Thanks Amin. Based on these and the other photos I took this past weekend, it's quickly becoming one of my favourite lenses. I've mainly used it for macro work so far and next weekend I'm going to look for a sporting event to try it out on. At this point I haven't used it for any portraits, but will need to give it a try. That's a great photo of your dad.Terrific set of images, Walt. Looks like the new lens suits you well!
