When talking about the 1.6x multiplier on the focal length. Isn't it a little mis-leading to say that, "Your inexpensive 100 - 300mm tele is now a whopping 160 - 480mm monster lens..." It is my understanding that the field of view is cropped so your lens still has the same magnification and depth of field of the lens you are using. So a 300mm lens still has the magnification of a 300mm lens not a 480mm lens, the image is just cropped like you were using a 480mm lens. You are not actually bringing the object closer. Someone please correct me if I am wrong.
