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.

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.
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.
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.
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.
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.
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. 1.7x greater overheating resistance than the HVL-F45RM so you can shoot without being interrupted by heat issues.
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.
Used with a compatible camera 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.
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.
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.
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.
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.
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.
A metal shoe foot with rugged side frame significantly increases the strength and durability of the Multi Interface Shoe and its electrical contacts.
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.
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.
Control up to 15 flash and/or receiver units in 5 groups. The HVL-F46RM can communicate with flash units that do not feature wireless radio communication via the optional FA-WRC1M commander and/or FA-WRR1 receiver.
