Photoolex FK310
Score: 78/100Rankings
The Metz mecablitz 64 AF-1 is a high-power, feature-rich speedlight for Sony/Minolta systems, offering a GN 64, fast recycle, secondary fill flash and a full-color touchscreen, but it is heavy and can overheat under heavy use.
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 64 AF-1 for its unmatched power, solid construction, and innovative secondary fill flash, while noting the steep learning curve and lack of a battery indicator.
Everyday users rate it highly for power and durability, appreciating the bounce-fill tube and touchscreen, but they frequently mention overheating and the missing battery-level display as drawbacks.
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.
“Most powerful and sturdiest flash I own”
“Works flawlessly with Nikon and Sony DSLRs (even cross-brand)”
“The touchscreen is appreciated once mastered, but the menu can be overwhelming”
