Mark is excited about the new Nikon full frame mirrorless camera. Leo says that Canon is likely going to announce one too, and it could be that the DSLR is on its way out. Mirrorless cameras are smaller and lighter. But it comes at a cost, as it will lose the optical viewfinder in favor of an electronic viewfinder. The sensor is also close to the lens and that means simpler optics. Photokina is coming September 26th, and we'll likely see both the Nikon and Canon full frame mirrorless cameras.
