The Sony Alpha 7 IV (ILCE-7M4 / α7 IV) is a 33.0-megapixel full-frame hybrid mirrorless camera engineered for wedding, commercial, and wildlife photographers as well as 10-bit 4:2:2 filmmakers, combining a back-illuminated Exmor R CMOS sensor and Dual BIONZ XR processors with 759-point Real-time Eye AF and dual CFexpress Type A / SD UHS-II card slots.
33.0MP full-frame BSI Exmor R sensor and 5.5-stop IBIS
Stepping up from 24MP predecessors, the α7 IV's 33.0MP 35mm full-frame (35.9 × 23.9 mm) back-illuminated Exmor R CMOS sensor and BIONZ XR engine deliver 15+ stops of dynamic range, native sensitivity from ISO 100 to 51,200 (expandable to ISO 50–204,800), and 14-bit uncompressed, lossless-compressed, or compressed RAW capture at up to 10fps. An upgraded 5-axis optical In-Body Image Stabilization mechanism provides up to 5.5 stops of shake compensation, paired with an optional anti-dust shutter-close-on-power-off setting to protect the sensor during lens swaps.
759-point Fast Hybrid AF with Human, Animal, and Bird Eye AF
Covering 94% of the image area with 759 phase-detection and 425 contrast-detection points, the Alpha 7 IV provides tenacious Real-time Tracking and Real-time Eye AF for humans, animals, and birds in both still photography and movie recording, focusing reliably in low light down to EV -4.0 (ISO 100 equivalent with an F2.0 lens).
10-bit 4:2:2 4K 60p cinema video, S-Cinetone, and pro connectivity
A dedicated Stills / Movie / S&Q sub-dial underneath the PASM dial switches instantly between photo and video custom settings. In full-frame mode, the α7 IV records 7K-oversampled 4K up to 30p; in Super 35 mode, it captures 4K up to 60p using full pixel readout without binning. Internal recording supports 10-bit 4:2:2 XAVC HS, XAVC S, and XAVC S-I (All-Intra up to 600Mbps) with S-Cinetone, S-Log3, Focus Breathing Compensation, and Focus Map. Professional hardware includes a 3.68M-dot 120fps OLED EVF, a side-opening 3.0-inch 1.03M-dot vari-angle touchscreen, a full-size HDMI Type-A port, Digital Audio MI Shoe, 3.5mm mic and headphone ports, 10Gbps USB-C 3.2 Gen 2 (with UVC/UAC 4K 15p / 1080p 60p live streaming), and dual card slots (Slot 1 CFexpress Type A / SD UHS-II; Slot 2 SD UHS-II).
