This is a speedlight I bought a few years ago for a PENTAX SLR camera. I've only used it a few times for indoor photography, so it's in good condition. Since it doesn't have TTL functionality, you'll adjust the light output manually, but I think you'll get the hang of it as you adjust while taking test shots. 【Condition】 ＜Appearance＞ It's clean with no noticeable scratches. The LCD screen still has the protective seal on it. ＜Operation OK＞ I checked the flash. I confirmed that the light output changes in stages with flash control, and that the internal light-emitting element moves back and forth according to the zoom. 【Accessories】 4 AA batteries, Protective bag, diffuser, stand, English and Chinese manual 【Specifications】 - Guide Number: No. 58 (ISO 100, 180mm) - Flash Modes: M/MULTI/S1/S2 - Manual Zoom: 18-180mm, Super-fast charging recycle: approx. 2.9 s - Wireless Trigger: S1 / S2 wireless induction flash lighting - Light Sensor Trigger Distance: Indoor 20-30 meters, Outdoor 10-15 meters - Vertical Rotation Angle: -7 to 90 degrees, Horizontal Rotation Angle: 0 to 180 degrees - Color Temperature: 5500K - Flash Duration: 1/200s--1/20000s - Recycle Time: approx. 2.9 s - Number of Flashes: 100 to 1500 times - Flash Control: 1/128 - 1/1 (0.3EV steps), a total of 22 fine-tuning stalls - External Interfaces: Hot shoe, PC sync port, external charging port - Power Supply: 4 x AA batteries - Additional Features: PC synchronous, power save mode, over-temperature protection ※ Does not support TTL and camera menu setting functions.
