Summary: I can spend all day praising the Metz 58 AF-1. It is a flash that does exactly as advertised in my short term experience with it. With the review above I've shown off what I like about the flash and the features I think most will find most useful. Rather than rehashing those I will touch on the few negatives I listed above.
Summary: It's a great flash and at £267, it's competitively priced against the high end models. like the Nikon SB900 and Canon 580 If you're looking for a separate flash unit with fill options and full TTL and you don't want to pay full whack for a manufacturer's own model then this is the flashgun to get.
Pros: Secondary flash head, Burst rate option, Wide coverage, USB port for online updates
