It also features the PENTAX-original Quick-Shift Focus System for instant switching to manual-focus operation and PENTAX-original SP (Super Protect) coating to repel dust, water and grease. A new SDM system has been incorporated for smoother, quieter autofocusing operation using a built-in supersonic motor.
