All these pictures where taken with my 50mm (didn't feel like taking my heavy 24-70 with me, and I promished the miss that I spend more time with her than with miss d700
) and are a mix between behind glass, behind bars, in the free.
For the animals behind bars I didn't stop down, this to keep the bars out of focus. But with my 50mm 1.4g quite a lot of purple fringing can occur in strong light, and it was a very bright day.
behind bars,........................ just kidding
