This is a great lens in almost all respects, with auto-focus being its major issue. Ninety percent of the time it focuses fast enough and produces excellent results. I may even go higher and say 95% of the time. But in some circumstances it is hit or miss, such as being out on the water in low contrast situations trying to capture whales and other wildlife that may spring into view suddenly and you only have moments to frame the shot and shoot. I have adapted my technique to compensate for this as much as possible. In clear conditions, prefocusing on the area where you anticipate a whale may surface, or switching to manual when the light is low or the environment is misty/foggy and inherently low contrast.
Don't get me wrong, even though it has a little heft I don't have any trouble in carrying it around on the camera for a days shooting and love the results it gives. It is sharp, low CA and nice bokeh for a zoom. I wouldn't part with it for the world. |
