My new diffuser

So I spent £30 and got myself a new dome diffuser. It arrived today and below is the first shot I took with it - of my son. Please excuse how he looks - he is home from uni



As far as I am concerned, I am quite happy with the diffuser except for one small niggle. The dome appears to be quite heavy so the flash has become top heavy and tilting it forward even a tiny bit makes it to collapse (I hope I have made it clear - I have set the flash pointing straight up). Are there any DIY fixes?
Cheers

What diffuser is it?

As for falling, what flash is it mounted on?

Thanks Dan. Below is a shot of the setup - the dome diffuser set atop a Metz 58 flash. With the flash extended straight up, the top becomes very heavy and tilting it a bit will collapse the flash at the hinge.

Hmm, I have one of those and it's not the lightest diffuser in the world. However my AF280T holds the weight at any angle I choose.

Might be worth a word with the supplier of the flash to check whether the tilt action on yours is looser than it ought to be?

Thanks Steve.
I'll have a chat with them next week.

Weight will be a problem but Having used similar ones in the past I didn't find it too bad.

Where did you get it and which size as I need 2 for my Metz 58s.

Thanks Dan.
I got it from Premier ink and Photographic. Size 3.

Can I ask where you bought the diffuser? Been trying to find one to fit my Metz 48 AF.

Woops I somehow missed the answer in the previous post

How does it compare against the collapsible version of the Gary Fong LightSphere?

I've been considering a lightSphere for a while...

Dave, I have never used a dome diffuser before so can't really comment. This one seems to work fine though.

Microglobe do a good range of diffusers at good prices
If you have the 540fgz the Nikon SB900 one fits
The Microglobe MQ-I Chrome Dome Lightsphere Cloud Model is a great addition.

umn.. I go to the dollar store buy a little rectangular plastic water bottle and cut the top off and squeeze it on... you'd be surprised how well that works..

Won't the water damage the flash!

I've mentioned it before, but I've had great success with the design here:

Costs a couple of quid in total. If you are feeling really adventurous, then buy some coloured foam to make a version that'll give a bit of extra colour to a scene
