This is a great lens! I have taken up photography again. In my film days I used Pentax Cameras and lens to do sports photography. I now enjoy nature photography so I wanted a telephoto lens so I could get in close to take pictures of insects and flower blooms. The Pentax HD Pentax-FA 77mm f/1.8 Limited Lens is great for this type of photography.
