Score: 78/100
Godox iM30
Score: 68/100Rankings

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 iM30 is an ultra-compact manual speedlight powered by two AAA cells, offering basic flash functionality and optical slave modes. Its portability is offset by low power, no TTL/HSS, and a fixed head, making it suited for casual or travel use rather than demanding studio work.

Products in the top-left offer the best value (high score, low price).

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.

Professional reviewers commend the iM30 for its nostalgic retro styling, ultra-compact form factor, and intuitive tactile dial, but stress its low guide number, lack of bounce/swivel, and absence of TTL/HSS for demanding work.
Everyday users love the tiny size, vintage look, and AAA convenience, but are frustrated by the missing battery indicator, slower recycle, and harsh light from the fixed head.
“The LCD makes setting power levels a breeze.”

“Great value with all the accessories included.”

“Wish it had TTL for faster shooting.”
