external storage with Log encoding. Manufacturers like Lexar and SanDisk are also designing SSDs around direct phone connections and magnetic external recording. Higher bitrates offer more post-production flexibility but also result in larger files, higher power consumption, and more noticeable heating.

The systematization of add-ons stems from mobile phones taking on too many roles. They need to serve as cameras, recorders, monitors, hard drives, editing stations, and publishing terminals simultaneously. As lenses push the upper limit of image quality higher and higher, any shortcoming (weak link) that doesn't keep up can ruin an entire video. At Leitech (ID: leitech), we believe the next competition in mobile imaging won't just be about who offers more accessories but also whether these components can seamlessly integrate.

More Imaging Accessories, But What About the Ecosystem?

vivo's extender lenses, OPPO and Honor's secondary screens, and various brands' dedicated photography grips are all reinventing a lightweight mount ecosystem. When users buy dedicated phone cases, lenses, filters, and grips, they're also leaving some future choices to the same brand. This logic is somewhat similar to the camera mount business, except that phone designs change faster. A dedicated accessory might only serve one generation of products, with a much shorter lifespan than a camera lens.

Cross-generational reuse will thus become the biggest question mark in this business. Whether new phones can remain compatible with previous-generation accessories, whether interfaces are willing to open up to third parties, and whether the same device can retain core functions across brands and apps will all affect users' willingness to continue investing. If every phone upgrade requires discarding lens cases, grips, and secondary screens along with the old device, the so-called ecosystem resembles an expensive consumable, making it hard to build long-term trust.

However, during the vivo XFold6 launch event's group interview, vivo officials revealed to Leitech that they do intend to establish vivo's extender lenses as a unified standard lens mount ecosystem. More future models may join this ecosystem, allowing extender lenses to remain usable even after the phone is obsolete.

Back to reality, more add-ons don't necessarily equal more professionalism. After attaching large lenses, cages, SSDs, power banks, coolers, and wireless microphones, the phone loses its most crucial feature: portability. Gimbals require setup and stowage, which might cause users to miss moments; cheap lenses might degrade image quality; wireless microphones and professional apps might lack some features on different Android models. As built-in stabilization, AI tracking, native audio recording, and computational photography continue to improve, a batch of low-value add-ons will still be eliminated.

Therefore, at Leitech, we believe mobile phone imaging add-ons should follow a different approach than cameras. For example, weight should be reasonably controlled to avoid sacrificing portability; installation should be easy and compatible with more products; stabilization, audio recording, storage, and editing shouldn't compete for interfaces or power; hardware and software should jointly complete the process from recording to final editing, and so on.

Ultimately, the mobile phone imaging ecosystem is compressing the complex workflows that once belonged to photographers, sound engineers, lighting technicians, and editors into a portable solution that ordinary people can carry and use spontaneously. For peripheral manufacturers, whoever can make these actions shorter, more stable, and more natural will win the next round of competition and become the center of mobile phone imaging.

Epilogue

It's not hard to see that whether it's moving extreme focal lengths outside the device with extender lenses, moving the viewfinder outside with selfie screens, or moving some of the photographer's and sound engineer's work outside with gimbals and wireless microphones, their ultimate goal is to elevate functions that mobile phones can only achieve at 60% to 80% or even 90% through add-ons.

However, this inevitably raises another voice in the market. Some consumers might worry that if manufacturers focus too much on add-ons and neglect the development of the phone's inherent capabilities, and since add-ons require additional purchases, is this a form of disguised price hike and putting the cart before the horse? For now, this concern might not be a real issue. After all, taking telephoto lenses as an example, the hardware limitations of phones are still very apparent, and extender lenses are indeed a superior solution.
