Step by Step: Fix a Phottix Mitros+ broken zoom

I broke my flash the other day whilst photographing a house in Applecross but before I go into the "How to fix it", let me tell you what happened first otherwise you can skip to it here. It was a calm day and all of a sudden, the clouds came in covering my beautiful natural light that was washing into the bedroom window!

Pressed for time, I decided to just make my own beautiful natural light. I placed a Phottix Mitros+ flash outside the bedroom window with a 32" shoot through umbrella (1/2 CTO Gel), on a 2.5m light stand and ran back in. Before I could press the shutter button, I heard a loud THUD!

I walked outside to see my $400+ speedlight on the concrete floor... Damn you wind!! But I can't blame nature, it was my fault for not securing the light stand in the first place. Picking the device up, I pressed the 'test' button to see if it was still functioning and IT DID!!... You tough cookie! But then when I cycled the 'zoom' function, there was this really loud whirring sound and the flash tube wasn't moving! No biggie at this point, as zooming the flash head wasn't as critical so I proceeded with the shoot.


Still... I was and pretty devastated that my flash zoom feature doesn't work anymore and of course I use that feature quite a lot, so instead of paying a good $50+ to ship it back to the US, I attempted to fix it myself. I documented the process, so for those who have suffered or may suffer from the same problem, you can fix it too!

*Try at your own risk! It voids the warranty and may kill you in the process due to the high amount of electricity the flash capacitor holds.

Step by Step: Fix a Phottix Mitros+ broken zoom

What you need:

  • #0 philips head screwdriver (Stanley does not specify the size)
  • 2.0mm flat head
  • 1.4mm flat head (optional)
  • pair of rubber gloves (my sister's dish washing gloves)
  • pair of tweezers

equipment needed

 Step 1: Carefully pry open the rubber pads on the hinge of the flash head.

Step 5: Now you can carefully detach the bottom cover of the flash and have access to all the components of the head. Firstly, remove the Fresnel Lens.

[one-half-first]Step 10: Realign the zoom rail hook on the flash tube piece back onto the brass coloured platform on the zoom rail. Initially I thought that you needed to glue it back but that isn't the case. It just sits on there... Phew![/one-half-first][one-half]zoom rail hook and platform[/one-half]

Step 11: We have solved the problem! now work backwards to fit all the screws and pieces back together. It's really simple so there is no need for me to show you how.

Important: Make sure you stick the rubber padding back in the right position (hint: there's a small dip where the small tab goes).

Well, I'm happy that I just saved myself $50+ postage and the additional labor and parts cost of getting Phottix to fix it.

Happy shooting!!
