Wanna shoot really serious video of the sidewalk on your DSLR, but can't get along with those dicey standard controls? Then maybe VizTools has a solution -- or at least a working prototype it's readying for NAB. The HandiZoom can be operated with only one hand and does motorized zoom with adjustable speed settings, as well as various other primary controls. It hooks up to compatible Canon DSLRs using USB and a rail system, with the aim of making the camera feel more like a traditional news shooter. Check out the video after the break, and then maybe throw down a few more pennies to pair it with one of these.
