In-body Shake Reduction

Because shake reduction is built-in to the camera body, this means that any lens compatible with the K-Series cameras will benefit from image stabilization.

Dustproof and Weather Resistant

Developed as an All Weather model (AW), this lens features a dependable dust proof and weather resistant structure with eight seals to prevent water and dust entering the inside the lens. Couple with a weather resistant PENTAX DSLR, it forms a durable and reliable imaging system that will perform superbly in demanding outdoor weather conditions.

Bright and Clear Images

This lens has been treated with Aero Bright Coating II - a lens coating nanotechnology delivering a super low refractive film. This is combined with the high grade, multi layer HD coating which reduces reflection in the visible light spectrum 50% more than traditional lens coatings. This reduces flaring and ghosting to a minimum even when the subject is back lit.

Beautiful Bokeh

Nine blade round diaphragm to produce natural bokeh at up to F2.8, while minimsing the effect of light streaking. A minimum focusing distance of 40cm which enhances the effects that can be achieved with the bokeh. The KAF4 mount features an electromagnetic diaphragm control which allows for high precision exposure control during video recording. Super Protect Coating (SP) helps repel dust and grease.

pentax k-mount since 1975

The PENTAX K-Mount has been used in PENTAX SLR's since 1975. This means that you can use any K-Mount lens with our current range of DSLR's. The functionality will vary as technology has moved on since then but provides the perfect opportunity to try out your old lenses.

    Customers are satisfied with the auto focus of the lens. They mention that it is very good, fast, and quiet. The focus limiter keeps AF snappy, and the lens acquires precise focus before the pressure signal fires from the camera. The focusing ring is smooth and silent. The range limiter is a nice feature, but it almost seems redundant with this lens' focus. The lens is sharp at both ends and the focus throw is beautifully balanced.

    Customers appreciate the value of the lens. They say it's a good budget lens for outdoor use. They also say the IQ, dof control, and bokeh are worth the weight and cost. Customers also say that the images are well worth the extra dollars.

They also like the picture quality and slick operation. The lens works flawlessly on their cameras and is compatible with Nisi filter systems. It is great for wide-angle work on landscapes and buildings.

    "...I have used it both on my K1 and K3 bodies and the results are very consistent...." Read more

    16 customers mention16 positive0 negative

    Customers are satisfied with the noise of the camera lens. They mention that the AF motor is silent and has no trouble locking onto the subject. The motor makes much less sound than most lens based image stabilizers.

    "...The DC motor is almost silent, much more than similar arrangements in older non ring drive lenses with competitors, and fast and decisive in focus..." Read more

    "...Minimum focusing distance is 1.2m. DC autofocus is quiet and usually accurate. Abberations are unusually well controlled...." Read more

    "...Needless to say it isn't. It barely makes a sound focusing and does it in a snap from the closest to furthest focal points...." Read more

    "...Yes, it's that fast. And it's silent...." Read more

    Customers are mixed about the weight of the camera lens. Some mention that it's small and lightweight, while others say that it is quite heavy.

    Many years ago I used to shoot with a 50 mm on a film camera. I shot for Mexico the US all over on a 50 mm lens. I have several 50 mm but none like this one. This lens is really nice only thing is it is heavy with glass, but I don’t mind that all of these years from the 60s to now it’s about time. They came up with a nice lens like this I took it out and I tried it and it sure does take some nice pictures of flowers.

    5.0 out of 5 stars This is the one. Boom, baby.
    Reviewed in the United States on September 24, 2018
    I waited a lifetime for a really killer lens for my Pentax. First with my MX (film camera, quite some time ago) I got the 35-70 f2.8 SMCP, great lens, difficult time to do photography for me. Decades later I retired, got a K-1 (Finally a full frame digital Pentax; YAY!) and then when I fell into some money, I purchased this 150-450, the big one, same cost as the body. Worth every flippin' penny. I've been shooting Hummingbirds at my feeders (No, no, put away the Browning) and just wasn't getting the results I was after. (80-320mm Pentax brand lens) Printed at 13x19, they were good... I guess... Then this thing got delivered. Turn the page! Contrast! Sharpness! Vivid, OMG images! Heavy! (ok, that's not so great... but it's what it takes, I'm ok with it. Camera and lens weigh the same as an M16.)
    The auto focus is fast and silent, too. It's still hard to get good images of hummingbirds, don't get me wrong; their colors are reflective and totally dependent on perfect lighting and they move like little feathered bullets. With my killer lens I can get a little distance and keep 'em large on the frame, and when I do my job the images are wonderful!

    It's BIG and HEAVY! Read the specs. Comes with a lens carrying case; never thought I'd use one, but my regular camera case will carry all my kit, or the body and this lens. You will not be inconspicuous when you get this rig out; it's an OMG setup and will turn heads. There are cool and useful settings on the lens, more reading to be done. I'm learning, and it's the first time in decades where I got a lens and had to read the manual to understand how to work it! Excellent options! I'm using a monopod now, another first. After 20 minutes hand-held it becomes difficult to manage otherwise. I am supremely happy with this lens and my K-1.

    ADDED: The sample images on Amazon do not tell the story. The sharpness, resolution, contrast are all next level pro class. When I print an image on my wide printer at 13x19 inches, the image is breathtaking. I've wondered over the year how the Nat. Geo. guys get those crazy razor-sharp images... now I know. Also, the K1 image stabilization works perfectly with this beast, allowing a photographer to break the rules (shutter speed WAY too low for the focal length/light conditions) and still get images of very good to incredible sharpness.

    5.0 out of 5 stars My first favourite lens...
    Reviewed in the United States on December 2, 2016
    My favourite lens at the moment.

    Pros:

    Stunning image quality.
    77mm filter thread means moving up from Pentax DA* APS-C glass isn't as painful as it could be
    Incredibly sharp from wide open. So sharp that I have to lower the clarity in Photoshop/Lightroom for portraits. Sharpest at f5.6, which is great for telephoto landscapes.
    Focus limiter keeps AF snappy. Minimum focusing distance is 1.2m. DC autofocus is quiet and usually accurate.
    Abberations are unusually well controlled. Lens corrections are often completely unnecessary on both the wide and long end.
    Bokeh isn't overly busy, but not particularly special.
    The construction of the lens is very solid; the tripod foot release is well designed.
    The case it comes with is better quality than the usual Pentax cases.

    Cons:

    I don't see these coming on to the used market very often, so the price is likely to remain high.
    This can do a number on your shoulder.
    Fitted on the K-1, this won't fit attached to the camera across the length of my ClikElite Probody Sport + CS Sleeve backpack.

    The lens leaves me with a dilemma: I want a version of this lens in 24-70, but I'm not sure whether the Tamron designed D FA 24-70 will meet the high expectations this lens has set.
