Hands-on review: Canon EOS 5DS

The EOS 5DS is actually based on the existing EOS 5D Mark III. In fact, if it weren't for the logos on the new camera, you might find it pretty hard to tell them apart.But that's OK, because the 5D Mark III has proved itself an extremely capable, versatile and robust camera for professional stills and video photography, but at a price that won't break the bank. Well, not quite.It's interesting that Canon chose this product line for its new 50-megapixel sensor rather than the top-of-the-range EOS
