Sony A7iv Vs Canon R6 Which Mirrorless Camera Is Better For Video

Choosing between the Sony A7IV and the Canon EOS R6 isn’t just about megapixels or brand loyalty—it’s about matching capabilities to your creative needs, especially when video takes priority. Both cameras are flagship hybrid models designed for photographers and videographers alike, but their approaches to video differ in meaningful ways. For content creators, indie filmmakers, vloggers, and hybrid shooters, understanding these differences can make the difference between smooth production and constant compromise.

The Sony A7IV, released in 2021, builds on the legacy of the A7 series with refined video features and improved color science. The Canon R6, launched a year earlier in 2020, brought DSLR-level reliability into the mirrorless era with strong autofocus and dual-pixel AF dominance. While both deliver excellent image quality, their video strengths cater to different workflows and shooting styles.

Video Specifications Compared

At the heart of any video decision lies resolution, frame rates, bit depth, and codec options. These determine not only how sharp your footage looks but also how much flexibility you have in post-production.

Feature	Sony A7IV	Canon R6
Max Video Resolution	4K 60fps (full-frame, oversampled from 7K)	4K 60fps (with 1.1x crop)
10-bit 4:2:2 Recording	Yes (internal via S-Log3 & HLG)	Yes (internal via C-Log3)
8K Video	No	No
Slow Motion	1080p up to 120fps	1080p up to 120fps
Codecs	XAVC S, XAVC HS (H.265), All-I	MP4, MOV (H.264/H.265)
Recording Limit	Up to 1 hour (heat managed)	Approx. 40 minutes (thermal throttling)
External Recording	ProRes RAW via HDMI (with compatible recorder)	12-bit RAW via HDMI (with external recorder)

The A7IV pulls ahead slightly with true full-frame 4K 60fps without cropping, thanks to its 33MP sensor being oversampled from approximately 7K. This results in sharper detail, less moiré, and better overall image fidelity. The R6, by contrast, applies a 1.1x crop in 4K 60fps mode, which subtly tightens the field of view—something noticeable when using wide-angle lenses or working in tight spaces.

Tip: If you frequently shoot handheld or in confined environments, the lack of crop on the A7IV’s 4K 60fps mode gives more compositional flexibility than the R6.

Dynamic Range and Color Science

Dynamic range—the ability to retain detail in shadows and highlights—is critical for professional video. Both cameras offer log profiles, but their implementation and real-world performance vary.

The Sony A7IV includes S-Log3 and S-Gamut3.Cine, providing up to 15+ stops of dynamic range under optimal conditions. When graded correctly, footage from the A7IV holds shadow detail exceptionally well and recovers blown highlights with minimal noise. Its newer BIONZ XR processor improves tone mapping, making skin tones more natural straight out of camera—even in HLG (Hybrid Log-Gamma) mode.

The Canon R6 uses C-Log3, which Canon claims offers around 12 stops of dynamic range. While usable, it often requires more careful exposure since highlight recovery is less forgiving than S-Log3. However, Canon’s color science remains beloved by many cinematographers—especially for skin tones. Reds and flesh tones render naturally warm without excessive green-magenta shifts common in some Sony files before grading.

“Canon’s C-Log3 feels like a safety net—you can push it, but you’re rewarded for getting exposure right in-camera.” — Jordan Lee, Director of Photography, Vancouver-based filmmaker

For documentary shooters or run-and-gun operators who may not have time for meticulous exposure, the A7IV’s latitude provides more breathing room. But if you're lighting carefully and value organic color rendition, the R6’s cinematic warmth can reduce time spent color correcting.

Autofocus Performance in Video

Fast, reliable autofocus is non-negotiable for solo creators, event videographers, and anyone shooting without a dedicated focus puller.

The Sony A7IV features Real-time Tracking and Eye AF that works across humans, animals, and birds. In video mode, Eye AF locks onto subjects with near-instantaneous precision and maintains focus even during rapid movement or subject swaps. It’s particularly effective for vlogging, interviews, and moving shots where recomposing is frequent.

The Canon R6 also excels here with Dual Pixel CMOS AF II and subject detection—including people, animals, and vehicles. Its tracking is smooth and consistent, though slightly less aggressive than Sony’s. Some users report that the R6 prioritizes stability over speed, resulting in fewer focus hunts but occasional hesitation when switching subjects.

• Sony A7IV: Best for fast-paced scenes, active subjects, and dynamic framing.
• Canon R6: Ideal for controlled interviews, cinematic sequences, and situations where subtle focus transitions matter.

Both support touch-to-focus on the rear screen, useful for quick repositioning during solo shoots. However, the A7IV allows customizable AF activation buttons and more granular control over tracking sensitivity—features appreciated by advanced users.

Real-World Use Case: Wedding Videography

Consider Maria, a freelance wedding videographer based in Austin, Texas. She previously used DSLRs but transitioned to mirrorless for lighter gear and better stabilization. She tested both the A7IV and R6 during a summer wedding season.

Shooting outdoors under harsh sunlight, she found the A7IV handled blown skies and shaded faces better due to superior dynamic range. During the ceremony, the camera’s Eye AF kept focus locked on the bride even as she turned toward the window—critical for capturing emotional moments without missing focus.

However, during the reception, she switched to the R6. The ambient golden-hour lighting paired beautifully with Canon’s color science. Her clients loved the “filmic” warmth of the footage, and minimal grading was needed. She noted, however, that focusing in low light required manual override at times, whereas the A7IV maintained lock more consistently.

Maria now uses the A7IV as her primary camera for ceremonies and outdoor events, reserving the R6 for second-unit or stylized portrait segments. “Each has its place,” she says. “The Sony gets the shot; the Canon makes it beautiful.”

Ergonomics, Build, and Workflow Integration

A camera’s feel in hand and menu layout can impact efficiency more than specs alone.

The Sony A7IV features a redesigned menu system with touchscreen navigation, customizable My Menu tabs, and a top status LCD—absent on the R6. Its grip is deeper, offering better balance with heavy lenses. The inclusion of a fully articulating touchscreen benefits vloggers and self-shooters, while the R6’s vari-angle screen flips out sideways, which can be obstructed by large lenses.

Battery life favors the R6: it uses the LP-E6NH, delivering around 500 shots per charge (approx. 90 minutes of continuous video). The A7IV uses the newer Z battery (NP-FZ100), rated slightly lower but still sufficient for most shoots. Both support USB-C charging, allowing use with power banks in the field.

In terms of connectivity, both offer Wi-Fi, Bluetooth, and clean HDMI output. The A7IV adds Ethernet via optional adapter (important for live streaming), while the R6 lacks this option entirely—a drawback for corporate or broadcast applications.

“The small things add up: the A7IV’s silent shutter, faster menu access, and better screen design save me minutes every shoot.” — Lena Torres, Commercial Videographer

Step-by-Step: Choosing Based on Your Needs

Follow this decision path to determine which camera aligns best with your workflow:

1. Assess your primary shooting environment: Do you work indoors, outdoors, or in mixed lighting? High-contrast scenes favor the A7IV’s dynamic range.
2. Determine your editing capacity: Can you grade log footage extensively? If not, the R6’s natural colors may suit you better.
3. Test autofocus demands: Are you filming fast-moving subjects? Choose A7IV. Static interviews or narrative work? R6 performs admirably.
4. Consider lens ecosystem: Sony’s third-party support (via Sigma, Tamron, Samyang) is unmatched. Canon RF glass is high quality but limited and expensive.
5. Evaluate budget beyond body cost: Factor in memory cards (A7IV benefits from CFexpress Type A for high-bitrate recording), batteries, and accessories.

Tip: Rent both cameras for a weekend project before committing. Real-world handling often reveals preferences no spec sheet can predict.
