And judging from the magnification increase at min focus distance the focus breathing "issue" has been seen to.
The lens will focus up to 1.1m at all zoom settings, so the largest magnification factor should be achieved at the longest 200mm setting.
Based on the magification factor of x0.21 and the focus distance of 1.1m (1,100mm), the focal length at this setting is 157.776mm (if the calculation is correct). The lens definitely uses focal length shortening method. I'm not sure if that would lead to be breathing, though.
