Pros: Of course, the versatility that guarantees such an optics; the construction accuracy that I have now learned to appreciate in Pentax: at the maximum focal point, the lens stretches a lot but there is not the slightest play between the sections, the bayonet is made of metal and the graft is precise and firm; plastic abounds but of good quality and the impression of the robustness of the lens, compact enough, is perceptible; the lampshon is included in the package; there is the lock to avoid stretching the lens when you bring it facing down, which is not the case anyway.

Cons: The main thing I can move is that it is not a WR and this is a serious and incomprehensible lack: it is WR the plastics in kits and it is not an optics like this so multipurpose and also quite expensive: pentax oddities, often difficult to understand; the lampshed is a real crap : difficult to place for the next fixing, it has the very hard graft when mounted backwards in the rest position, so much so that at first I thought it was defective, and in any case I do not block it until the shot because I fear efforts too, also does not have the window for the rotation of a possible polarizer .

Opinion: I immediately start that, as in my other reviews, this is also an opinion in principle, it is not and does not want to be a technical and meticulous analysis of the exquisitely optical characteristics, which beyond my abilities, but a personal and overall opinion. I have always had sympathy for wide excursion zooms, which I find fun and practical and that I consider particularly functional to digital photography, fast, instinctive, redundant unlike the analog one, understandably more shrewd and meditated, especially for the cost of films. Moreover, nowadays, thanks to advances in lens design, these goals have achieved unthinkable performance until a few years ago and generally more than acceptable at reasonable costs. When I was in Canon, I had the Tamron 16-300, a goal, at least the copy in my possession, very valid and that gave me good satisfaction and excellent self-proof ; unfortunately, it does not exist in attack K and I therefore took this original 18-270, which is intended for the "forklift" K 50. I say straight away that I have a great time and I see that lately for this reason I am using a lot of the K 50 to which it is dedicated and all in all I really cannot complain: first of all, contrary to what is written in the characteristics reported on the Forum, the focus is not piloted by the machine but the lens has the focus engine and this , remember that it works on the K 50, an entry level, is sufficiently fast (not only in one shot) and, after making the fine adjustment to + 6, precise . Of course, such a lens should be used with knowledge of the facts and without asking for performance that it cannot give, especially in combination with a machine like the K 50, excellent in its scope and perhaps better than some of its competitors but still rather obsolete , so both give their best in good light conditions and without requiring too "speedy" AF performance , which are the conditions under which I usually operate. Let us say that overall and on average the overall optical yield is dignified at all focal points: at 18 the distortion is more than acceptable, with the increase in the focal point there are no major surprises and even at 270 one cannot complain, especially if, as I repeat, one can operate with intermediate diaphragms and low ISOs which are the conditions under which this objective gives its best; of course, let's forget the brightness, the bokeh and the definition of fixed optics but who, like me, buys this kind of lenses already knows it from the start. Finally, the price : I bought it on Amazon (not FOWA anyway) and paid it what was reported on the Reviews more shipping costs (saving almost a hundred euros compared to the store) and all in all this price seems quite centered , especially considering the large amount of focals covered. In conclusion, it is a lens that I would recommend to lovers of this kind of optics and that, used with knowledge of the facts, can be very fun and comfortable and, why not, also give some satisfaction . One last note: absolutely ungenerous (and suspect) the vote of seven and two totaled by the goal: such a lens certainly drops to some compromise but I find that, all in all, at least an eight and a half would be fairer.

Pros: It is a mono lens ranging from wide angle to tele, good construction, zoom extension block, silent and precise ultrasonic motor, good weight and size

Cons: It's a super all do, has the limits of course but all in all does his hard work.

Opinion: Constructively excellent, perhaps exaggerated as everything do 18 to 270 the jump is great, but those who buy it for sure will not seek perfection but practicality. From F 6.3 onwards both to 18 and 270 is not bad. From F 3.5 to f 6.3 of intrinsic brightness of the lens The jump is remarkable, the shutter settings in a possible zoom are unpredictable. At less than €300 I recommend it
