I’ve been working on this project for a while & now seem to be getting somewhere, the idea was to keep the already versatile NA-EM5 & 12-50 set up as small and light as possible.

Made of two sheets of vacuum formed HIPS bonded together with an acrylic diffuser at the front, the inside is white to reflect as much light forward as possible using the standard Olympus flash.

Here’s a couple of shots taken with this set up:

I would be interested in any thoughts you have on this method of lighting.

I do not know about the lighting, but the vacuum formed part looks nice.

:good:

I saw this (in the flesh) the other day - and it does look well made. And from your photos it is clearly working.

 

The main limitation is that it restricts you to just one type of lighting and one type of shot (close macro). I can't see it giving useful lighting at the wide angle end of the 12-50mm.

Thank you for your comments on the build, the vacuum forming has been an interesting project in itself and I’m now looking forward to getting lots of use from it.

 

Alex, your right about the wide angle end, It’s a bit like a fixed ring flash or snoot in that respect and could also be said for using dedicated macro lenses however switching the flash off does give the ability to use the wide angle where natural light is available, in my case that’s often the beginning and end of the dive.

 

Cheers, Gary.
