The Cactus AF 50 is the latest TTL flash unit from Gadget Infinity. This unit has many advanced features that are normally only found in manufacturer specific flashes. It comes in five versions: Nikon, Canon, Olympus / Panasonic, Pentax and Sony Alpha / Minolta.
The AF 50 in general has a very solid feel to it and is about the same size as a Nikon SB600. On the front of the flash is the slave sensor and an auto focus assist red light. The battery compartment is on one side with the wireless sensor on the opposite. The unit also has a built in diffuser and bounce card. One of the more interesting physical feature is the mounting foot. It has a push to lock fastener that does a great job of keeping the flash firmly locked into place.
The flash head has the ability to both bounce ( 0-90 degrees ) and swivel 180 degrees one direction and 120 degrees the other.
