Canon uses electrical tape to fix $3600 camera body's light-leak

I hope it's better than just electrical tape. Some of the cheap stuff uses crappy rubber adhesive that dries to powder after a while. Wouldn't that be nice inside the camera? Likely, they're using an acrylic adhesive tape. Maybe. http://www.dpreview.com/news/2012/05...d-Roger-Cicala And your point is? Film based cameras used a neoprene foam light trap. -- Mike |

Methinks his point is that neoprene foam isn't electrical tape. Mike's point is likely that the material need not be exotic, complex or expensive. Merely effective and easy to retrofit without changing over time, humidity and temperature. For that matter, it doesn't necessarily need an adhesive if the assembly locks it in place. -- "A person with a new idea is a crank until the idea succeeds." -Samuel Clemens. |

Hey, it looked like cheap plastic electrical tape! Everyone knows that on expensive quality cameras it's absolutely essential to use stuff that looks expensive. Some manufacturing tapes are extremely expensive. The most expensive tapes are teflon re-inforced with a woven material, like fiberglas or carbon fiber. Kapton tapes which are used in electronics cost a lot too. You can also get pure metals with adhesive backing for shielding. The two primary higher performance adhesives are acrylic and silicone-based along with some very strong partially-curing epoxies. Nikon has used kaptons to hold things like ferrite noise - supressing rings in-place in cameras. |
