We've got the biggest iMac till date on the show -- the stunning 27-inch beast with a jawdropping 5K Retina display. We unbox this beauty and also give you our review. Panasonic has launched the new Lumix S series and we've got the Lumix S1 and the Lumix S1R, two full-frame, mirrorless cameras, on the show. We will show you how these cameras can transform your photography experience!
