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 Godox TT520II is an affordable manual speedlite with built-in 433 MHz radio, offering solid wireless performance, tilt-and-swivel head and integrated diffuser, but it lacks TTL/HSS and a display, making it best for beginners and budget-conscious shooters.
