The ST-IV+ supports both TTL auto-exposure and High-Speed Sync (HSS), which enables you to use your flash at shutter speeds up to 1/8000s. The ST-IV+ remote flash trigger now features Bluetooth support allowing it to be used in conjunction with the GODOX Flash Smartphone App. This enables you to control the power of your flashes with your smartphone through app control, ideal for situations where the trigger on your camera cannot be easily accessed. With its large screen dedicated group buttons, and user-friendly interface, the ST-IV+ is the perfect remote flash trigger for any professional photographer. This trigger is available for Canon, Nikon, Sony, Olympus/Panasonic, and Fuji (Also available for Leica).
Through The Lens Auto-Exposure
The PixaPro ST-IV+ supports "Through The Lens" (TTL) auto-exposure when used with TTL-capable flashes. The trigger works with your camera to determine great exposure automatically. This leaves you able to concentrate on taking photos. Perfect for fast-paced shooting scenarios such as weddings, and photojournalism.
High-Speed Sync Support
The ST-IV+ remote flash trigger supports both TTL and High-Speed Sync (HSS), enabling you to use your flash at shutter speeds of up to 1/8000s. HSS enables you to kill excessive ambient lighting. Perfect for times when you want to shoot outdoors with a wide aperture, but do not background to become blown out.
32 Channels and 99 Channel IDs
The ST-IV+ wireless flash light trigger features 32 Channels, and 99 Channel IDs. This allows you to remotely control and trigger any compatible flash set to the same Channel and ID at any time. Channel IDs are ideal for situations where there are multiple photographers shooting at the same venue/event, using similar flashes. Channel IDs also reduce the risk of RF interference from other devices.
Multi-Shoot Mode
The Multi-Shoot feature enables multiple photographers to trigger and control the same set of flashes. In Multi-Shoot mode, your ST-IV+ remote flash light sends your flash settings to the light, and the flash will operate according to the setting you have set on your trigger. Ideal for use at weddings with multiple shooters, and group photoshoots.
Godox Flash App Compatibility
The PixaPro ST-IV+ wireless flash light trigger features Bluetooth connectivity, enabling it to connect with the GODOX Flash Smartphone app. Perfect for times when your camera is in an area that is not easily accessible. The app enables you to control the output of your flash remotely with your smartphone, using its clear, easy-to-use interface. The Godox Flash App is available on the App store and the Google Play Store.
Sekonic L-858D Compatibility
The ST-IV+ 2.4GHz wireless flash light trigger with App Control is compatible with the Sekonic L-858D with the GODOX 2.4GHz module. This enables you to adjust the flash power using the light meter and fire the flash when taking a meter reading. Ideal for professional photographers who work in busy commercial studios (Sekonic L-858D light meter available separately).
TCM Feature
The ST-IV+’s TCM enables you to take a TTL exposure, and then convert it into a manual exposure. This feature can be used if you are happy with an exposure that the TTL metering has given you, and you want to lock it in place, or it can be used as a makeshift light meter.
Scan for Best Channel
The ST-IV+ remote flash trigger now features a Scan for Best Channel feature, which scans the airwaves, letting you know which channels are the clearest to use. This reduces the likelihood of running into RF interference and possibly getting misfires.
Single-Pin Mode
Single-Pin mode enables you to deactivate all other communication pins on the hot shoe, except for the central firing pin. This enables you to safely use the trigger with other camera brands in manual mode.
The Pixapro ST-IV+ wireless flash light trigger is the perfect update to an already great flash trigger. The addition of Smartphone App control and added compatibility with the Sekonic L-858D Flash Meter with GODOX 2.4Ghz module. Along with the other new features such as Scan for the best channel, the ST-IV+ is the perfect flash trigger for photographers who like the larger screen of the ST-IV, but also want access to the ability to scan for the best channel, or want to use their trigger with the smartphone app.
