Pros:Aesthetically beautiful, especially the "silver" version I took; impeccable construction: an aluminum jewel reminiscent of the objectives of the past, a very practical lampshed; even the package reserves a pleasant surprise with the leather-like bag that maybe we will never use but it is very nice. Of the cap (which I did not even notice) I can not care less as in front of the front lens I immediately put, as always, a UV filter. Tiny and light, mounted on the K50, for which I took it, it constitutes an agile and very compact combination.
Cons:Perhaps it is precisely the small size, which makes it a little difficult to assemble and disassemble offering a very small grip surface and then the inconvenience, which do not lose at Pentax and is one of the many incomprehensible choices, the red alignment dot for assembly (which was once even a ball, red or white , embossed and on the outside of the barrel!) well hidden on the inner face of the graft flange, difficult to detect and that forces you to rotate the lens in your hand until you spot it, a real stupidity ! The fact that, again incomprehensibly, it is not tropicalized, it has already been said.
Opinion:In addition to the two macros, it is the only fixed lens I have, since I am a convinced zoom user. It is a lens That I took especially for the K50, to be used in pairs with the 18-270, and it was a bit of a must, not offering Pentax a compact wide zoom, low cost and not fish and wanting me to be able to go below 18 mm. Here too, my opinion is in principle, not purely technical or particularly in-depth from an optical point of view but simple considerations or surveys made "de visu". The objective optically I like: it does not present particular criticalities (flare, excessive perspective deformation) and since in general such a lens is used to intermediate diaphragms, it is forgiven a very slight optical decay at the edges at full opening. The MAF is fast and does not seem particularly noisy to me (but I have used it outdoors so far); the detail offered by this lens is excellent and so the colors and ultimately, with these peculiarities, I could not ask for more. It's not particularly cheap (paid in store more than 500€!) but considering optical yield, materials and construction, all in all it can stay there.
Cons:Not bright, autofocus a bit noisy, sharpness at the edges not at the top at T.A., screw cap impractical
Opinion:Bought used but in terms of the new, I appreciated right away the compactness that allows him to go virtually unnoticed, especially in the version "Black" like mine. Compact but sturdy, all in metal, including the built-in hood, of an infinite comfort because you just need to extract it from the front and is immediately ready. On the other hand the front cap is screw, impossible to accidentally come away but it is rather cumbersome to put and remove. It is not bright, but the compactness has its own price and however being a 15 mm you have great margin with the time of safety and with a little ' attention takes home the photo even with 1/5 sec., and also the depth of field is huge even at F/4. At full aperture the sharpness is good in the center, less at the edges, but just close one stop and the situation improves decidedly on the entire frame, to reach the top at F/8. The autofocus is accurate and fast enough, although it really does not have to work so much view the above-mentioned remarkable depth of field (with good light just put at F/8 and in hyperfocal), but it is noisy and in environments like theatres and museums it makes you feel. The price is not really popular but in the end there is, given the robust materials and optical qualities, and if you are fortunate to find a good used is definitely worth buying
Opinion:In my furniture I was missing a wide-angle. Usually I am shooting of wild animals or do macro. For some landscapes I used a compact Canon. I prefer a fixed focal length, so I decided and I ordered my Pentax 15 mm provider. I had to wait over a month to have it, is not like the one in the photo, mine is black. I fully agree with what reviewed by Bigisbetter. I found a little 'crowded out when I discovered that the front lens cap screw was, new to me. In fact it is inexplicable choosing Pentax not tropicalizzare this goal, the cost was probably there in the list price that seems to be more than 600 €.
Opinion:A tiny angle that is well suited to landscape photography. It 'an f / 4 so not particularly bright, but in the landscape are usually employed diaphragms fairly closed to maximize sharpness and pdc. In terms of pure clarity this light gives their best between f / 5.6 and f / 8. At f / 4, the center is good but the edges are a bit 'soft, already at f / 5.6 the edges nettamente.rnBuoni improve colors and contrast. Even the resistance to flare is not bad. Overall, the optical performance, while not record-breaking, is ottima.rnI great merits of this view are building really excellent aluminum, tiny size, weighs less than 2 ounces, integrated retractable hood. The only drawback some 'inexplicable, even given the considerable price, is the lack of weather sealing, when Pentax provides tropicalised even plasticotti from 18-55mm kit.
