The New Metz 58 AF-1 digital is one of the most state-of-the-art compact flash units available today, the 58 AF-1 digital gives photographers the ability to effortlessly make software updates via the Internet. Previously, flash units needed to be packaged and sent away for servicing in order to be updated with the latest software from camera manufacturers. With the new Metz USB interface, shooters can now make such updates from their own PCs, ensuring that they will have the most up to date and highest performing flash for each shot and that they will never have to be without a flash.
