It started out innocently enough. My wife wanted to see a presentation at the local historical society but could not attend. I thought "why not ask if I can shoot the presentation on video?". I asked, the speaker and society said yes and we were good to go, or so I thought. It hit me a few minutes later that I could not shoot this with the DSLR as it was too long. The D7000, like most DSLRs, can only shoot about 20 minutes before it needs to cool the sensor and it can get noisy even sooner.
