The ADI flash metering incorporates guide number control in Minolta's superior TTL 4-segment flash metering, further enhancing flash metering performance. With the ADI flash metering, precise exposure is available virtually regardless of the background conditions or the subject reflectance. The HS D fires a pre-flash, the returned reflection from the subject is interpreted by the segment Honeycomb-Pattern cell, and the data is factored in the calculation of final flash output, further enhancing the precision in flash photography.
With it, the photographers can take the full advantage of a large-aperture lens with a shallow depth of field in daylight photography while enjoying the freedom to create unique and exciting images without usual tangle of accessory cords or connectors. Hold Switch The HS D offers a function to prevent the current flash settings from being accidentally changed.
Turning the hold switch on the unit only accepts test firing and data panel illumination while locking other flash settings. EL Lighting The EL electroluminiscent data panel provides uniform lighting to ease photographing in the dark. Low-Battery Indicator A low-battery indicator appears in the data panel when the remaining battery power is low.
With High-speed Sync, the photographers can take the full advantage of a large-aperture lens with a shallow depth of field in daylight flash photography. Attach the HS D to the camera and switch the flash and camera power supplies on.
Set the camera to wireless flash. See the cam- era manual for details. Page Using Two Flash Units 5. Press the select button repeatedly until blinking stops. See the flash manual if using the HS.

Use of the extension cable allows of the distance from the camera to be further extended. Leakage from the batteries may damage the battery chamber.

While you can pop alkalines, lithiums or Ni-MHs into it, performance varies depending on the power source. Konica Minolta manufacturers a number of accessories for this unit, including an off-camera cable, off-camera shoe to match the proprietary connector to standard hot shoes , extension cable and a cable CD and triple connector for multiple flash units.
An external battery pack holding six AA batteries reduces the charging time by half and doubles the number of flashes possible. And a bounce reflector set V includes an adapter and a large fabric reflector that folds up for transport. Along with the flash unit itself, Konica Minolta includes an attractive leather-like case and a small stand that adds not only feet but a tripod mount to the HS. The front of the HS is dominated by the flash head's lens and flash tube at the top.
On the left side of the unit looking at it from behind , the terminal cap with its accessory terminal and external power terminal sits above the mounting foot release button.
On the right side, the head contains the bounce lock release button while the body features the battery chamber door. On the back, the head has an engraved bounce angle scale.
The body is dominated by a large black and white LCD data panel below which is a control panel of a number of buttons. The control panel's first row of buttons consists of the Mode button, Select button, Minus button and Plus button. Below the Test button is the Test mode switch, offering four options.
Getting a grip on wireless flash is something of a goose chase. There's the flash manual, which often defers to the camera manual. And the camera manual, which can't speak for the flash. Phil had helped us find a few accessories. It turns out that the HS behaves quite differently with the 7D than it does with a Maxxum film camera. All exposure computing is done before the shot is taken.
When you press the shutter button on the 7D, Phil explained, a series of 14 preflashes are fired, one for each of the 7D's 14 metering segments. The segment exposure sensor reads the reflected light and the exposure computer factors that information in with the Subject Focus distance and position reported in the viewfinder, the ambient light brightness and the Distance if a D lens is attached.
The calculation also considers how much of the flash's capacitor is required for the right exposure. Then the shutter release sequence starts, raising the mirror, closing down the aperture, opening the shutter and firing the flash at the calculated percent of its power.
The release sequence starts, mirror lifts, aperture closes, shutter opens and the flash fires 76 percent of its power. Bright scenes can make it impossible for the HS to detect the signal from the built-in flash. Consequently, Konica Minolta recommends using wireless for interior or dark scenes rather than outdoor fill shots in bright sun. You can, however, get nice fill shots in shade outdoors. Konica Minolta makes it pretty simple to get the 7D and flash into wireless mode.
Just attach the flash to the camera's hot shoe, turn them both on and set the camera's flash to wireless. That will also set the flash to wireless mode and set the camera to the flash's wireless channel. You can then remove the flash from the camera and activate the built-in flash by raising it up so it can communicate with the HS. Without a cord to tether you within range of the flash, you can move freely around the subject. But you do have to keep one angle in mind.
Setting the shutter speed is something of a puzzle. Buckle up. Since the strobe is making the exposure, not the shutter, there isn't any advantage to Anti-Shake unless you're using the flash for fill. But this is all moot if you enable HSS -- high speed sync -- on the flash.
HSS uses a preflash, Phil explained, to determine the brightness of the set of strobe bursts to keep up with the shutter when it's moving at speed above flash sync speed.
Rather than fire an intense burst of light for a very short time, the HS sends a series of smaller bursts in HSS mode. You can also set the ratio of the HS on the unit itself to be either half or twice the power of a second external unit. But this is option if off when using just the built-in flash which is used exclusively to communicate with the HS.
We tried a number of studio shots using the built-in flash to trigger the HS remotely in both direct and bounce positions.
