Excerpt: I previously purchased the Panasonic FL360 & 580 flashes, and they are not up to the demands of professional wedding photography. After experiencing a broken (plastic) foot on an FL360 and getting nowhere with Panasonic support after months of trying to purchase a replacement part, I gave up. Being used to the Canon pro flashes, including owning multiple EX600 RT's, before switching to M4/3 systems, I wanted a powerful, high-end on camera flash.
Pros: Bounce Flash, Consistent Output, Easy To Use, Powerful Output
Excerpt: Added a stroboframe 350 to my Pentax K-5 then the Metz 58 AF-2 set to Auto mode. The K-5 is not known for reliability when it comes to speedlights but the Metz gets the job done. My newer model K-3 is in the shop but I can't wait to try the Pttl mode.
Pros: Consistent Output, Easy To Use, Fast Recycling, Powerful Output, Versatile
Excerpt: Looking for an alternative to the thermal shutdowns of a Canon Speedlite 600EX-RT, I purchased the Mecablitz 58 AF-2 for use on a EOS-1DX. In that respect, it's been operating without issues, in heavy use with a Gary Fong diffuser. I have, however, found the E-TTL exposures to be less consistent than that of the Canon Speedlight. The front facing 'wink light' works nicely under the right conditions.
Pros: Durable, Fast Recycling, Lightweight, Versatile
Excerpt: I won't get into all the technical aspects of the Metz 58 AF-2, because that would be a chore for any of the high end flashes. My basic uses are weddings and events. The Metz 58 AF-2 has an easy to learn menu with a quality of light that is exceptional. This is one of the top two flashes in the world, giving a benefit of doubt that there is one better.
Pros: Consistent Output, Easy To Use, Powerful Output
Excerpt: The Metz 58 af-1 is a very good flash, but this 58 af-2 for Canon has got to be considered one of the best flashes on the market. After only taking two photos I knew I made the right choice. The light quality is exceptional. Colors are saturated and defined. I use mine mostly for weddings and events. My flash bulb blew up on the 58 af-1, which wasn't unusual for that model. The reviews say this one more durable. I hope so.
Pros: Consistent Output, Easy To Use, Fast Recycling, Lightweight, Powerful Output
Excerpt: Using this unit with a Quantum battery. Unit works nicely with my D800; no compatibility issues. Since I get to use the high power port (to connect my battery), I wish this was located in a more efficient location: when the external battery power cord is plugged in, the cord itself gets in the way while trying to look through the viewfinder.
Pros: Consistent Output, Easy To Use, Lightweight, Powerful Output
