The metz 58 AF-2 is a excellent flash, it has some nice advantages over the canon. The secondary filler flash is one of the nice things it has. The user interface is easier to use. And the user upgradable firmware is nice. You can set it up adjust for aps-c or FF cameras.
The metz have had no issues on my t1i, 60D or eos 1. Does not misfire.
I have the metz 58 AF-2 and the older metz 48 AF-1 (replace my the 50 AF-1) and they have been solid performers.
Super Frequent Flyer, no joke. Ex Patriot and loving it.
