In part I am writing this post because unlike my other lens comparison posts lately I end up liking the 50mm lens result instead of the 28-135mm lens. In my other two posts I used a Great Horned Owl and a Bald Eagle as a model, today I use a Red-Tailed Hawk. I ended up not liking the closer up view, in part because it is just not sharp enough. The 50mm lens was a sharper result, but I would crop the image if I was going to edit it. The 28-135mm picture is first. In both pictures I used a tripod and custom white balance. Here they are, what do you think?
