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.

17 June 2015

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.

  • +

    Long reach, Exceptional image quality on APS-C, Full frame compatible, All-metal barrel, Latest lens technologies, Silent focusing, Weather sealed

  • -

    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.

21 April 2015

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

29 November 2016

My background? I have been shooting with Pentax for..hmmm... since the early 1980s. This is one massive beast! I have it with my K-1 Pentax; total combined weight of 7lbs. I use a monopod to hold this "baby". Construction is built like a Tiger tank..

26 July 2017

Great lens, it has replaced my older Sigma and Tamron lenses with an up to date lens. Every thing that you would expect from a lens of this focal range with all the feature, as with any lens buy a UV filter.

8 July 2017

Very good picture quality. A bit heavy, but I expected it to be.

24 March 2017

It was a gift. It far exceeded its expectations. The fact it could be used under damp situations has proven to be remarkable.

5 March 2017

Excellent but 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

29 September 2016

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.

    Sharpness, AF speed, no CA, build, ergonomics

    Weight, size, pricey

27 August 2016

Very sharp lens from edge to edge. The results are amazing with my K-3. The downside is the weight. This not a lens you should expect to be shooting with handheld-mode very often. It can be done but you will need to kick the iso up so the shutter speed will be in the 1000's range.
