Photos: Updating the firmware on the Metz 58 AF-1
First of all check to see if you have the latest version of firmware installed, to do this just turn on your flash unit.

Then head on over to the Metz firmware download page and then download the latest firmware.

Click on your appropriate platform. For this example I will be updating via Windows.

Once downloaded to a location like your desktop open the file.

You will get a Windows Security warning so go ahead and click on Run.

The program will automatically extract the files into the current folder.

There will be 2 files and 1 folder where all the files are needed to update your flash unit.

Run the FirmwareUpdate_MB58_GB.exe.

Of course you’ll have to accept the Terms of Use first.

Go ahead and hit the Start button. If you do not have the flash unit plugged in now you will get the following message:

So please have the flash unit plugged in before you start the firmware upgrade. You will need a USB cable with a Mini-B connection to hook up the flash unit. Also you do not need batteries in the unit when performing the upgrade.

Once you hit Start, you will see a blue progress bar at the bottom right hand corner. The entire process takes about 15 seconds.

Once the firmware has been downloaded to the flash unit the program will automatically verify the files.

After another 15 seconds or so the verifying will be done and your flash unit will have the latest firmware.

I hope you enjoyed reading this. If you are interested in any other type of guides please feel free to comment below and if I have the capability I will try to do the write up!
I have updated my 58 AF-1 mecablitz, but how I face problems with batteries. They are empty after 2 shots (GP 2700). I have a Nikon D7000 camera. The flashlight is now useless for me.
Anyone faces the same problem?
Hi Stephen,
I have not tried the GP 2700 batteries as I am in the States. Have you tried other LSD batteries such as eneloop or Duracell? Also have you tried using regular alkaline batteries and see if you get the same results?
