A couple of days ago my order for a Metz 58 AF-1 hotshoe flash came in the mail. After allot of research I opted to get this flash for my Canon 30D, rather than the 580EX II. Why ? Well, I had some bad experiences with 2 previous Canon flashes which tended to underexpose by 1 or 2 f stops. The metz 58 came with a carrying pouch a stand and of course a manual. The first thing I noticed was that it wasn't as rugged as my 550EX never mind the 580EX II, which I heard is built like a tank. The 58 is much smaller, lighter and flimsier, a little too flimsy for my taste, but what the heck, time to check out some of those features. I quickly inserted 4 Alkaline 1.5 volt Duracell batteries in the chamber and began firing away. Everything seemed to be working properly in ETTL mode just like with my 550EX. The camera operates through some push button menu system that some bloggers complained loudly about while I was doing my research. At first it was a little annoying pushing all those buttons, but after a while you get used to it. The good thing is that when you first push a button, the LCD lights up, then you got to push the button again to nagivate through the system. There are some up/down arrows and +/- sign that allow you to set the flash. For example if you want to set the Mode(ETTL, Manual, Automatic, Strobe) you press the mode button which lights up the LCD and also displays the up/down arrows that let you choose which mode you want. To get to the 'A' or Automatic mode, you have to push the button right below the down arrow on the screen. I hit the 'down' arrow two or three times, which put me in the 'A' mode then hit the'set' button and now the flash was set to "Automatic". Automatic mode is different than TTL, or ETTL, or ATTL. It was the method used in older flashes, prior to TTL, when the tryistor measured the amount of light that reflected off a subject and cutt-off the flash when it determined the subject was well lit. The Vivitar 283/285 used thryistor technology. The reason why I wanted this function is that ETTL often gets fooled when you have highly contrasting subjects such as a guy in a black tuxedo and a gal in a bright white wedding gown. Anyway, I set the flash to 'A' mode for automatic and then set the camera to 'P' mode also automatic(sound confusing ?). I then tried to set the camera to the aperture/shutter speed I thought might give me the better shot. For some strange reason everytime I hit the shutter button the camera and flash would be set to F22 @ 1/250. No matter what I tried pushing all the buttons, changing the batteries, going back to reading the manual, turning the flash on and off, it would revert to the same settings F22 with a shutter speed of 1/250 sec. Finally it dawned on me that Automatic is usually done in Manual mode, so I set the camera to 'Manual' mode and now the flash and camera were in sync. Paranoid, I wrote to the folks at Metz concerning the F22 @ 1/250 sec in 'P' mode and they told me that all Canon SLRs can only handle Automatic mode in 'M' and 'AV' mode. The F22 @ 1/250 is a default the camera puts out because it cannot handle it. Before the folks at Metz got back to me, I had already written B&H about this problem, but the salesman I talked with just gave me a long lecture on why I should have gotten the 580EX II. I even talked to the folks at Bogen in New Jersey and they told me the Flash was faulty and to send it in. Since I was still under the 15 day B&H return policy, I was going to trade the flash in for a 580EX II and call it a day, until I received the email from Metz. To keep a long story short, so far I'm very happy with this flash. It has all the features I want and the exposures are dead on. I'm not saying it's a huge improvement over the 550EX, but it's peace of mind,(so far). The only thing I just wish it wasn't so flimsy.
