With a visitor staying with us, and birthdays to celebrate, we took a trip up to
Colchester Zoo last week. Knowing that it would be a long day of walking about, I decided just to take my K10D and the Sigma 105mm, which would allow me to take macro shots if needs be, but also allow for plenty of cropping to frame the shots as I wanted, as this is an incredibly sharp combination.
Here are a few shots from the day.

Well worth a visit!
