3D Multi-Sensor Balanced Fill-Flash 3D Multi-Sensor Balanced Fill-Flash can be performed only with a combination of F5 camera, D- or G-type Nikkor lens and Nikon SB-50DX/SB-28/SB-28DX/SB-27/SB-26/SB-25 AF Speedlight. In this flash mode, just after you depress the shutter release button and before the shutter is activated, the SB-50DX/SB-28/SB-28DX/ SB-27/SB-26/SB-25 will fire a series of imperceptible pre-flashes (Monitor Pre-flashes) that are detected by the F5's TTL Multi Sensor, then analyzed for brightness and contrast. Furthermore, it integrates Distance Information from the D- or G-type Nikkor lens in use, with other exposure control information, to automatically compensate the flash output level so that flash output and ambient light are balanced. The Monitor Pre-flashes enable 3D Multi-Sensor Balanced Fill-Flash to ensure a correct exposure even in difficult situations, including scenes with a very reflective object such as a mirror or a white wall, or scenes with a very dark background. 3D Multi-Sensor Balanced Fill-Flash can be performed with the Matrix or Center-Weighted Metering. Multi-Sensor Balanced Fill-Flash When the F5 camera and SB-50DX/SB-28/SB-28DX/SB-27/ SB-26/SB-25 are used with a non-D/G-type Nikkor lens, MultiSensor Balanced Fill-Flash, which offers the same flash output control system but without Distance Information, is performed. Multi-Sensor Balanced Fill-Flash can also be performed with the SB-24 and other dedicated Speedlights that do not have the Monitor Pre-flash feature. Center-Weighted Fill-Flash This feature can be used with all AF Nikkor lenses. Use CenterWeighted Metering to determine the ambient exposure control settings, and the F5's TTL flash sensor will automatically control the flash output for a balanced fill-flash effect. Experiment by determining which brightness value you want to use for the ambient exposure setting and which flash compensation setting you want to use. This combination of features enables you to maintain exceptional control over the system, yet allows the system's automation to work for you at the same time. Standard TTL Flash In standard TTL flash, automatic flash output level compensation is not available. This means that, even though the main subject is correctly exposed, the background may not be. With SB-50DX, SB-28/28DX, SB-27, SB-26, SB-25 or SB-24, standard TTL flash offers manual selection of the flash output level compensation instead of having the computer do it automatically. So, with SB-50DX, SB-28/28DX, SB-27, SB-26, SB25 or SB-24, you can intentionally cancel Automatic Balanced Fill-Flash by pressing the Speedlight's M button (or MODE button with the SB-50DX/SB-28/28DX). 110
