Pros: Great all-rounder, constant diaphragm opening, solid structure, 67mm filters, Quick Shift Focus

Cons: Partially tropicalized, dial of the focus not usable in manual

Opinion: I have had this lens for almost two years. I bought it used for news. It is a good all-rounder lens characterized by an interesting focal excursion and the constant opening of the diaphragm. The double-barrelled structure makes zooming longer enough, however there are no exaggerated games. The zoom dial is very muffled so it has no spontaneous elongation problems when transposed. Filters have a diameter of 67mm which makes them less expensive. For example, the 17-70 sigma uses them from 72mm The colors are bright and saturated and the definition is good. Like all zooms made up of many lenses, it has flares in the backlights at the widest focal points. Between 17 and 21 mm you need a little attention to avoid unwanted reflections when you have the sun in the framed field. Often the fastest solution is to zoom in a bit and step back. At maximum opening it has wide-angle side chromatic aberrations at the edges of the frame. Diaphragm the situation improves but does not disappear completely. In any case, they can be solved with normal development tools. Telephoto side loses slightly of incisiveness at maximum opening, this thing can be useful for portraits. The blurring yield is good, the passages between focus area and out of focus is delicate. This makes it very usable for me but it is also a matter of taste. The speed of focus and good, not a splinter but not even a snail. The dial rotates during focus but thanks to the quick shift system it is always free to be used in manual even with the autofocus active. Used in the manuals the dial is not consistent and from the short run, this makes it inexpensively usable. A common feature of many Pentax goals of the period and of the peer range. Too bad it's not completely tropicalized. It is equipped with a seal between machine body and bayonet but not inside the lens itself. It therefore protects the machine from water infiltration through the bayonet but not from infiltration within the lens itself. In the Pentax house the alternative is the 16-85, more modern, tropicalized, with more focal excursion but does not have the constant brightness and bulkiest. If taken used it makes sense to buy it, new is to prefer the 16-85 although a little more expensive

Pros: Sharpness, utility of the focal excursion, maximum constant aperture, color rendering

Cons: Chromatic aberrations at 17mm and TA (improves little diaphragming), on K5 autofocus uncertainty.

Opinion: I got it with the K5. I regret it in some ways because I used it as a handyman, has served me very well and has never suffered the full problems of breaking SDM engine. Hard to find something of equal quality with Nikon. Very helpful, today you can choose between this and the original Pentax 16-85 which however is not fixed at maximum aperture. The colors, associated with the excellent sensor of the K5, are very beautiful and the yield of the detail also very refined. Having to find the fur in the egg the construction is not entirely convincing because of the double cam structure so when it is all extended the front lens has a lot of play and the thing is a bit scary. In mine had entered some small particles of dust for which tropicalization is not entirely reliable (that there is, although not officially stated, is a fact, given the presence of a gasket on the lens graft). A word about autofocus: coupled with the K5 is enough but my experience is that the lens is a bit uncertain in acquiring the precise focus. I mean, even on a tripod if you focus in AF on the exact same point between the two captures there is difference. But it is probably a problem of torque-camera body and AF algorithms (very old in the case of the K5). If I hadn't changed brands even going to FF I would have definitely kept it as the K5. Very often (all) Pentax products are considered to be second-order but wrongly, because their optical quality is exceptional. This lens could be the "unique lens" for someone who wants to travel light (and as Pentax APSC halves are comparable to mirrorless) maybe completing the outfit with someone of the excellent original Pentax Type 15 limited or 100 macro on the Tele side.

Pros: Sharpness, color rendering

Cons: Autofocus 70mm

Opinion: I took this in sostizione the (ugly) 18-55 as a lens to do everything to accompany my mini-canvases and 2 fixed. The difference between the two lenses is impressive and good for the eyes. The color rendering is outstanding as is the sharpness of the shots. The contrasts are good and photos require little post-production. The only comment is that sometimes the autofocus is a little hard to 70mm but just a very short focal shorten the engine immediately puts into focus. I found the best performers from 24mm to 50mm and f / 5.6 up. I would not know what to advise against it.

Pros: Excellent zoom range, light, constant aperture of f / 4, not very fast but precise autofocus

Cons: Poor sharpness to the shorter focal edges, ring maf "inconsistent" in manual, non-tropical conditions

Opinion: I purchased (second hand) to hold this view basically almost always mounted on K-S2, and how to "battle" if the purpose just fine cava. The autofocus does his duty, not the speed of light but precise, and I have not encountered problems with the SDM. The aperture f / 4 constant solves many problems, meaning they do not have to worry about the drop in brightness, zoom, though the focal shorter, say between 17 and 20-25 mm, the sharpness of the edges is not the best of life, especially at full aperture. It resolves you can count on a much better result in part diaframmando at f / 8. One downside however is not just the collar of maf is "inconsistent", that is totally lacking in strength and just touch it because it moves. And 'no doubt a nel''utilizzo problem manually, but also in autofocus you must be careful not to touch it, otherwise you may get a blurred picture. For the rest and &serious; a fairly lightweight lens, so it's not a big problem take it back for a long time. Ultimately he makes her figure, and how optical rounder is consigliatissima.

Pros: Mechanics-Sharpness-f4 fixed-Color.

Cons: SDM

Opinion: Excellent perhaps one of the best Pentax lens but unfortunately I had to deal with the "pain of SDM" and use a rubber band to fix the autofocus. Nothing tragic, but obviously it is a negative remark that I must do. For the rest is perfect. Weight fantastic colors and proves to be a good optics even under backlit conditions.
