Automatic single-speed shutter

though the image makes it look a bit reddish (blame a weak IR filter on our camera) Internal dimensions of the insert are approximately are 7x22x26cm

Yongnuo YN560 &nbsptype_Projectors Automatic single-speed shutterThe Yongnuo YN 560 looks like a Canon 580EXII, but it's not: it's a simple, single pin, non TTL flash suitable for on or off camera use (yes, it does have a PC sync connection). The head tilts and swivels, and zooms from 24 105mm coverage. In very good condition, with minor cosmetic wear. Compatible with any camera that has a hot shoe, film or digital.
