confirmed prices for Nikon 19f4 PCE and 70-200f2.8 VR
#68
;Any lens which does not change focal length through the focus range does show focus breathing, Wim. They narrow the FOV.

There are two "types" of focal breathing: The lens can narrow the FOV and the lens can winden the FOV. In my above image example, you see two IF lenses. One widens, one narrows.

 

To calculate FL correctly, one needs to know the nodal points. How did you figure those out?
