Olympus STF-8 Twin Macro Flash

I've been using this twin flash for close-up insect shots, and the way it balances light on both sides of the subject makes a huge difference. The compact size means it doesn't weigh down my camera setup at all, and it's held up fine in a light drizzle.

The weather sealing is exactly what I needed for outdoor macro shots in damp conditions—no worries about moisture getting in. It's compact enough to leave mounted on my camera in the bag, and the twin lights give me even illumination on small subjects. Definitely a solid upgrade from using a pop-up

Finally, a macro flash that doesn't feel like a brick on my camera, and being dust- and splashproof means I don't have to baby it on outdoor shoots. The twin heads give me just the right amount of control to light up a tiny flower petal without washing it out.
