Make DSLR buttons more tactile

Here's a quick photo of my sugru-enhanced buttons. DSLR cameras aren't meant to be used to shoot video, but it has become a great way to shoot incredible quality footage in HD with light-weight equipment. When I've been filming lately and need to change the ISO in a hurry, instead of pulling back from the view finder and possibly losing focus or framing, I just feel for the sugru button. This way I can change the settings quickly without losing my camera subject. A tiny bit of sugru goes a long way. Paul, London.
