Metz 76 MZ-5 digital flash with Rebel xTi?

[PrimaPhoto]

Yesterday I got my Metz 76 MZ-5 digital flash. Nice flash but I'd like to see if anyone has experience using it with Rebel xTi and the 20D?

Do these 2 models of cameras have ETTL capabilities?
Thanks

Yes, they do. All the Digital EOS models have E-TTL.

you have the Metz 3102 M3 module for your 76MZ5, I presume. That will provide ETTL compatiblity at the flash side of things.

Yes correct. The manual is confusing and all my shots are under exposed?
I've tried M, and Tv mode on the camera.

Examples?

Yes, your wonderful Canon ETTL is telling the Metz 76MZ to discontinue output of light the same as it does with its own Canon 580EX flash -- much too soon! The infernal ETTL logic is impaired, and they carried the underexposure into the new 580EX-II self-contained Auto mode as well, and CurtisN has shown it to be -2EV from proper exposure even when not using ETTL!

I have Metz 54MZ with my Canon 20D, so I know of which I write!

Canon ETTL has a notorious reputation for underexposure when flash is the main source of illumination for a shot, and the remedy that is used by most is to dial in FEC of about +2/3 EV or +1EV for shots where flash is main source of illumination.

An immediate fix is to put the Metz on Auto, and it should do much better than when it is under ETTL control.


But, please do as suggested, and post an example, in the rare case that your problem is induced by one of the many other complications to use of ETTL flash!

thank you for posting this!!!!! i've gotten frustrated with my 420EX on several occasions and what you describe seems to be the root of it...i would pull off the 420EX and use the on camera XTi flash and get much better flash exposure...it was very confusing. gonna try the +2/3 FEC on my next shoot. ;)

Indeed, try the flash in AUTO just to see if there is a difference. I rarely use my metz 54 in the TTL modes as AUTO is much more reliable.

;) - Yes the info is correct, I set the flash to Auto and use Av mode on camera and it makes a big difference (with no EV).
