Re: Where does the 70% number come from?

In what way are the laws of physics misleading?

It's like saying that uprezzing an image by 50% degrades the quality by 50%.

It does in exactly the way expected. The resolution per millimeter declines by 50%.

I think this is more realistic: http://photographylife.com/image-degradation-with-nikon-teleconverters

As I said, the fact that the sensor resolution stays constant and image resolution is a function of both lens and sensor resolution may make the problem less significant.

Note however, that this is for the case where we are comparing a lens to itself, with and without TC. When we are comparing a lens with 1.4x TC with another lens without TC, the lens with TC has to be 1.4 times better in order to match the lens without.
