The castle grounds of Castle Schönbrunn in Vienna are like a big feeding dish for squirrels. Because of the amount of people strolling in the beautiful park, the squirrels are not shy at all and sometimes become quite trustful. In the autumn, you can observe them hiding nuts for the coming winter.
That photo is from a Panasonic Lumix TZ-10, the traveller zoom compact camera series from Panasonic that comes with an incredible optical zoom. The latest model, the TZ60/ZS40 [see Amazon] has a 30x optical zoom!
The photo is almost directly out of the camera. I increased definition and sharpness in Apple Aperture [Mac App Store] and used Lossless Photo Squeezer App [OSX App Store] to reduce the file size of the jpeg for this blog.
