<p>Also, in some earlier comment in this thread I saw that Shun compared the focal length of the third party 150-600 lenses to the Nikkor. According to some sources the third party lenses exhibit quite a lot of focus breathing and at closer distances they are not even near 600 mm. Can anyone with a third party lens verify this?</p>
