GN46 Wireless Radio Control External Flash



Main characteristics

Intelligent communication maximises image quality

Stable GN460 output for a wide range of lighting needs

Because the HVL-F46RM is designed by Sony, it can communicate with α camera bodies to deliver consistent GN46 light output that meets professional lighting needs. Focal lengths from 24mm (15mm with the wide panel) to 105mm are supported.

Flash control linked to camera face detection0

With a compatible camera, white balance is automatically adjusted so that the subject’s face is rendered with natural colour. The HVL-F46RM works with a compatible camera face detection to provide ideal lighting for the main subject, even in groups.

Auto white balance accuracy that only original equipment can achieve

Thanks to in-house design, this advanced flash unit transfers colour temperature data to the camera where that data is used to precisely adjust white balance so that colours are rendered naturally in any situation.

Light output optimised for focal length and image size

The flash illumination angle is automatically adjusted to match the focal length of the lens used over a 24-105mm range. Light distribution is also adjusted for optimum illumination with full-frame or APS-C format.

Fast recycle and dependable high-speed continuous flash

Advanced electronics and construction contribute to fast recycle times and allow continuous flash shooting for extended periods of time. A set of four batteries can provide power for more than 320 flashes with 2.0 second recycle time

Innovative overheating prevention for longer shooting sessions

The use of heat resistant materials plus an optimised flash algorithm provides higher resistance to overheating that allows continuous shooting for longer periods of time. The HVL-46RM uses the same algorithms as the flagship HVL-F60RM2, achieving approx. 1.7 x greater overheating resistance than the HVL-F45RM so you can shoot without being interrupted by heat issues.

Intelligent communication boosts speed

Stable high-speed continuous flash shooting

With a compatible camera the HVL-F46RM can continuously provide flash for up to 60 frames in high-speed bursts at up to 10 fps. Missed frames dues to flash sync failure are avoided, providing stable continuous shooting support.

Up to 1/80000 second shutter sync with a compatible camera0 for new expression

Used with a compatible camera body, the HVL-F46RM allows flash sync up to 1/80000 second. In HSS (High Speed Sync) mode, it can sync at shutter speeds from 1/400–1/8000 second. This makes it possible to de-emphasise the background while using flash to illuminate the main subject, illuminate moving subjects against a bright background, and more.

Per-frame P-TTL flash control adapts to changing light

When used with a compatible camera, high-speed control sequencing in the camera uses pre-flash to control each individual flash during continuous bursts, even when tracking fast-moving subjects in scenes where the light changes dramatically.

Minimal flash trigger time lag0

When using the HVL-F46RM in combination with a compatible camera, time lag between pressing the shutter button and flash output is significantly reduced so that fleeting moments can be captured with confidence.

Intelligent communication enhances operability

Flexible bounce angle adjustment

This feature makes it possible to quickly angle the flash head 180 degrees to the left or right, 150 degrees up, or 8 degrees down, for easy bounce angle adjustment to match any subject and shooting environment.
User Interface controlling a flash from a compatible camera

Comprehensive control from compatible cameras

Flash compensation, ratio, and other parameters can be controlled directly from a compatible camera. A camera custom key can be used to call up the flash display for easy adjustment while looking through the viewfinder.

Dot-matrix display and custom keys for efficient operation

The same display tab format as the camera makes operation easy and intuitive. The Quick Navi display provides status info plus direct access to important parameters, with assignable arrow key, control wheel, and custom key input.

Higher reliability and operability

Enhanced dust and moisture resistance

A dust and moisture resistant design contributes to high reliability in outdoor conditions. Shoe sealing achieves even greater dust and moisture resistance with certain α series bodies.

Versatile radio wireless communication

Stable wireless radio communication is ensured at distances up to 30 m/98.4 ft. Reliable, error-free communication is achieved even around reflectors and obstacles. Slow sync, rear-curtain sync, and multi flash are supported.
