Pentax SMCPFA 100-300mm f/4.7-5.8 SLR Camera Lens

The Pentax SMCP-FA 100-300mm f4.7-f5.8 lens comes in a stylish silver color and works with all Pentax SLR cameras, though the AF system only works with Pentax AF cameras. Its minimum focus range of just 4.9 feet lets you stand close to your subject, while the 100-300mm focal length lets you zoom in for a tight shot or back out for a larger scene. Its small size, just over 5 inches long and only 14.5 ounces, make this versatile lens easy to take with you anywhere.
