When Apple released the iPhone 8 and iPhone 8 Plus in 2017, they represented a bridge between classic iPhone design and modern camera capabilities. While both phones shared many features—A11 Bionic chip, glass backs, wireless charging—one critical difference stood out: the camera system. The iPhone 8 has a single 12MP rear lens, while the 8 Plus adds a second telephoto lens for optical zoom and Portrait Mode. But does that extra lens deliver enough value to justify choosing the 8 Plus over the 8? For photographers, casual shooters, or anyone still using these devices today, this question remains relevant.
This isn’t just about technical specs—it’s about real-world usability, photo quality in varied conditions, and whether the dual-lens experience translates into meaningful improvements. Let’s break down the differences with practical insight.
Camera Hardware: What Sets Them Apart
The foundation of any camera comparison lies in the hardware. Both iPhones feature 12MP sensors with optical image stabilization (OIS), wide apertures (f/1.8 on the main lens), and support for 4K video recording. However, their configurations diverge significantly:
- iPhone 8: Single 12MP wide-angle lens (28mm equivalent, f/1.8)
- iPhone 8 Plus: Dual 12MP setup — wide-angle (28mm, f/1.8) + telephoto (56mm, f/2.8)
The addition of the telephoto lens enables two key features absent on the iPhone 8: 2x optical zoom and Portrait Mode. These aren’t minor conveniences—they represent a shift in how you can compose and capture images.
Portrait Mode: More Than Just a Gimmick
Portrait Mode was Apple’s answer to DSLR-style depth-of-field effects on smartphones. It uses data from both lenses to create a depth map, blurring the background while keeping the subject sharp. On the iPhone 8 Plus, this feature works reliably in good lighting and produces natural-looking bokeh.
The iPhone 8 lacks this capability entirely. You can simulate background blur using third-party apps, but the results are inconsistent and lack the real-time preview and post-capture adjustments (like changing focus or light effect) available on the 8 Plus.
“Portrait Mode changed how people approach mobile photography. It’s not just about aesthetics—it encourages intentionality in framing.” — David Lin, Mobile Photography Instructor at SF Media Arts
In practice, Portrait Mode shines when shooting portraits, food, or small objects. The shallow depth effect draws attention to the subject, making photos stand out on social media or in personal albums. For users who share photos regularly, this is a tangible advantage.
Zoom Performance: Optical vs Digital
One of the most underappreciated benefits of the dual-camera system is lossless zoom. The iPhone 8 Plus allows 2x optical zoom without sacrificing image quality. Beyond that, Apple combines optical input with digital cropping intelligently up to 10x total zoom (hybrid zoom).
In contrast, the iPhone 8 relies solely on digital zoom. At 2x magnification, details begin to soften. By 4x, images often appear pixelated, especially in lower light.
| Zoom Type | iPhone 8 | iPhone 8 Plus |
|---|---|---|
| Optical Zoom | No | Yes (2x) |
| Digital Zoom Quality | Moderate degradation beyond 2x | Sharper due to hybrid processing |
| Best Use Case | Close-range shots only | Concerts, wildlife, distant subjects |
If your photography includes capturing moments from a distance—say, a child on stage or a landscape detail—the 8 Plus offers a clear edge.
Low-Light and Dynamic Range Comparison
Both models perform similarly in bright daylight, producing vibrant colors and excellent dynamic range. However, in low-light scenarios, subtle differences emerge.
The iPhone 8 Plus doesn’t have Night Mode (introduced later), but its dual cameras assist in focusing and exposure calculation. In dim environments, the telephoto lens helps stabilize framing during zoomed shots, reducing motion blur. Additionally, the wider field of view from the main lens captures more ambient light, which benefits HDR processing.
While neither phone matches current-generation iPhones in night photography, user reports suggest the 8 Plus handles high-contrast scenes—such as sunsets or indoor lighting with windows—slightly better due to improved tone mapping.
Real-World Example: A Day at the Zoo
Consider Sarah, a parent visiting the zoo with her toddler. She owns an iPhone 8 and wants to photograph animals across enclosures. Without optical zoom, she relies on digital zoom, resulting in blurry tiger close-ups and cropped peacocks that lose feather detail.
Her friend Mark, using an iPhone 8 Plus, switches to 2x zoom effortlessly. His photos retain crispness, and he even captures a playful monkey mid-leap using Portrait Mode to isolate the subject against foliage.
Later, both take group photos. Mark activates Portrait Mode to blur the noisy background, making his family stand out. Sarah’s photo, though well-composed, looks flat by comparison.
In this scenario, the dual-lens system doesn’t just offer convenience—it expands creative possibilities.
Video Capabilities: Subtle Yet Meaningful Differences
Both phones record 4K video at 30fps and 1080p at 60fps, with stereo audio and OIS. However, the iPhone 8 Plus supports “zoom during recording” with less digital artifacting thanks to optical input. You can smoothly transition from wide to 2x zoom without the choppiness typical of digital-only systems.
Additionally, filmmakers appreciate the ability to shoot in Portrait Lighting modes (though limited to stills), which train the eye for composition and lighting control—even if used only for storyboarding ideas.
Frequently Asked Questions
Can I get Portrait Mode on iPhone 8 with software updates?
No. Portrait Mode requires depth data from a second lens. Apple has never enabled this feature via software on single-lens devices due to hardware limitations.
Is the battery life affected by using the dual cameras?
Minimal impact. Processing dual inputs uses slightly more power, but real-world usage shows no significant difference in daily battery drain between the two models.
Does the iPhone 8 Plus take better regular photos than the iPhone 8?
In standard wide-angle shots, image quality is nearly identical. The primary sensor and software processing are the same. The advantage only becomes apparent when using zoom or Portrait Mode.
Action Checklist: Choosing Based on Your Needs
Use this checklist to decide whether the dual-lens system matters for your use case:
- Do you often take portraits of people or pets? → iPhone 8 Plus preferred
- Do you need to zoom in on distant subjects without quality loss? → iPhone 8 Plus required
- Is phone size a concern? (8 Plus is larger) → iPhone 8 may be better fit
- Are you primarily sharing casual snapshots online? → iPhone 8 sufficient
- Do you value future-proofing for photo editing flexibility? → 8 Plus offers more options
Final Verdict: Is the Dual Lens Worth It?
The answer depends on what kind of photographer you are—or want to become. If your goal is simplicity and solid everyday performance, the iPhone 8 delivers excellent results. Its single camera handles most situations gracefully, and you benefit from a more compact form factor.
But if you care about creative control—shooting portraits with professional flair, capturing distant subjects clearly, or experimenting with depth effects—the iPhone 8 Plus isn’t just marginally better. It opens doors the iPhone 8 simply cannot.
Even years after release, the dual-lens system proves its value. It’s not about having “more” cameras; it’s about having the right tool for different visual stories. For anyone serious about mobile photography, even casually, the investment pays off in richer, more expressive images.
