For nearly a decade, I've tested phones, and every year a brand claims their device can replace a DSLR or mirrorless camera. I usually respond with a raised eyebrow. Yet, I've seen a few phones that genuinely mimic "real" camera results—through image processing, tactile feedback, or hardware innovations. The vivo X300 Pro leans on computational photography, the OPPO Find X9 Pro uses a motorized lens for physical feedback, and the Xiaomi 17 Ultra introduces a variable aperture. This last feature reminds me why Samsung and Google should step up their camera game. Below, I answer common questions about these developments.
1. Why do so many phone camera claims about replacing DSLRs get met with skepticism?
Phone manufacturers often promise DSLR-level quality, but physics limits small sensors and lenses. Even top phones like the latest Samsung or Google Pixels struggle with low light, depth of field, and optical zoom compared to dedicated cameras. The hype usually oversells computational photography tricks that only simulate bokeh or zoom. After reviewing countless devices, I've learned to expect good photos—but not a true DSLR replacement. The Xiaomi 17 Ultra's variable aperture, however, addresses one of the biggest gaps: control over light and depth in a compact form. See Question 5 for details on that feature.
2. Which phones have come closest to replicating a DSLR-like experience?
Three models stand out recently. The vivo X300 Pro focuses on post-processing to create a shallow depth-of-field appearance similar to portrait mode on a full-frame camera. The OPPO Find X9 Pro adds a physical extendable lens that gives tactile feedback when zooming, mimicking the feel of a real camera barrel. And the Xiaomi 17 Ultra uses a variable aperture on one rear lens, allowing the user to adjust the f-stop for more control over exposure and bokeh. Each approaches the gap differently—software, hardware, or both.
3. How does the vivo X300 Pro achieve a DSLR-like effect through software?
The vivo X300 Pro relies heavily on algorithmic image processing to simulate a shallow depth of field. By using multi-frame compositing and advanced subject detection, it blurs the background in a way that resembles a fast prime lens. The effect can look impressive in well-lit conditions, but it often struggles with fine hair or edges. It's a purely superficial trick—the optical hardware stays fixed. So while the output looks like a DSLR image, the process is entirely digital. Compare this to the Xiaomi 17 Ultra's hardware approach in Question 5.
4. What makes the OPPO Find X9 Pro's tactile feedback special?
OPPO added a motorized extendable lens to the Find X9 Pro's camera module. When you zoom, the lens physically moves in and out, providing subtle vibration and sound similar to a traditional camera. This isn't just a gimmick; it helps the user feel the zoom range and adds a layer of control absent from most phones. The tactile feedback reinforces that you're using a serious imaging device, not just a slim slab. Combined with good optics, it creates a more engaging photography experience. Yet, it still lacks the variable aperture control found in the Xiaomi 17 Ultra.
5. Why is the Xiaomi 17 Ultra's variable aperture a significant step forward?
The Xiaomi 17 Ultra incorporates a variable aperture on its main rear camera—much like a traditional camera lens. Users can adjust the f-stop from, say, f/1.4 to f/4.0, altering depth of field and light intake. This gives photographers creative control: wider apertures for soft backgrounds, narrower for sharper landscapes. It also helps with exposure in bright conditions. This hardware feature bridges a major gap between phones and DSLRs. Other brands like Samsung and Google rely on fixed apertures and software fixes, which can't replicate the same optical quality. That's why I believe they need to catch up.
6. Why do Samsung and Google need to catch up in camera hardware innovation?
Samsung and Google are leaders in computational photography—their image processing is top-tier. But they lack innovative hardware like variable apertures or motorized lenses. Their flagships (Galaxy S24 Ultra, Pixel 8 Pro) use fixed apertures and rely on multi-frame HDR or AI to mimic depth. While excellent, they can't match the physical control offered by Xiaomi's variable aperture. As competition heats up, consumers expect more than just software tricks. To truly rival DSLRs, Samsung and Google must explore adaptable optics. Otherwise, phones like the Xiaomi 17 Ultra will set a new standard that others can't reach.
7. What can consumers expect from phone cameras in the next few years?
Expect more brands to adopt variable apertures and moving lens elements. Xiaomi's lead may push Samsung, Google, and others to merge hardware innovation with their AI skills. We'll likely see better optical zoom, physical controls, and improved low-light performance. However, physics still limits sensor size, so DSLRs won't vanish. The key is a blend of hardware and software—like the Xiaomi 17 Ultra's variable aperture plus Google's HDR+. If brands collaborate on these fronts, phone photography will inch even closer to professional cameras. For now, the gap narrows, but it's not gone yet.
