More wildlife from Soria. During my visit to Cañón Río Lobos I had the chance to spot some griffon vultures overflying us. Even though they were flying low, the distance was considerable and required use of telephoto. In this case, I had my old 70-300mm, but a 400 would have come fancier.
Wildlife photography is really challenging. Besides the general high-speed movement of the vultures, harsh light conditions and the dusty, hazy air resulted in a bit of softness and some extreme blue fringing at the tips of the feathers. If I ever decide to go further down the road of nature/wildlife photography, I would probably need to get a sharper telephoto lens, but in the meantime I will stay on budget and keep the old one.
