I am loving my Nikkor 60 mm lens for taking extreme close-ups. My son sent me a link today to an article in the New York Times that featured a woman who is an exceptional photographer and very inspiring to me with her artistic photographs of flowers in extreme close-up. They're breathtaking. Thanks, Matt.
