p.1 #1 · 3D Rig Using Two NEX-5s


I'm part of a project covering the end of the Space Shuttle Era. We're a small group of photographers with incredible behind the scenes access. We're capturing the action with rich technologies and wanted to do 3D images as part of it. We've tried a few approaches, but we're currently using the Sony NEX-5. Even though Sony has a 3D effect built into the camera, it does not capture 2 images at the same moment in time. So we're using TWO Sony NEX-5s that fire synchronously. Problem is to get the spacing between the cameras correct to have the proper 3D effect and not give the viewer a headache. So one camera is inverted so we can get the lenses close enough, and we are using Nikon 20mm lenses with Nikon to Sony E adapters. The cameras are fired though IR. Bob Fisher, our project's "Widget Guy", created the circuit, and the San Diego Air & Space Museum's restoration shop machined the bracket. Bob then put it all together.

Here's a couple shots of our rig as it currently exists:

The small size and weight makes working with two NEX-5's a breeze and . . . there's no shutter lag. The inverted camera also rotates the image file to right side up . . . that was a unexpected but pleasant surprise.

Here are some links to learn more about our project:

And here are a few of the resulting 3D images (you'll need a pair of anaglyph 3D glasses):

Cool! Are those nikons optically identical?

Pat,

Welcome to FM. I really look forward to seeing the results. I also look forward to getting a pair of anaglyph 3D glasses.

Very few of us get a chance to document something so important, and so interesting. Your contributions will outlast all of us that are currently reading this thread.

Do you know stanj ? http://www.phototrek.org/Travel/STS-93/exposure.html

Cheers, Jim

That's awesome, Pat, in the truest sense of the word. And a really cool application of the NEX.

So I know zilch about 3D filmmaking, but I'm curious about why one camera is mounted a bit behind the other. Is that typical for 3D shooting?

Freak--looks like two different versions of the same lens, but the chips are in the same plane.

Very cool stuff, Pat! Thanks for sharing.
