This is a compact strobe for the EOS DIGITAL series. It uses two AA batteries, so I mainly used it for travel and snapshots. It's small and lightweight, so it's convenient to have in your bag when you need more light. There are no noticeable scratches, but there are some minor scuffs. The manual zoom allows you to switch between a guide number of 22 (for a 28mm focal length) and a guide number of 27 (for a 50mm focal length, ISO 100・m). It also has a bounce mechanism that allows you to reflect the strobe light off the ceiling. The bounce angle can be set in three steps upwards (60, 75, and 90 degrees). Both normal flash and bounce flash functions work without any problems. Metering System: Compatible with E-TTL II/E-TTL EOS bodies. Included accessories are the original box, soft case, and instruction manual. Here are some specifications: Guide Number: 27 (ISO 100・m) Bounce (Upward): 60°・75°・90° Power Source: 2 AA alkaline batteries (rechargeable Ni-MH batteries also acceptable) Size: W64 x H65 x D76.5mm Weight: Approximately 145g (without batteries)
