Powerextra DF-400
Score: 54/100
Photoolex FK310
Score: 78/100Rankings
The Photoolex FK310 LCD Speedlite adds an LCD panel and a rich accessory set to the solid GN33, 22-level manual flash platform, but it still lacks TTL and high-speed sync.
The Powerextra DF-400 is a budget-friendly manual flash offering basic power control, optical slave modes, and a rotating head, suitable for beginners and hobbyists. It lacks TTL, HSS, and a robust build, making it less ideal for demanding professional work.
