I interrupt your regularly scheduled flower and insect pictures for another picture of the dish.
This was taken with the 50mm f1.8 prime -- I can't really quantify it, but it really out performs the 17-35mm Tamron. Definitely something in the sharpness and color.
The funny thing about the cows on the other side of the fence: there's a gate (open) and no fence leading up to the dish. So, theoretically, if a cow could cross a metal bridge made of bars, they could walk the dish with us. Or, say, if a cow went nuts, some poor hiker could get mauled.
