I provided ChatGPT with the full Canon R6 III specifications and transcripts from a dozen respected YouTube reviewers, then asked it to create a detailed comparison between the Canon R6 III and the Sony A7 IV.

📸 SENSOR & IMAGE QUALITY
Canon R6 Mark III: 32.5 MP BSI CMOS (non-stacked)
Sony A7 IV: 33 MP BSI CMOS (non-stacked)
➡ Tie – Both sensors are very close in resolution and dynamic range.

⚡ SPEED & BUFFER
Canon: 12 fps (mechanical) / 40 fps (electronic) + RAW pre-capture (≈ 0.5 s before press)
Sony: 10 fps max (mechanical or electronic) (no pre-capture)
➡ Canon wins by far – 4× faster, pre-capture records before you even react, and the new CFexpress Type B slot clears buffers up to 5× faster. Wildlife testers confirmed ≈ 200 RAWs at 40 fps before slowdown.

🎯 AUTOFOCUS & SUBJECT DETECTION
Canon: Dual Pixel AF II + Deep Learning AI, registers faces (10 people / 6 groups), tracks animals, birds, vehicles with face priority. Works down to –6.5 EV.
Sony: Real-Time Tracking AF with human & animal eye AF (+ bird mode since firmware v2.0). Works down to –4 EV.
➡ Canon wins – The new “face registration” and steadier small-subject tracking outperform Sony’s AF in complex scenes.

🪄 STABILIZATION
Canon: up to 8.5 stops IBIS + lens IS sync
Sony: 5.5 stops IBIS
➡ Canon clearly ahead – Stable handheld video even at 600–1200 mm and razor-sharp 1/5 s stills.

🎥 VIDEO CAPABILITIES

➡ Canon wins decisively – 7K RAW oversample, C-Log 2/3, waveforms, false color and full HDMI bring it into pro-video territory. Sony is strong for hybrid use but less advanced for video work.

🧠 REAL-WORLD USABILITY
Canon’s field tests highlight its wildlife excellence: fast, accurate AF; reliable tracking on tiny birds; impressive high-ISO sharpness (up to ISO 12 800 clean). Pre-capture proved “game-changing.” Sony feels slower for bursts and less intuitive in AF-mode switching.

🌙 LOW-LIGHT & DYNAMIC RANGE
Both perform well up to ISO 12 800. Canon’s BSI design offers strong detail retention; Sony retains slightly more shadow latitude at base ISO.
➡ Tie / slight Canon edge at high ISO; Sony edge in shadow dynamic range.

📁 MEDIA & CONNECTIVITY
Canon: CF Express Type B + UHS-II SD, full HDMI, mic + headphone, USB-C PD power.
Sony: 2× UHS-II SD (or limited CF Express Type A slot).
➡ Canon wins – faster cards, pro connectors, cleaner tethering.

🔋 BATTERY & THERMALS
Canon: LP-E6P battery, good thermal control (but 7K RAW heats up).
Sony: NP-FZ100 battery = slightly longer photo runtime.
➡ Tie – Canon better for video power, Sony for stills longevity.

💡 ERGONOMICS & BUILD
Both are weather-sealed magnesium bodies. Canon’s grip and menus are praised for comfort; Sony for customization.
➡ Canon favored by most reviewers for handling and workflow.

💰 PRICE (Nov 2025)
Canon R6 III ≈ € 2 799 / $ 2 799
Sony A7 IV ≈ € 1 949 / $ 1 998
➡ Sony wins on price (≈ $ 800 less).

🔥 FINAL TAKE
If you’re a hybrid shooter or wildlife / sports photographer, → Canon R6 Mark III is the clear winner: faster bursts, pre-capture, superior AF, 8.5-stop IBIS, and pro-grade video tools.
If you’re budget-conscious or primarily a portrait / studio shooter, → Sony A7 IV remains an excellent alternative with mature color workflow, longer battery life, and slightly better shadow recovery.

Sony just raised the bar again for AF performance and accuracy with it’s new firmware updates for the Sony A1II and Sony A9III camera bodies. This new 4.0 firmware update packs a new level of AI to assist sports and action photographers so they almost never miss a shot.

Gone are the days when Sony gave us lame firmware updates. Now we really got new remarkable features!

Chris calls the Sigma 20–200 mm a “perfect travel companion” — compact, sharp, and highly versatile, ideal for those who want one lens for everything. It’s not bright enough for serious night or portrait work, but for daytime city, landscape, and street photography, it performs impressively well.

The new SongRaw AF 50mm f/1.2 ‘Moonlit’ lens is now available for preorder on Amazon (Click here). And here are the first reviews:

His thoughts in short:

The Laowa 200mm f/2 offers outstanding value for money at $2000. It’s lighter, sharp stopped down, and produces beautiful bokeh, though autofocus is only average and it lacks image stabilization. The Sigma 200mm f/2 is a more professional lens overall. It costs $3300, but justifies it with:

• Sharper image quality at f/2
• Faster, more reliable autofocus
• Optical image stabilization
• Superior build quality

If you’re on a budget and want great results, go Laowa. If you’re a pro needing top-tier performance, go Sigma.
