I received inquiries to make a sound blimp for a film-still photographer. With the client’s sponsor, this time I can try some better materials. Note that I glued a 4″ PVC tube-lid onto the box, allowing us to screw mount the lens tube. Moreover, the twist-able part of the lens tube will be in contact with the lens, which give us the possibility to zoom a lens without taking the camera out of the box, adjust the zoom range and put it back again.
The blimp is made for a 5D mark II. So a 1150 Pelican case would suffice (if you want to include the battery pack, you will need a 1200 case). I employed a Yongnao wireless trigger to act as shutter, which produce less clicking noise than its wired cousin. Averagely speaking, Asians have smaller pair of hands, so the shutter button is placed at the side. I think it gives better grip for average hand size than placed in front.
I ditched the original sponge, and returned to some denser cushion sponge for the interior. It might not be so nice looking with my hand-cut outlines, but it gives better performance in sound proofing for its higher density and less remaining space. Without much space for shutter sound to resonate, sound proofing ability is thus improved.

Putting a rubber band around the zoom-ring, so it is in touch with the foam inside the lens tube. When the tube is turned, so the zoom-ring.
Demo video of zooming. Sorry for the crude quality, hope you can feel my eagerness to show the world what I have made. The zooming may be a bit clumsy, but it is more convenient than taking the camera out of the box, adjust the zoom range and put it back again. I am still trying to figure out a way to zoom lens like 24-70mm and 24-105mm, which length changes while you zoom.
Inquiries are welcome. If you want to order a sound blimp from me, please email me at info@workandworkshop.com. Specify your camera and lens model. Once the price is agreed, you will be asked to provide a 1:1 scanned image of you camera (front and back) and lens (front and side), for the purpose of accurate positioning.
