The Ikelite DS125 strobe is preflash compatible and provides optimum performance

with traditional film cameras, digital still cameras, and dSLR cameras in related Ikelite

housings. The appropriate sync cord or sensor must be connected to trigger the strobe.

The TTL/Auto exposure mode on the Ikelite DS125 strobe is compatible with the

following TTL film camera systems. The camera reads the light passing thru-the-lens

and automatically signals the strobe to turn off when the exposure is correct.

Many Ikelite Digital Still Housings and Ikelite dSLR Housings feature TTL compatible

circuitry connected with the Ikelite female bulkhead connector. Connect the Ikelite sync

cord from the Ikelite housing to the DS125 strobe for TTL auto exposure.

Some other Ikelite housing models may feature the Ikelite bulkhead connector but

offer only manual exposure because TTL conversion circuitry for that specific camera

model may be unavailable or not yet developed.

Some digital still cameras feature a small built-in flash

a means to connect

a sync cord for an external strobe. Most of these cameras fire their built-in flash more

than once while taking a flash picture. This happens so fast it is difficult to see, but the

preflash helps the camera determine focus, exposure and color balance. After the

preflash, the camera’s built-in flash then fires to illuminate the subject and the picture

is taken. For the external strobe to provide proper exposure, it MUST be preflash

compatible to duplicate the preflash sequence. The Ikelite DS125 strobe is a

strobe.

For those cameras that do not offer a means to connect a sync cord, the optional

Ikelite DS Sensor #4100.5 may be compatible to trigger the DS125 strobe. Built-in slave

sensors in the DS Sensor detect the light output from the camera’s built-in flash and

automatically signal the DS125 strobe to mimic the output by starting and stopping

automatically. However, some of the newest digital still cameras feature a preflash

sequence too quick for the Ikelite DS Sensor to identify proper auto exposure, and the

Ikelite EV-Controller #4100.6 would then be recommended instead.

For maximum control using manual exposure, choose the optional Ikelite

EV-Controller #4100.6, which connects to the DS125 strobe and provides 10-manual

power settings in half-stop increments. The EV-Controller can be triggered using the

built-in slave sensor or by connecting an optional sync cord.

Most newer cameras and strobes feature TTL/Auto exposure, which automatically

compensates for aperture, distance, extension tubes, and filters. Considering the wide

range of apertures and subject distances, select the TTL/Auto exposure mode to easily

control balanced lighting and close-up photography.

When the strobe fires, the camera reads the light and automatically signals the

strobe to turn off when the exposure is correct. Both the strobe and camera must

feature TTL/Auto exposure compatible electronics. The appropriate TTL sync cord or

optional Ikelite DS Sensor is required to relay the TTL/Auto exposure signal from the

camera to the strobe.

Please review the "Compatible Camera" section on the previous page for additional

information.

Ikelite offers interchangeable sync cords so that different camera systems can be

connected to the DS125 strobe. A TTL sync cord is required to send the TTL/Auto

exposure signal from the camera to the strobe.

The Ikelite DS Sensor provides auto exposure functions through slave sensors

enabling the Ikelite Substrobe to be moved freely and positioned virtually anywhere.

The DS Sensor connects only to Ikelite DS Substrobes and detects when the light from

the TTL strobe connected to the camera starts and stops, and automatically signals the

Ikelite Substrobe to start and stop in sync.

Many digital still cameras feature a small built-in flash without a means to connect

a sync cord for an external strobe. For these situations, the optional Ikelite DS Sensor

#4100.5 may be compatible to trigger the DS125 strobe. The sensor detects the light

output from the camera’s built-in flash and automatically signals the DS125 strobe to

mimic the output. Some of the newest digital still cameras feature a preflash sequence

too quick for the Ikelite DS Sensor to identify proper auto exposure, and the Ikelite

The DS125 strobe should NOT be continuously fired more than 15 times in rapid

succession. In such instances, allow the DS125 strobe to cool off for at least 10 minutes.
