Negative Positive
Title: slow to focus and inconsistent
Review: Attach to a camera and put it on a tripod and photos will for the most part be sharp, although the lens would often hunt for a focus causing a delay in the ability to take the photo. Shooting with a monopod, bean bag or hand held and it took excessively long to focus and more often than not the resulting photo would be out of focus. Not motion blur, but just out of focus. The problem was so bad that I returned the lens.
