Me shooting wildlife (and other stuff) since decades under all conditions:Same price range as the competitors, but without weather sealing and with poorer build quality.
Seems also to me that Canon ends up further and further behind.
A wildlife lens without weather sealing is not a wildlife lens in my opinion.
(And I would have preferred a little extra weight to get internal zoom.)
Some of the lenses were weather sealed, others not. The only lens which stopped working due to internal water was a water sealed L-lens ...
Those long lenses are super easy to protect if protection is needed during shooting.
