Pentax DA 16-45mm F4 ED AL Lens
The Pentax DA 16-45mm F4 ED AL is a wide to normal zoom designed for cameras with a APS-C (1.5X) sensor. This constant-aperture zoom covers a 16mm to 45mm focal-range. It provides the same field of view as a 24-67.5mm lens on a Full-Frame camera.
This zoom can focus down to 28cm from the imaging plane which gives it a maximum magnification of 0.26X. The lens offers a Quick-Shift AF system which lets the user simply rotate the focus-ring to focus manually. While this lens is capable of AF, it does not have a built-in focus motor. It can only focus with a compatible camera body which features a mechanical AF-coupling.
This lens is only available for Pentax K. Follow this link for all current compatible digital cameras: Pentax K mount cameras with APS-C (1.5X) sensors.
