Additional information
relating to Canon Speedlite
430EZ
A specially designed, dedicated Speedlite for the original EOS-1 back in 1989. Canon's
sophisticated A-TTL flash shooting mode takes all the worry out of flash photography.
Set your EOS-1 on program AE, choose the flash's A-TTL mode, and start shooting,
with no worries about calculating shutter speeds, aperture values or guide numbers.
The A-TTL flash output control system responds automatically to everything from shooting
in very low light to daylight fill-in flash photography. There are five flash units
designed to be used with the EOS-1: the Speedlite 430EZ, 300EZ, and
200E; and the Macro Ring Lite ML-3.

The "A" stands for Advanced. The EOS-1's A-TTL system makes great flash effects easy to achieve. Put simply, this improved system takes the background into account as well as the foreground, so maintaining the degree of illumination you want in both is possible. Pressing the shutter button halfway causes the 430EZ to emit a beam of infrared light. This pre flash measures the distance to the subject. The shutter speed and aperture value are then determined automatically, based on both the background brightness as detected by the camera in the four outer zones of the evaluative metering system, and on the main subject's distance, as determined by the Speedlite's preflash.

| A large LCD panel on the back of the flash displays aperture values that correspond to the operation of the camera, and indicates coupling distance ranges. Moreover, there's lock pin that holds the flash firmly in place and ensures good electrical contact. The Speedlite 430EZ has a maximum guide number of 141 in feet and 43 in meters (at ISO 100). | ||

Back during the original EOS-1 days with other secondary models, the rather sophisticated
Canon Speedlite 430EZ was designed aiming to provide natural-looking flash
photography with the camera. The flash head of the flash can zoom automatically to
deliver the correct amount of light, and the guide number shifts accordingly, too.
The A-TTL mode maintains a natural balance of brightness between the subject and
background, and independent flash output compensation can be done up to +3 stops
in 1/3-stop increments with the flash, as well as with the exposure compensation
capabilities of the camera itself. This kind of control lets you maintain the exact
relationship between ambient light and flash, creating the kind of photographic effects
you want. Second-curtain sync is another advantage. The flash is fired at the end
of a slow shutter speed exposure rather than at the beginning, preserving the natural
flow of moving light. The stroboscopic flash function enables multiple exposures
of a single frame for a fascinating "stop-motion" effect.
Except for
the newer series of Canon SLRs (including the digital SLR models) in some restrictive
functions. the old Canon's Speedlite 430EZ, still offers the performance of any EOS
electronic flash uni to deliver quality flash photography. Standard 430EZ features
include:
* Guide Number 116 (ft.) (ISO 100, 50mm lens)
* Bounce and Swivel Flash Head.
* Internal Automatic Zoom from 2480mm with Manual Override.
* A-TTL, TTL, and Variable Power Manual operation (includes automatic fill-in flash
capability).
* Exclusive Rapid-Fire Flash for quick recycling.
* AF Illuminator for low-light operation.
* Electro Luminescent (EL) Data Display panel.
* Second Curtain Sync.
* Display of aperture value and distance ranges in TTL and Manual Modes.
* Modular Off-Camera Accessories for TTL operation with up to 4 flashes.
As compared to the older, 1987 Canon 420EZ flash, addition of newer features
include: Flash-fill ratio control up to +J-3 full steps in 1/3 step increments. Choice
of power supplies: 4-AA batteries or Transistor Pack E for extended shooting sessions.
A locking pin for secure attachment to EOS 630 & EOS-1. 90 second Automatic Shut
Off (Save Energy [SE] Function). Mode memory: all settings memorized even when main
switch is turned off. Improved Stroboscopic Flash up to 10 flashes per second.

Compatibility with other Canon SLRs. The 430EZ is especially designed for use with the EOS-1 and EOS 630/RT cameras. With other Canon cameras, some features are not available. As an example, the hot shoe lock pin is only used with the EOS-1 and EOS 630. When used with the EOS-1N or EOS-1N RS, A-TTL is only possible in programmed AE mode only. Other shooting modes works primarily in TTL flash |

NOTE: A good consideration for investing into Canon photographic system is: Many Canon system accessories have been designed with great compatibility in mind. The older 420EZ can also be used with the EOS-1 as well as the 540EZ designed for the EOS-1N. The new Speedlite 550EX made for the new EOS-3 camera can also be used with the EOS-1. |
