My DIY Ring Flash Adapter

I think I've wanted to make a ring flash adapter from the first time I saw one. The results were awesome and it seemed like a good challenge.


And then I thought it would be easier to just buy one...


But after searching the Interweb for a while, I found that all the good ones were too impractical and/or too expensive, and the cheaper ones were just crap. Some weren't even a ring!


So I HAD to make one!

It would have to:

- be cheap (preferably free),

- be a ring (duh!),

- be very light,

- have even light distribution,

- NOT look like crap!


Took some measurements from my camera and flash, made a model in Google SketchUp, "unfolded" it and printed the result. Made a cardboard prototype in no time, a few adjustments, and it was ready.

The final material would have to be some kind of plastic sheet, which I didn't have and didn't want to buy. So the prototype sat in the back of a closet for 2 years...


Finally, I was able to "recycle" all the ingredients. Some black plastic binders that were going to the garbage at my sister's work, a translucent one I already had, a plastic mirror and some aluminium tape.


After a few days of cutting, scoring, notching and gluing, the results Were way better than I could have expected. The light distribution is near perfect. It weights around 140g and it's held in place just by friction. I can handle the camera any way I want and it just won't fall. And most of all, it was practically free!

As for the looks, I am very pleased but... you tell me!


The only downside to this version is that it's made specifically for one camera / lens combo. In my case, a Nikon D90 and a Nissin Di866. So when I upgrade either one of them, I'll have to build a new adapter. So...?!


If you're interested in making your own, I uploaded the SketchUp file here. You'll have to measure your own camera and flash, and make the necessary adjustments. In the file there is also an example of how I managed to glue the parts.
