Designer and maker George Moua has built a bespoke 3D-printed 3D stereoscopic 'wiggle lens' for full-frame Sony E-mount cameras and APS-C Fujifilm X mount cameras. The 3D-printed lens allows compatible cameras to shoot stereoscopic wiggle photography. Essentially, by combining multiple frames shot with the lens, you can create a motion picture that appears to be 3D.
Moua's stereoscopic wiggle lens incorporates a trio of 30mm lens to project three images with slightly different perspectives across the image sensor. The wiggle lens creates a parallax shift in between each frame, such that when you combine them into an animated sequence, there's a visual sense of depth in the animated frame.

The full-frame version, seen in Moua's video below, extends as far as possible into the lens mount without interfering with the shutter or IBIS mechanisms. However, the baffles can't touch the image sensor, so there is some slight light leakage in between each frame. This is easily corrected in post, as we'll see in a second video. The lens also uses a breech-lock mounting system rather than a standard bayonet lens mount, which means that the lens is attached to the camera using a rotating ring that tightens the lens to the body. Moua has also crafted a bayonet mount version, although it offers poorer performance.
Creating a wigglegram is not as simple as just capturing the image. Moua has created a video showing his workflow to create wigglegrams using Adobe Lightroom and Photoshop. Moua shoots with a Sony A7, so it's a 3:2 aspect ratio. Using a 1:2 crop ratio, Moua crops three frames from a single image. He exports each crop as a .DNG file and then imports them back into Lightroom. Once the individual frames are in Lightroom, he edits them such that they have the same appearance, as there is sometimes variation in brightness, contrast and color across the three frames. When the images are matched, he opens them as layers in Photoshop. To see how Moua creates a wigglegram in Photoshop, check out the tutorial below.
Unfortunately, preorders for the full-frame Sony E-mount, APS-C E-mount and APS-C Fujifilm X mount stereoscopic wiggle lenses have sold out. However, Moua intends to make STL files available for sale once he has fulfilled his preorders. The lenses sold for $80 for the full-frame version and $70 for the APS-C versions. Moua will be using his profits to purchase a Canon EOS RP to finish work on a Canon full-frame version of his stereoscopic wiggle lens. He is going to work on a Nikon version down the road as well.
