U series

Don't miss a moment. Indoor or out.
Suddenly so close you can almost touch it. That's because PENTAX quality and clarity are within reach, at a price that's within reach, too. These compact porro-prism models feature dual-axis, single body design with synchronized eyepiece adjustment. Aspherical lens elements give you edge-to-edge sharpness. Clear images and clearly affordable.
