The Godox's TT685C II Flash makes it easy to create both simple and elaborate lighting setups, offering full support for Canon E-TTL/E-TTL II and a built-in 2.4 GHz radio system. This flash has a powerful guide number of 197 at ISO 100 and a zoom range of 20–200 mm, making it a powerful and effective lighting tool. The TT685C II is a full wireless master or slave unit with TTL functionality, and it tilts from -7 to 120 degrees and rotates 330 degrees for maximum versatility, giving you more flash angles and a more efficient lighting setup process.
