📸 Photo Performance
-
Image Quality: Sharp 24MP files with good dynamic range (better than most phones).
-
Low Light: Clean up to ISO 3200; noisy beyond that.
-
Autofocus: Still best-in-class for APS-C (beats Fujifilm X-T30 II in tracking).
-
Burst Shooting: 11 fps is great for sports/wildlife (but buffer fills fast).
Best for: Street photography, portraits, travel, and casual wildlife shots.
🎥 Video Performance
-
4K 30p (8-bit 4:2:0) – Decent for YouTube but lacks 10-bit for serious grading.
-
1080p 120fps (slow-mo) – Soft quality but usable for B-roll.
-
No Log Profiles in 8-bit? S-Log2/3 is there, but banding can happen in gradients.
-
Mic Input? Yes (3.5mm), but no headphone jack.
Best for: Vloggers, indie filmmakers (with stabilization help).
