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.

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.

This is the first true successor to the FA* zooms with excellent rendition, full-frame sharpness, and superb Pentax coatings plus the welcome addition of WR. It is big and heavy, but no more so than other lenses of this range and quality. Great for wildlife.

I was pretty happy with my Sigma 120-400 as a good value (bought used) overall, but wondered if I could get better focus accuracy and richer color with the Pentax. Typically, the Sigma's color rendition was on the cool side, and it only focused passably in terms of speed and accuracy (~50% hit rate,...

this is a heavy lens not for hiking but perfect so far for what it is intended for. so far i have used it on a tripod mounted on a K3 with the converter which gives me more reach and have got some nice shots of wildlife so far. when it gets warmer i will use a tripod and a blind.

This is a pro-quality, all weather lens. Razor sharp, even wide open. Good contrast, low chromatic aberration. It focuses fairly close – 2 m, and the autofocus is smooth, fast, and silent. It’s also very accurate. I use the lens mostly for birds and other wildlife.
