Tony Northrup, is the author of 2012-2013 #1 photography book, "Stunning Digital Photography" (buy here) and famous for his rigorous reviews about photography equipment.
Tony explains this is the real aperture of his Panasonic f 2.8 lens

  This video can revolutionize our way of thinking about our cameras, lenses and manufacturers.

 Tony explains that only Canon, Nikon and Fuji are honest with his specifications with crop sensor cameras. It is a long video, but you must watch it to understand how to get similar results to a full frame sensor camera with a small sensor camera. Could be this true?
