The Pentax SMC DA 18-135mm f/3.5-5.6 ED AL (IF) DC WR Lens is a premium telephoto zoom lens specifically engineered for Pentax digital SLR cameras. It provides a focal length equivalent to 27.5 to 207mm in 35mm format, making it suitable for a wide range of telephoto uses, such as portrait photography, sports, and landscape imagery.
The image circle of DA-series lenses is meticulously crafted to align with the 23.5mm x 15.7mm dimensions of the CCD sensor found in Pentax digital SLRs, thereby enhancing overall camera performance. This thoughtful design also results in a significant reduction in size, weight, and manufacturing costs when compared to similar 35mm-format lenses.
Pentax DA (DA-Star) zoom lenses feature the SDM System, which ensures a smoother and quieter autofocus experience through the integration of a built-in supersonic motor. Consistent with all Pentax lenses, this model is treated with smc coating to maximize light transmission, achieve sharp image definition, and produce high-contrast photographs.
Furthermore, the front surface of the lens is enhanced with SP (Super Protective) coating, composed of a specialized fluoride compound, applied via a unique evaporation technique. This results in exceptional resistance to water and oil, facilitating easier cleaning in the event of smudges from fingerprints or cosmetics.
