Pairing a versatile zoom range with a fast, constant f/2.8 maximum aperture, the Pentax D FA* 70-200mm f/2.8 Lensis a telephoto zoom designed for Pentax D FA* 70-200mm f/2.8 LensK-mount DSLRs. Offering a 105-300mm-equivalent focal length range with APS-C cameras, this lens is particularly well-suited to sports, landscape, and wildlife uses, especially when working in trying light conditions. Extra-low dispersion glass elements have been incorporated within the optical design to minimize chromatic aberrations and distortions, as well as produce a high degree of sharpness from edge-to-edge. HD and Aero Bright coatings have also been applied to lens elements to reduce reflections and flare and a Super Protect coating also helps to shield the front and rear elements from dust, water, and oils. Further enabling its use in difficult conditions, this 70-200mm f/2.8 also features a weather-resistant construction with 13 separate seals to block moisture and dust from entering the lens.

In regard to focusing, a DC autofocus motor realizes fast and quiet performance and is accentuated by the Quick-Shift Focus System for changing between AF and MF control by simply turning the focusing ring. Additionally, a removable, rotating tripod collar is included with the lens for more even balance when shooting atop a tripod.

One of the most versatile zoom ranges, this 70-200mm lens provides a 105-300mm equivalent focal length range when used with Pentax APS-C DSLRs.

A constant f/2.8 maximum aperture delivers consistent performance throughout the zoom range and is particularly beneficial to creating shallow depth of field imagery.

Extra-low dispersion glass elements are incorporated within the optical design to minimize chromatic aberrations throughout the zoom range and produce high image clarity with edge-to-edge sharpness.

High Definition (HD) and Aero Bright coatings have been applied to lens elements to reduce surface reflections, flare, and ghosting in order to deliver greater contrast and color fidelity. Additionally, a Super Protect (SP) coating also helps to protect the surface of exposed elements from fingerprints, water, dust, and oils and also makes the front and rear elements easier to clean.

A Direct Current (DC) autofocus motor benefits from an internal focusing design and delivers fast, smooth, and quiet focusing performance.

The Quick-Shift Focus System allows you to first use autofocus to acquire general focus on a subject, then instantly refine your focus position manually without the need for an AF/MF selector.

A focus range limiter allows you to constrain the lens' focus range between different sets of distances for faster performance and greater responsiveness.

The weather-resistant construction utilizes 13 distinct seals to prevent moisture or dust from entering the lens.

A removable, rotating tripod collar is included with the lens for better balance when shooting atop a tripod.

Q: 5. I really love my K3 and do pet photography with it. I need a good zoom that's quick on AF. The Pentax smc PENTAX-DA* 50-135mm f/2.8 ED (IF) SDM Lens just doesn't autofocus quickly enough.The web page for this new Pentax 70-200 says The Quick-Shift Focus System allows you to first use autofocus to acquire general focus on a subject, then instantly refine your focus position manually without the need for an AF/MF selector. Is this Pentax again not being able to pinpoint focus the way Canon, Nikon, Tamron and Sigma seem capable of, or do we have a genuine capability here for instant lock on moving objects equivalent to say the Tamron 70-200?

A: The new 70-200 is a fast lens but so is the 50-135mm lens. Both are f/2.8 which helps the focus speed. But the cameras focus system does have a very large part to how fast and accurate it can focus.Just to compare the K-3 has 27 Phase Detection autofocus points and the Nikon D7200 has 51 Phase Detection points and 15 cross-type focus points. So in most cases the Nikon Model will focus faster and more accurate.

Q: 6. Under listed specs, only ASP-C is the compatible format. I thought FA lenses were native 35mm format. Is the information posted re compatibility accurate?

A: Yes, the Pentax HD PENTAX D FA* 70-200mm f/2.8 ED DC AW Lens would be compatible for use with full-frame cameras. As the lens was released in 2015 and Pentax's full-frame camera was not announced until 2016 (all previous DSLR cameras being APS-C cameras), our website did not indicate which Pentax lenses were full-frame compatible. It is listed under the Product Highlights on the lens' webpage, and our website will be updated soon listing which Pentax K-mount lenses would also offer full-frame coverage.

Q: 7. What focal length multiplier is compatible with this lens on the K-1?
