The Pentax HD D FA 150-450mm F4.5-5.6 ED DC AW is a solidly-built telezoom lens, but it's heavier and pricier than others in its class.

Sharp through most of range. Top-end build. Weather-sealed design. Focus limiter function. Includes tripod collar.

Slow focus. Heavy. Very expensive. On the soft side at 450mm. Some distortion.
The HD Pentax-D FA 150-450mm has proven to be nothing short of a top-shelf lens boasting professional features and delivering superb image quality on APS-C bodies. It is capable of producing sharp, clear, and aberration-free images— the dream of any telephoto lens owner.

Poor ergonomics, heavy, Soft corners and low contrast wide-open (450mm), Slower to focus than competing systems, 1-year warranty (US / Australia)
This 3x super-telephoto zoom lens covers an interesting zoom range which fills a long established gap in the Pentax line-up, as telephoto zoom lenses have been thin on the ground, with many Pentax camera owners relying on offering from third-party lens manufacturers.
Pentax camera owners have been crying out for a decent telephoto zoom option, similar to those offered by other camera manufacturers, for an age and finally their prayers have been answered with this lens.

Very good sharpness, Weather and dust resistant construction, Good build quality, Silent focusing, Full time manual focus override, Low falloff and distortion

Zoom creeps as lens is tilted and no lock only functions at 150mm, High CA levels at 450mm
Pricey lens but once you stopped sobbing over the hole it made in your wallet and start using it, you will quickly forget that. Very very good IQ on all focal lengths straight from wide open. Closing down 2-3 steps makes it a little better but mosty just expands the DOF.

A little heavy
Got a great bargain from SRS in the Black Friday deal - GBP1200 (including tax!) Been lusting after this lens since I first saw it in Feb 2015. Only just had the chance to put it through a quick try since getting it, but so far very impressed with it.

This lens is simply excellent in terms of sharpness, contrast, and overall rendition. Comparing it with other two tele-lenses which I own, it is slightly better, at 300mm, of the FA* star 300mm f4.5, and at 450mm it delivers more details than the K 500mm f4.5.

Very sharp also wide open, fast autofocus, very good construction

The plastic hood is too light and looks frail
I purchased this lens as a replacement for my F-300mm because I was looking for more reach, faster AF and WR. The image quality is very good, especially for a zoom. Not quite on par with the F-300mm but very close. And definitely sharper and faster than the Sigma 150-500 I'd been borrowing.
