The intent was to demonstrate the variance in Field of View (FoV) between a Nikon APS-C (DX) sensor and a Full Frame (FX) sensor rather than the misunderstood "extra reach" a cropped camera will give. A 50mm lens is a 50mm lens regardless of the sensor size. Look beyond the monkey. I took two common focal length prime lenses, 35mm and 50mm. The side-by-side images demonstrate this fairly well IMO. You'll also notice further down that a 35mm lens on a cropped body will yield a very close approximation that a 50mm lens will produce on a full framed body. Even further down, the 100% crops shows how the FF sensor renders a smoother bokeh, again, IMO. Plus, the tequila was at a perfect temperature and tasting mighty fine that day.
