The Metz Mecablitz 44 AF-1 digital is a dedicated flash for compatible Minolta Maxxum and Sony digital cameras with the proprietary "inside out" mount: it will not fit cameras with the much more common ISO hot shoe. Check your camera's manual to be sure! Minolta Maxxum DSLRs use this foot, as do most Sony DSLR cameras and some earlier mirrorless models; it is not compatible with any currently-produced cameras, including the A7 series. Seems like this whole description is about what this flash will and will not fit (thank you Minolta) but briefly, this flash provides full TTL functionality on compatible digital cameras, and will operate in manual mode, too. It has a tilt & swivel head, a simple button-based interface, and it's made in Germany, whatever that means to you. In excellent condition, with original box and manual.
