The Canon Speedlite flash will first automatically detect how for away your subject is, and then fire a few test flashes to find the perfect spot for bouncing the flash in the current room you’re in. You can then zoom, focus, and adjust your settings to your need and fire when ready to activate the flash in the spot it thinks is the best.
If and when you change the orientation of your DSLR camera, the Speedlite will also automatically adjust itself as well. Just give your shutter 2 quick half taps to have it auto-adjust itself to the new orientation.
There are a few different settings to the automatic flash bounce attachment such as a mode to automatically readjust the flash in real-time as you move the camera around, a single-tap or double-tap adjustment mode, or you can turn it into a completely normal manual flash for professionals that don’t need to AI assistance.
A perfect gift idea for photographers, the Canon Speedlite auto-flash is compatible with type-A EOS cameras (E-TTL II/E-TTL autoflash), and with type-B EOS cameras though, only manual flash and second-curtain sync are possible. The flash can be used up to 140–966 flashes per charge, and is best when used with 1900mAh type AA/HR6 Ni-MH batterie.
The Canon Speedlite not only comes with the auto-intelligent flash, but it also comes with a VIVITAR 4-Port Overnight Charger with 4 AA Batteries, an Altura Photo Universal SoftBox 6×5” Flash Diffuser, an Altura photo 50 Sheets Camera Cleaning Tissue, an Altura Photo Cleaning Kit, along with a Premium MagicFiber Microfiber Lens Cleaning Cloth.
