Canon Speedlite 420EX Shoe Mount Flash - Good Condition | High-Performance E-TTL Automatic Speedlight Featuring 90° Bounce, 270° Swivel, and Fully Automated Multi-Zone Autofocus Assist Beam

Introductory Paragraph The Canon Speedlite 420EX is a highly reliable, fully automatic electronic shoe-mount flash engineered by Canon in Japan. Designed to integrate seamlessly with the Type-A E-TTL automatic flash exposure algorithms of vintage film SLRs and modern digital DSLRs, it delivers exceptionally accurate exposures without requiring tedious manual calculations. Equipped with a motorized zoom flash head, full bounce articulation, and an advanced multi-zone autofocus assist array that locks onto subjects in pitch-black environments, this highly scannable Canon speedlight provides an effortless, satisfying lighting tool perfect for event photographers, portrait artists, and daily family documentarians.

Key Features

• Advanced E-TTL through-the-lens automatic flash metering, analyzing ambient and pre-flash lighting details to output perfectly balanced exposures.

• Powerful Guide Number rating scale (42m / 138ft at ISO 100), supplying robust illuminating output for bounce scenarios and bright daylight fill tasks.

• Comprehensive bounce and swivel articulation geometry, tilting upward up to 90° and rotating 180° left / 90° right for versatile soft-lighting control.

• Motorized automatic zoom head mechanics, adjusting from 24mm to 105mm focal configurations automatically to mirror the camera's attached lens profile.

• Multi-zone autofocus assist beam emitter network, projecting a bright pattern to assist the camera's AF sensor array in zero-light environments.

• Built-in wireless optical slave capability, receiving firing commands seamlessly off-camera from a master speedlight or compatible transmitter unit.

• Simplified clutter-free physical rear panel configuration, prioritizing streamlined automatic shooting metrics with clear LED confirmation readouts.

Condition Report Good condition. Body: Shows standard light signs of use, including typical minor surface scuffs on the black polycarbonate outer housing and faint bright wear lines near the hot shoe foot. The battery compartment door hinges tightly, and the lock release dial operates smoothly. Sensor/Optics: The front fresnel lens panel is completely clean, clear, and free from thermal discolouration, deep scratches, or cracks. Mechanics/Electronics: Fully operational. The flash powers on immediately, the zoom head tracks motorized focal shifts uniformly, the bounce/swivel joints click into position positively, and the strobe fires reliably on command with rapid recycling times.

Specialist Note "The Canon Speedlite 420EX is highly celebrated for its 'plug-and-play' simplicity. While modern flashes clutter up their rear panels with overly dense sub-menus, the 420EX offloads its brainpower to your camera body, giving you perfect automatic exposures automatically. Its motorized zoom adjusts seamlessly as you spin your lens ring, and the full swivel head lets you bounce light off walls or ceilings for professional, soft results. It's a completely transparent, satisfyingly dependable tool that works flawlessly across decades of Canon camera bodies."
