Took these little devils on the Grossglockner.
The range was about 60 metres and so on my Nikon Coolpix 8700 I was way into digital zoom to get them. Luckily the little darlings were quite still as the slightest movement (or camera shake) renders maximum range on digital zoom useless i.e. completely blurred.
I always use the full 8mb and the "fine" setting for pics to hopefully get a decent resolution.
