Essential HD Video Accessories for DSLRs from Adorama Learning Center: "Convergence is a marvelous thing. The ability to combine the elements of high-tech electronics and software in unprecedented new ways his resulted in such marvels as the iPhone, the Blackberry, 8-megapixel cell phones, and yes, digital SLRs that can shoot HD movies of breathtaking quality. When I asked a PhD physicist and software developer why Nikon, Canon and now Panasonic decided to include HD movie capability in their latest DSLRs, he responded laconically, “Because they can.” Yes, you can shoot HD movies with your HD-enabled DSLR alone without using any accessories whatsoever other than a lens and a high-capacity memory card, but if your aim is to produce professional looking movies and movie clips, the following accessories will certainly help."
