This lens-mounted ring flash with hot-shoe controller is ideal for macro photography, product imagery, flat-lighting portraits, and medical/dental applications. It provides smooth, even lighting for the closest subjects, while eliminating vignetting and subject shadow.
Guide number 53 at ISO 100/ft (16 at ISO 100/m) provides ample lighting for small or large close- focus subjects.
Modelling light with 4 white LEDs help preview flash exposure while assisting autofocus operation.
Compatible with P-TTL, TTL, and manual systems.
P-TTL exposure compensation available (+0.5 to -1 in 1/2 stop increments). Manual flash operation at full, 1/4, and 1/16 power.
The kit includes lens adapter rings for 49mm, 52mm, 58mm, 67mm filter threads, as well as a macro adapter for PENTAX D-FA series macro lenses.
