Pros:Excellent yield (sharp, homogeneous, contrasted and with good colors) and excellent construction (tropicalized and motorized)
Cons:The starting 28mm, you could make the effort to go down to 24mm.
Opinion:I bought this used lens in December 2022 to give a worthy "battle" companion to my K-1: I usually prefer to use fixed and / or vintage lenses (in fact for a year I had used an old, but performing, Variozenitar 25-45), but there are situations in which the modern zoom and autofocus definitely simplifies shooting operations. The 28-105, even as the only lens, is the ideal companion when you want to carry little weight around or when you go to photograph a place that you do not even know "in the abstract", or when the physical conditions of shooting do not allow an easy change of lens as needed. The yield of the 28-105 is that of a perfect modern lens: clean, sharp, contrasted, homogeneous throughout the image. The use is easy, the autofocus is ready and silent, the rings are wide and well frictioned; Excellent the usual hood with window to turn the polarizing filter. Tropicalization is a priceless plus on a "low-end" lens, which allows you to use it without hesitation in any weather or field situation. I've only had it for 4 months, but it has already become indispensable.
Pros:Sharp at any aperture (solves the sensor of the K-1). Tropicalized. Second-hand price.
Cons:It starts from 28mm and not 24mm, 4mm make the "difference" in landscapes.
Opinion:I bought it for 350 euros used by a loyalist of the brand. I needed a low-cost original lens for my K-1, since until then I had only put on Vintage lenses. I state that the "HD Pentax" treatment of this model, makes it contrasted and with "lively" color rendering. Sharp from the edges to the center is a lens that for "resolution" does justice to the severe sensor of the "Kappona". In the end, however..., having shot for almost a year with lenses -A, Super Takumar of the 70s has collected its duty: the "perfect" 28-105 seemed to me without "soul. If it had started from 24mm I would have kept it, but surely price and weight would not have been the same. That said, I recommend it for dispassionate shots without particular pretensions. It is a digital lens without art or part.
Opinion:The sharpness is really good combined with the sensor without AA filter of the K1. The autofocus is fast and quiet. Too bad that my specimen has ceased to focus when set above 35 mm. Used very little and still under warranty... We hope for assistance. Great disappointment gave me up at the beginning of a photographic journey.
Pros:Small, light and very nitodo. Very quiet focus and in my opinion very fast, no means...
Cons:For the moment nothing
Opinion:After over a year of use I did not find defect any kind. Modest brightness, but in the price range in which it falls I do not think you could want even high brightness... I feel great, and I like it as much as it makes even in colors; not too bright, but beautiful (in this sense I used in the past a K50 with 18/135 and it was an explosion of contrast and live colors...). Bought because when I bought the k1 was not available in store on 24/70, but I am satisfied! Sometimes he misses the 24, but that's fine. Ah, tropicalized, sorry if it's cheap. It has already endured heavy rains and snowfall. Cheap filters.
Cons:I would have preferred to depart from 24mm and it should cost something less
Opinion:Firstly, the optical yield: excellent in the center, the edges are not less and it is at the sensor of the K1; The definition is therefore far more than satisfactory and the chromatic rendering is also of a good standard; I have not detected any significant AC or flare phenomena; The single MAF on the outside is, in my humble opinion, comparable to what I used before moving to Pentax, in low light is not as fast but the situations in this case can be extremely variable and therefore to be assessed on a case by case basis. No front/Back focus phenomena. On the materials nothing particular to say: talking about "plastic" is, more than reductive, unappealing and does not seem the case: it is anyway of components of excellent quality (very pleasant the central band in rubber worked "diamond" very old fashion) and, Especially, assembled in an excellent way; Even the resistance offered to the focal variation is centered; The lens of course is WR. It is ultimately a more valid alternative to the more demanding 24-70 f/2.8; A little too high the cost, a hundred euros less and the price/performance ratio would be really optimal. One final consideration: the average vote obtained from the optics of 7.2 is truly ungenerous and indeserved and raises strong doubts about the reliability.
