The Insta360 X4 Air fits neatly between the flagship X5 and the older-but-capable X4. At $399, it is the cheapest 8K 360 camera on the market, yet it introduces key upgrades—larger 1/1.8-inch sensors, user-replaceable lenses, and a featherlight 165g body.

Design, Build & Portability
Truly featherlight — but not dramatically smaller
The X4 Air weighs 165g, making it Insta360’s lightest 8K 360 camera ever . It is 40g lighter than the X4 and about 35g lighter than the X5. The difference is immediately noticeable when you slip it into a pocket or bag . However, the camera is only 0.4 inches (10.7mm) shorter than the X5, with nearly the same width and depth. In hand, the size reduction feels modest .
Replaceable lenses and durable coating
The dual lenses are user‑replaceable, a feature carried over from the X5. If a lens cracks, you can buy a replacement kit for $40 and swap them yourself, saving a costly repair . Additionally, the lenses feature an ultra‑hard optical coating that doubles drop resistance compared to the X4 .
Color options and controls
Available in Graphite Black (matte, rugged) and Arctic White (sleek, fashion‑forward) . Physical controls include power/mode buttons on the side, a shutter button below the 2.5‑inch touchscreen, and a standard ¼‑20 tripod mount .
Image Quality & Performance
Daylight shooting is exceptional
During the day, the X4 Air’s 1/1.8-inch sensors capture crisp 8K footage with vibrant colors and good dynamic range. The larger sensors (compared to the X4’s 1/2‑inch) plus AdaptiveTone exposure balancing and Active HDR produce results that closely rival the X5 in good light.
Low‑light limitations are clear
The X4 Air lacks the PureVideo mode found on the X5, and its smaller sensors (1/1.8‑inch vs. X5’s 1/1.28‑inch) mean more noise in dim conditions. Reviewers consistently note that “during the day, the image quality between the two is quite similar… at night, the X5’s much larger sensor comes into play”.
Video modes for every scenario
- 8K/30fps: Max detail, ideal for 360 reframing and large displays.
- 6K/50fps & 4K/50fps: Smoother motion and smaller file sizes for fast action.
- Active HDR up to 8K/30fps: Balances highlights and shadows in real time, producing lifelike contrast .
- Single‑Lens Mode (4K/60fps): Uses either front or back lens for traditional wide‑angle video without 360 stitching .
- InstaFrame Mode: Records a flat “Selfie” or “Fixed View” video while simultaneously capturing the full 360 sphere .
Stills: adequate but not a focus
The X4 Air captures 29MP 360 photos and supports RAW. However, the stills resolution is capped, and the camera is clearly optimized for video. For serious photographers, the X5 remains a better choice .
Battery Life & Charging
Reliable for short sessions, not all‑day shoots
The 2,010mAh battery delivers:
- 88 minutes of continuous 8K/30fps recording (lab‑tested) .
- ~100 minutes at 6K/24fps in endurance mode .
- ~86 minutes of real‑world mixed use (on‑camera screen, Wi‑Fi on, occasional start/stop) – close to the lab figures .
This is a noticeable step down from the X4 (~120 minutes) and X5 (~208 minutes in endurance mode at 5.7K), but acceptable given the smaller, lighter chassis . For longer shoots, the Starter Bundle’s spare battery is highly recommended.
Charging: Via USB‑C. There is no external charger in the box, but third‑party options are available.
Insta360 Software & Unique Features
The app is best‑in‑class
Insta360’s companion app remains the gold standard for 360 content editing. AI‑powered tools like Auto Edit, FlashCut, and AI Frame automatically identify highlights, add transitions, and sync footage to music . You can reframe 360 footage into standard video with simple touch gestures or use presets to export perfectly framed clips in seconds . The app is so intuitive that most users do 95% of their editing on mobile .
Hands‑free controls
The X4 Air supports gesture and voice control for truly hands‑free operation. Twist the selfie stick or raise your palm to start recording – perfect for self‑shots or when the camera is mounted out of reach .

Frequently Asked Questions (FAQs)
Is the Insta360 X4 Air good for beginners?
Yes. It is arguably the best entry‑level 8K 360 camera. The software is intuitive, the controls are simple, and the price is accessible. For absolute beginners on a tighter budget, the older GoPro Max 2 might be an alternative, but the X4 Air offers better resolution and future‑proofing .
How does battery life compare to the X5?
In 8K/30fps recording, the X4 Air lasts about 88 minutes, while the X5 can exceed 200 minutes in its endurance mode (5.7K/24fps). However, that comparison is not apples‑to‑apples because the X5’s numbers are measured at a lower resolution. Still, for long‑form shooting (sports events, all‑day hiking), the X5 offers noticeably more runtime .
Can I replace the lenses myself?
Yes. The X4 Air includes the same user‑replaceable lens mechanism as the X5. If a lens is scratched or cracked, you can purchase the official lens kit (approx. $40) and swap them following the included instructions .
Is the X4 Air waterproof without a case?
Yes. It is rated for 15m (49ft) underwater without any housing – suitable for snorkeling, swimming, and surface water sports. For deeper diving, the optional Invisible Dive Case extends depth to 60m (197ft) .
What is InstaFrame mode?
InstaFrame mode simultaneously records a flat “selfie” or “fixed‑view” video and a full 360 video. This gives you a ready‑to‑share flat clip without editing, while preserving the full 360 sphere for later creative reframing .
Do I need a fast microSD card?
Yes. For reliable 8K/30fps recording, a UHS‑I Speed Class 3 (V30) card is recommended. Lower‑speed cards may drop frames or stop recording.
