Neewer 10084512 CellsII-C Wireless Flash Trigger for Canon EOS

The Neewer CellsII-C is an all-in-one wireless transceiver designed specifically for Canon EOS camera systems, functioning as both transmitter and receiver in a single unit via a TX/RX mode toggle. Its headline capability is high-speed sync support up to 1/8000s — a specification that matters most to photographers working in bright ambient conditions who need to use wide apertures for shallow depth of field while balancing flash fill. Achieving that 1/8000s ceiling requires alignment between the camera's maximum mechanical shutter speed and the flash's IGBT-based duration; when both conditions are met, the CellsII-C removes the trigger as the limiting factor. The multi-channel design allows multiple units to operate in the same space without cross-triggering — a practical necessity in workshop or multi-photographer environments.

The CellsII-C is built for Canon EOS photographers working within the Neewer flash ecosystem — portrait and event shooters using TT-series speedlites or Neewer studio strobes who want reliable wireless triggering without the cost of a higher-end radio system. The all-in-one form factor is a genuine operational advantage: in a kit where every unit can be either a transmitter or a receiver, you carry fewer single-purpose accessories and have more flexibility when your setup changes on the fly. The trade-offs are those common to entry-level triggers: no TTL, no remote power adjustment, and a compatibility envelope that narrows outside the Neewer product family. For shooters who set manual flash power and want a dependable, lightweight way to fire remote flash from a Canon EOS hotshoe, the CellsII-C delivers on that specific brief.
