The Pentax DA 12-24mm F4.0 ED AL (IF) is an ultra-wide to normal zoom designed for cameras with a APS-C (1.5X) sensor. This constant-aperture zoom covers a 12 to 24mm focal-range. It provides the same field of view as a 18-36mm lens on a Full-Frame camera.
This 2X zoom lens focuses down to 30cm from the imaging plane, capturing subject with a maximum 0.12X magnification. 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.
The lens weighs 430g.
This lens is only available for the Pentax K mount. It directly attaches and is fully compatible with all Pentax K mount cameras with APS-C (1.5X) sensors.
