I just picked up Canon's new 40mm f/2.8 STM pancake lens. I'm going to post some test footage later, but couldn't wait to share.
When I started shooting I had an entry level DSLR that at the time (2007) shot video, but it wasn't great and the sound quality was horrible. Now 5 years later, even entry level DSLR cameras shoot HD video and can record incredible sound with an external mic. Because my DSLR couldn't be used for video I had to also bring an HD video camera. I looked kind of silly, I shot stills with my DSLR and built a bracket that would hold my HD video camera on it. I was a one man show so I had to improvise.
