You’ll need to order the appropriate cap for your body, but after that it’s easy. The pinhole cap even continues to work as a body cap; Photojojo thought to include a clear cover over the hole to keep your sensor clean. Be aware, you’ll need to use a tripod to get any kind of decent looking picture, but that’s not the point, is it? One thing though – $50 is a little steep for a body cap, even if it does have a laser cut hole in it. Why couldn’t you make your own? Props to Photojojo for marketing the idea though.
