The Canon Speedlite 430EX II Flash is Canon's mid-range shoe mount flash, yet it offers many of the same advanced features as its bigger brother, the 580EX II. It is designed to fully support the entire range of Canon digital SLR and G-series cameras. The Speedlite 430EX II Flash is compatible with Canon's latest E-TTL II (Evaluative Through The Lens) auto exposure technology. When combined with a compatible Canon camera and compatible lens, E-TTL II utilizes subject distance and other information that automatically modifies flash power, resulting in accurate flash exposure regardless of subject size, reflectance, or photographic composition. This is great for photographers that shoot high contrast or reflective subjects, like those encountered in wedding photography. Photographers can now capture every detail from the black of tuxedos to the white of wide smiles and wedding dresses.
