When returning from a shoot, it can be a bit of hassle to match up the audio tracks from the DSLR and our Zoom recorder. Luckily, planet5D posted a hardware solution. Lockit Buddy is a device that sits atop your DSLR and syncs timecode between your audio devices and your Canon T2i, 5D mkII, 7D or 60D. They’re on sale now for 94.99 pounds (about a 150 dollars.)
