A day at the zoo with the new Sigma 150-600mm Contemporary

I bought the new Sigma 150-600mm Contemporary lens a few month ago for a film job but since then never got the chance to test it as a photo lens until last weekend. A day trip to the Zoo Pairi Daiza was the perfect opportunity to try this lens out. 
I'm quite please with this lens. Sharp, silent, no much distortion and fairly lightweight compared to the Sport version. Talking about Sport, I tried to focus on flying eagles and couldn't nail a single one. I'm guessing that's where the Sport model would shine.
