Summary: There are so many thoughtful, detailed reviews of this lens that I really have very little to add by way of information. But I can say that I have been a keen photographer for more than fifty years, having owned an unbroken line of Pentaxes since the 1960s. In the current line up of Pentax lenses, most are good to excellent, but one or two are absolutely world class in their build, their balance, their bokeh, and of course their performance. This lens is one of them.
Superb build and image quality make this a pleasure to use

Summary: All the Pentax DA "Limited" lenses are a real pleasure to use especially for manual focus. The full metal construction and silky smooth focus action really set these apart from most modern auto focus lenses. Having a "short tele" focal length (equivalent to 105mm FOV in 35mm format) with a sub f/2.8 aperture in such a small package is remarkable. Focal length itself is a personal choice for the task at hand so I don't suggest the 70 is better or worse than any other.
Summary: I purchased this lens for my new K5 and it performs admirably! The MTF resolution is stunning and the focus on the k5 is quiet, accurate and fast On a slight downside; the screw on lens hood is a bit of a hassle to add or remove but the lens is so short that it can be left on the lens.Also the lens cap, though very nice is slightly cumbersome! Overall I love it and it has yet to come of the lens mount!
Summary: I just love the Pentax Limited lenses. Compared to Canikon, you get more for your money. Granted, Pentax is not as popular here in the US, but their lenses are really good. The build of this lens just exudes quality. And the Images - fantastic. Plus, the lens is not that big so it makes your DSLR not as intimidating. Great sharpness, color rendition and bokeh - really nice quality all around.
Summary: Objectif reçu de tokyo en trois jours en lorraine, rapidité de livraison 5/5, superbe état de l objectif, 5/5. il était comme neuf. Aucune marque d usure, je recommande le vendeur matsuiyastore.. C est mon deuxième achat chez eux. Objectifs super pour le portrait. La finition métal de ce caillou est superbe et en plus très leger.
Summary: I've gone sort of nuts buying Pentax lenses for my k5 and kx. I have the 10-17 Fisheye, 15mm Limited, 21mm Limited, 35 mm Macro Limited, 40 mm Limited, 70 mm Limited, 200mm DA*, 50mm Takumar m42 and just bought the 50mm f1.2 SMCA. I take a lot of events/street, flowers and nature shots. If you want to take portraits and candids with Pentax, this is the lens.
Summary: I am always impressed by the clarity of this lens and how nicely solid the build is. If you love to shoot a prime and long for a seriously solid metal and glass lens, the pancake series is for you! I plan on also getting the 40mm for a daily lens. This is solidly a telephoto and perhaps a bit too much zoom for the portraiture I usually do (though I did shoot an entire wedding successfully with only this lens.
