Compact GN461 flash supports the latest camera technology
This compact high-output GN461 flash unit delivers levels of sophistication and camera communication that only Sony can offer, offering reliable flash at high continuous shooting speeds and sync at shutter speeds up to 1/400 sec2. Outstanding durability, intuitive operation via the camera2, flexible bounce angle adjustment, and wireless radio communication add refined control and versatility.
Intelligent communication with the α body
The α Lighting System has evolved in parallel with α camera bodies to give creators optimum illumination in a wide range of applications. A level of integration that is only possible with original Sony products achieves detailed communication with compatible camera bodies for reliable and precise light control.

Stable GN461 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 105mm2 are supported.
Per-frame P-TTL flash control adapts to changing light
When used with a compatible camera3, high-speed control sequencing in the camera uses pre-flash to control each individual flash4 during continuous bursts, even when tracking fast-moving subjects in scenes where the light changes dramatically.
Up to 1/400 sec. shutter sync with a compatible camera3 for new expression
Used with a compatible camera3 body the HVL-F46RM allows flash sync up to 1/400 sec. This makes it possible to deemphasise the background while using flash to illuminate the main subject, illuminate moving subjects against a bright background, and more.
Stable high-speed continuous flash shooting
With a compatible camera3 the HVL-F46RM can continuously provide flash for up to 60 frames5 in high-speed bursts at up to 10 fps. Missed frames dues to flash sync failure are avoided, providing stable continuous shooting support.
Flash control linked to camera face detection2
With a compatible camera3, white balance is automatically adjusted so that the subject’s face is rendered with natural colour. The HVL-F46RM works with a compatible camera3 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.
Minimal flash trigger time lag6
When using the HVL-F46RM in combination with a compatible camera3, time lag between pressing the shutter button and flash output is significantly reduced7 so that fleeting moments can be captured with confidence.
Selectable flash distribution types
Three selectable flash distribution types are provided: Standard (STD), GN priority (CENTER), and wide-angle priority (EVEN).
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.
High-speed, slow, and rear-curtain sync
High-speed sync works at all shutter speeds8, and can be used with the aperture wide open to produce beautiful background bokeh for portraits. Slow sync and rear-curtain sync are also supported.
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-F46RM uses the same algorithms as the flagship HVL-F60RM2, achieving approx. 1.76 x greater overheating resistance than the HVL-F45RM so you can shoot without being interrupted by heat issues.
Metal shoe foot with rugged side frame
A metal shoe foot with rugged side frame significantly increases the strength and durability of the Multi Interface Shoe and its electrical contacts.
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 time9.
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.
Comprehensive control from compatible cameras
Flash compensation, ratio, and other parameters can be controlled directly from a compatible camera2. A camera custom key can be used to call up the flash display for easy adjustment while looking through the viewfinder.

Enhanced dust and moisture resistance
A dust and moisture resistant design10 contributes to high reliability in outdoor conditions. Shoe sealing achieves even greater dust and moisture resistance with certain a series bodies.
Improved rear-panel Quick Navi display
Pressing the Fn button causes the selected flash mode and other parameters to appear on the display for easy setup in a variety of shooting situations. While the previous HVL-F46RM flash only displayed the Wireless OFF and Memory Recall OFF icons when the Fn button was pressed, these parameters are normally visible on the HVL-F46RM display.
Versatile radio wireless communication
Stable wireless radio communication is ensured at distances up to 30 m/98.4 ft6. Reliable, error-free communication is achieved even around reflectors and obstacles. Slow sync, rear-curtain sync, and multi flash are supported2.
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.
Multi/Micro USB for computer connection
The HVL-F46RM has a Multi/Micro USB terminal that allows connection to a computer for software upgrades.
