I think the concept is pretty self explanatory. You're looking for a solid Video head with smooth movements for video, but you're also shooting stills and need the Vertical (portrait) position. Hybrid cameras require a Hybrid stabilizer. This new Manfrotto MH055M8-Q5 a.k.a 'Q5' Photo-Movie tripod head gives you the best of both worlds. It's a more professional video head designed to support a bit of weight, so it's not something for the average light weight point and shoot photo/video camera. But if you want to save on the amount of gear you travel with and still have professional results for both Photography and Cinema, it's something to consider (if you can get over the odd look).
