Score: 78/100
Photoolex FK310
Score: 78/100Rankings

The Yongnuo YN560 IV is a budget-friendly manual speedlite that doubles as a 2.4 GHz radio transmitter, offering solid output and long wireless range for photographers comfortable with manual control. Its lack of TTL, HSS and reliance on AA batteries limit its appeal for fast-paced or fully automated shooting.

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.

Professional reviewers praise the YN560 IV for delivering a feature-rich manual flash at an unbeatable price, highlighting its integrated wireless transmitter, solid construction, and dependable output, while noting the trade-off of missing TTL and HSS.

Professional editors view the PHOTOOLEX FK310 as a solid manual flash aimed at enthusiasts and semi-professionals who value precise control and extra features like an LCD panel, while noting its lack of TTL, HSS and built-in radio wireless.
Users like the strong output, intuitive LCD and included accessories, but miss TTL automation and report occasional issues with optical slave triggering on newer cameras.
“Dual functionality as flash and wireless transmitter is a game changer.”

“Great for budget-conscious shooters, but wish it had TTL.”

“The radio range is impressive, but the AA batteries are a hassle.”
