Disappointed with this product. When you attach it to a camera (I have a Diana F Medium) it covers the camera area so you can mount it on a tripod. It also seems like you should be able to press the flash button at the same time as you're recording, and let me tell you, that's next to impossible. I don't think it goes well with the Diana, I hope it goes well with other cameras because it can be such a handy feature.
