Pentax 16-45mm F/4 SMC DA ED AL K Mount Autofocus Lens For APS-C Sensor DSLRS {67} Description


Announced December 2003, the SMC DA 16-45mm f/4 ED AL lens was Pentax's first lens specific for DSLRs with APS-C size sensors with a reduced image circle in comparison to their 35mm lenses during that time. The SMC DA 16-45mm f/4 ED AL also maintains constant maximum aperture throughout the zoom range. Its focal length is equivalent to 24-67mm focal length in a 35mm format. The SMC DA 16-45mm f/4 ED AL concerts Extra-low dispersion glass element and two aspherical elements promoting top quality imaging production. The lens offers Pentax's Quick-shift focus system ensuring swift shifting from autofocus to manual focus using the focus ring. 
****Not recommended for 35mm film or full frame DSLRs.

The Pentax smc P-DA 16-45mm F4.0 ED/AL is recommended for use with digital cameras. It features a 3x zoom ratio with focal lengths covering ultra-wide angle to normal ranges, incorporates a high-refraction extra low dispersion (ED) glass element to produce a high-resolution, high-contrast image with true-to-life color rendition, and aspherical lens elements to help transmit the light more efficiently through the lens to the focal plane. The smc P-DA 16-45mm F4.0 ED/AL is well-suited for advanced amateurs and professionals.
