Pros: Sharpness, construction, overall image quality, size and weight

Cons: Autofocus, lack af limiter, autofocus, autofocus

Opinion: The lens is fantastic, very sharp, I had it for more than a year between 2017 and 2018, I still remember how much I could crop without worries ... Even the colors, the blurry and any other optical feature are really at the TOP, too bad for the engine af... it made me sell all the Pentax kit from despair, wildlife being my favorite genre. I got to try another one recently and the autofocus (on the same machine, the k3) worked better, but always in hiccups...

Pros: Sharpness, construction, tropicalization

Cons: Missing stabilizer

Opinion: I say that I am passionate about landscape and naturalistic photos and that my opinion comes from these kinds of use. The clearest lens ever had. Well built, robust and interperie-resistant. Sharp to TA and becomes a razor already from f4.5. Used on both KP and K1-II. On FF sensor we have sharpness up to 100% of the photo. It lacks stabilizer but thanks to the stabilized machine bodies I managed to shoot anyway at 1/200 freehand getting sharp photos. Nice blurry and discreet AF. One of the best purchases ever made.

Pros: Sharpness, blur, color, price

Cons: Nothing

Opinion: I consider it one of the best lenses ever built by Pentax, I have had the opportunity to try it for years and it is still a lens from which I can not separate myself. Simply because it is of truly excellent quality. It also Works properly on the K-1 and is multichangeable although it has to be used in this case, but they are in this, crop mode for not vigneting. Another point in its favor is that compared to the new Octice full frame is less heavy and cumbersome, not a feather but portable without problems.

Pros: Exemplary sharpness, excellent construction, tropicalized, excellent value for money

Cons: Autofocus not up to par

Opinion: I have this optics relatively recently but I have already tried it in different situations (birdlife, panoramas, car races), and I can only say it well. In particular I was surprised by the sharpness, very good already at full opening and that becomes a blade closing by a stop. It doesn't get much worse by closing at most but its top is around f/4.5 - f/5.6. Very few chromatic aberrations, and only at f/4 in high contrast zones, easily eliminated in post-production. Another positive thing is the construction: robust, well-balanced, infuses safety and immediately gives the impression of an object made to last, and the fact that it is protected from dust and splashes of water only confirms this impression. The lampshade (with the comfortable window to rotate the polarizer without disassembling it) and the bracket for the tripod are also well made. Then it is not too heavy and the handling is not bad at all. Of course, grafted on the K-3 you get to almost 2 kg of stuff and for the long sessions I recommend at least one monopod. The color rendering is very natural. The main flaw is the autofocus, not up to the other great features of the lens. It is very precise and hooks the subject well, but struggles enough to follow it if it is in rapid motion. In track races, in some cases I found manual focus on one point more effective and wait for the car to pass by. Perhaps an AF limiter would at least partially solve this problem, which is quite typical of the SDM. There is good that, at least my specimen, does not suffer absolutely from front or back-focus. I took it out of the box, grafted it on to both the K-3 and the K-S2, and found it was perfect enough. So apart from the autofocus, I think it's a really good lens, which I highly recommend. It's worth every penny of its price.

Pros: flawless construction, sharpness, color rendering

Cons: for me no

Opinion: I wanted so much this fixed tele which is now part of my kit. I have not tried optics of other brands, but this Pentax DA * is close to perfection. Sturdy, solid, great quality. Worth all the money that it costs. It 's like giving doping to my Kr: it allows me to do sports and aviofauna photos that give me a lot of satisfaction. The lack of an AF limiter can not find it very uncomfortable and the speed AF good judge (I will update the review to the change of the main unit). F4 max is fine in every situation in which you use this external lens (according to my opinion). The fineness of the produced pictures do not even need to dwell. Combined with a camera body type k3 I think is phenomenal.
