Sony Alpha 7 IV Full-Frame Mirrorless Interchangeable-Lens Camera, Body Only, Black ILCE7M4/B

Product Overview

The Sony Alpha 7 IV is a full-frame mirrorless interchangeable-lens camera introduced in 2021. The B09JZT6YK5 configuration corresponds to the body-only U.S. Alpha 7 IV, identified by Sony as model ILCE-7M4 and commercial product designation ILCE7M4/B. Sony classifies the camera as a hybrid model intended for both still photography and video production.

The camera uses a 35.9 × 23.9 mm back-illuminated Exmor R CMOS sensor with approximately 33.0 effective megapixels. Processing is handled by Sony’s BIONZ XR imaging engine. The Alpha 7 IV uses the Sony E-mount and accepts compatible full-frame FE lenses as well as supported APS-C E-mount lenses.

For still photography, the camera supports continuous shooting at up to approximately 10 frames per second under specified settings, 14-bit RAW capture, in-body image stabilization, and a hybrid autofocus system with 759 phase-detection points. Video capabilities include 4K recording up to 60p, 10-bit 4:2:2 recording, S-Cinetone, S-Log profiles, and USB streaming. The 4K 60p mode uses a Super 35mm crop rather than the full sensor width.

Product Identifier Summary

Model Number

A model number identifies a particular camera design within a manufacturer’s product family. ILCE-7M4 identifies the Alpha 7 IV body and distinguishes it from models such as the Alpha 7 III, Alpha 7R series, and later Alpha 7 generations.

MPN

A Manufacturer Part Number distinguishes a specific commercial configuration. ILCE7M4/B identifies the U.S. body-only Alpha 7 IV configuration listed by Sony.

UPC

A UPC is a 12-digit retail barcode used for inventory management and product matching. An exact UPC is omitted because an authoritative value tied conclusively to this specific configuration was not established.

EAN

An EAN is an international barcode identifier used in retail distribution. A verified EAN for this exact U.S. configuration was not established and is therefore omitted.

GTIN

A GTIN is a standardized trade identifier that can include UPC and EAN formats. No exact GTIN is included because a manufacturer-verified value for this configuration was not established.

ASIN

The ASIN identifies the supplied catalog record used as the starting point for researching this product. It is separate from Sony’s manufacturer-issued model and part numbers.

ISBN

ISBN identifiers are used for books and qualifying publications and do not apply to digital cameras.

Maintenance & Care

The Alpha 7 IV contains a removable lens system, exposed electrical contacts, an image sensor assembly, mechanical controls, and weather-resistant body seals. Routine care should limit dust, moisture, impact, and contamination.

• Turn the camera off before changing lenses, batteries, or memory cards.
• Keep the body cap installed when no lens is attached.
• Change lenses in a clean environment when possible to reduce sensor contamination.
• Use a blower designed for photographic equipment to remove loose dust.
• Do not touch the image sensor with fingers or ordinary cleaning cloths.
• Clean lenses according to the lens manufacturer’s instructions.
• Use a soft, dry cloth for normal exterior cleaning.
• Keep electrical contacts free from moisture and debris.
• Allow condensation to evaporate before operating the camera after a rapid temperature change.
• Store batteries separately during long periods of non-use when appropriate.
• Install current Sony firmware when required for compatibility, stability, or supported feature updates.

Safety Information

• Use the specified NP-FZ100 rechargeable battery or compatible Sony-approved replacement.
• Do not use swollen, leaking, punctured, or otherwise damaged lithium-ion batteries.
• Keep batteries away from fire and excessive heat.
• Do not short-circuit exposed battery terminals.
• Use compatible USB Power Delivery equipment when powering or charging through USB-C.
• Do not expose the camera to conditions beyond its documented operating temperature range.
• The body includes resistance measures against dust and moisture but is not guaranteed to be completely dustproof or waterproof.
• Secure heavy lenses appropriately because large lenses can place substantial mechanical load on the mount and camera body.

Technical Specifications

The following specifications are based primarily on Sony’s official Alpha 7 IV support documentation and product specifications.

Product History

Sony introduced the Alpha 7 IV in 2021 as the successor to the Alpha 7 III. The fourth-generation model increased effective resolution from the earlier model’s approximately 24-megapixel class to 33 megapixels and introduced the newer BIONZ XR processing platform, revised autofocus functions, improved video recording options, a fully articulating display, and an updated menu system.

The Alpha 7 IV remained part of Sony’s full-frame E-mount lineup after Sony introduced the Alpha 7 V in 2025. The Alpha 7 V is the subsequent numbered model in the standard Alpha 7 family rather than a firmware revision of the Alpha 7 IV.

Buying Considerations

Body-Only Configuration

This configuration does not include an interchangeable lens. A compatible E-mount lens is required for normal photography and video recording.

Full-Frame Lens Coverage

FE lenses are intended to cover the camera’s full-frame sensor. APS-C lenses can be used in supported crop modes but do not provide the same full-frame image area.

4K 60p Crop

Users requiring 4K 60p should account for the Super 35mm crop. This changes the effective field of view compared with full-frame recording at lower frame rates.

Memory-Card Requirements

Some high-bit-rate recording modes require faster SDXC or CFexpress Type A media. Card specifications should be matched to the intended video format rather than relying only on storage capacity.

Continuous Shooting

The headline 10 fps rate depends on image format and camera settings. Lossless compressed or uncompressed RAW recording can reduce maximum burst speed.

Camera Size and Lens Weight

The body itself weighs approximately 658 grams in operating configuration. Total system weight can increase substantially when professional zoom or telephoto lenses are attached.

Successor Model

The Alpha 7 V is a newer generation in the same product line. Users comparing generations should distinguish newer autofocus, processing, burst, and video capabilities from the Alpha 7 IV specifications documented here.

Customer Feedback Summary

This section summarizes recurring themes reported in professional evaluations and publicly available user discussions. These observations are generalized experiences rather than verified product specifications. Independent reviews commonly describe the Alpha 7 IV as a capable hybrid camera with strong autofocus, image quality, handling, and video features.

Commonly Praised Aspects

• Autofocus tracking is frequently praised for maintaining focus on people and moving subjects.
• The 33-megapixel sensor is commonly viewed as providing a useful balance between image detail and manageable file sizes.
• The revised menu system is often considered easier to navigate than earlier Alpha 7 generations.
• The fully articulating screen is frequently appreciated for video, self-recording, and unusual shooting angles.
• Still-image quality is commonly praised across a broad range of lighting conditions.
• 10-bit video recording and S-Cinetone are often cited as useful additions for hybrid creators.
• Dual memory-card slots are commonly valued for backup and overflow recording.
• The NP-FZ100 battery is generally considered more practical for extended use than batteries used in earlier generations of Sony mirrorless cameras.

Commonly Reported Limitations

• The Super 35mm crop in 4K 60p changes wide-angle framing and is frequently mentioned by video users.
• The maximum 10 fps burst rate can decrease when certain higher-quality RAW formats are selected.
• Rolling-shutter effects may become visible during rapid camera movement or fast-moving subjects in some electronic and video recording situations.
• The electronic viewfinder and rear LCD are functional but have lower resolution than displays used in some higher-tier camera bodies.
• CFexpress Type A cards can add cost for workflows requiring the fastest supported recording media.
• The body is larger and heavier than some compact full-frame mirrorless cameras.
• Long video sessions can be affected by camera-temperature settings, ambient conditions, and recording format.

Individual experience varies with lenses, firmware, memory cards, temperature, shooting settings, and photographic technique. Customer and reviewer observations should therefore not be treated as guaranteed performance measurements.
