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.

Excerpt: Metz (or Mecablitz) may be an unfamiliar name to a lot of you but for many decades its been the workhorse flash for a lot of pro photographers around the world. Metz is made in Germany and marketed in the US by Bogen Imaging Inc. www.bogenimaging.us I used to sell a lot of Metz strobes at the camera stores I worked at and over the decades came to appreciate their quality and durability.
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
