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.

Metz is the only flash out there that has a secondary flash built into the front of the unit.

Seconday flash can fill in when used in bounce mode

External AC power pack pricey

Love this flash as it betters the Vivitar 5600, Vivitar 383 and Sunpack 611 that I use to own. it powers down to 1/256th in 1/3 increments. I use a Godox Propac PB 820 to provide extended power.

Output can be electronically adjusted with compensation button

Cost; No dedicated adjustment buttons

I use this flashgun in a wide range of situations including outdoors in sunlight but also indoors. The Metz 58 AF-2 flashgun is superb and it is a much better flash unit than the Nikon SB-910 I think as it does everything the SB-910 can do and it is a lot more powerful plus it's £90 less than...

This Flash light is very easy to use. You just need to attach and It will start its work. Reflector provides flash in enclosed areas. Its LED display on its back shows the photographer about the flash is ready or not and the photo is lIt in accurate manner.

This is a wonderful flash with great output. The recycle time is slower than I am used to but overall I love this flash and will use it as my primary.
