Och, yes. A flash was out of the question, firstly because the X-pro doesn't have one and more importantly because the animals are behind glass. The reflections would kill the photo...

Och, and the Antwerp Zoo opens @10h00, but those with a pass (which I have) can enter as early as 9 o'clock... I was a little earlier but looking in a pleading way did the trick - they let me in! Apart from the zoo keepers there was no one. Really magical!
