Kenko AB600-R AI Flash
The Kenko AI Flash AB600‑R is built to help photographers grow in confidence and take more control over their lighting. Portrait photography often relies on three key lighting approaches — bouncing light, using the flash off‑camera, and working with multiple flashes. These techniques can be challenging because they normally depend on experience and a good feel for how light behaves.
To make this easier, the AB600‑R includes an Auto Bounce feature that handles the most demanding part of the process for you. Instead of guessing angles or worrying about harsh shadows, the flash automatically adjusts to create soft, natural‑looking light. This allows photographers to focus more on creativity and expression rather than technical setup.
The AB600‑R is ideal for advanced beginners who want to start using flash but aren’t yet confident with lighting, as well as professionals who want to streamline their workflow and work more efficiently.
What “bounce” means
Bounce lighting is a popular flash technique in portrait photography. Instead of pointing the flash directly at your subject, the light is aimed at a nearby surface — usually a wall or ceiling — so it reflects back softly. This creates a more natural balance between highlights and shadows. Although it produces beautiful results, bounce lighting can be tricky because it requires a good understanding of angles, distance, and the environment. For many photographers, this is the part that feels most uncertain.

Without flash
Soft, even illumination from ambient light. The face looks natural and dimensional, with gentle shadows that add depth. No harsh reflections or strong wall shadows.

On-camera direct flash
Direct light from the camera creates bright highlights and sharp shadows. The face appears flatter and more reflective, with a distinct shadow cast on the wall behind the subject.

Bounce flash (ceiling)
Light is reflected from the ceiling, producing smooth, diffused illumination. The face retains shape and volume, and the wall shadow is soft and subtle, giving a professional, balanced look.
Main features
3D Auto Bounce
The AB600‑R’s 3D Auto Bounce calculates the best angle to bounce light off a wall or ceiling, giving you soft, natural lighting without trial and error. It’s ideal for fast‑moving shoots like weddings or tight portrait sessions where you can’t afford missed shots.
Auto Lock
After the flash sets a bounce angle, you can fine‑tune it and lock it in. The flash keeps that angle even when you rotate the camera, letting you stay focused on directing your subject rather than adjusting your gear.
Guide Number 60
With a maximum guide number of 60 (200mm, ISO 100), the flash has enough power for a wide range of lighting situations.
Remote Angle Control
The built‑in radio system lets a master flash adjust the bounce angle of a slave flash remotely, giving you more control in multi‑light setups.
Optical & 2.4GHz Radio Wireless
Supports both optical and 2.4GHz radio triggering for off‑camera and multi‑flash shooting. A sync port is also included.
Auto/Manual Zoom
The zoom head covers an 18–200mm range, with 18mm available when using the wide panel.
External Power
The optional BP‑1 battery pack provides stable power for long sessions.
AI Meaning
“AI” refers to Advanced Intelligence, highlighting the flash’s automated lighting features.
