No, that is wrong. You have a 140-600 lens, period. When you put it on your camera, it looks like a 70-300 lens would look on a 35mm camera. But that's just for convenience.

I think you've got it backwards. What he has is a lens with a focal length of 70-300mm, but on the 2X crop factor body, it has the same field of view that a 140-600mm lens would have on a 35mm camera.

Definitely not right. A better way of saying it is the 600mm focal length lens on your camera has the same angle of view as a 300mm focal length lens on a 35mm camera.

Again, just turn it around: a 300mm focal length on his Olympus has the same angle of view as a 600mm lens on a 35mm camera.
