Pros: Pretty much everything except AF

Cons: AF

Opinion: Where do I start, first of all I state that I use it on k70 and I was extremely satisfied from the first shots. The build quality is excellent, very compact dimensions to be a 100mm, impeccable image quality and colors (you can see that it is pentax), returns very detailed images (which is appreciated especially in macro), extremely versatile because it is suitable for all types of photography (I used it at the moment for landscapes, portraits, macro and still life and it did not disappoint me in the least) and last but not least, It is tropicalized. As a con I noticed only one thing that in my opinion is not minimally relevant since I do not use it, the AF is noisy (it looks like a screwdriver) and slightly slow compared to many other lenses but in my opinion it is quite useless, especially if you shoot macro. As far as I'm concerned, it's a lens that I absolutely must.

Pros: Sharpness, color rendering, bokeh, build quality.

Cons: Slow autofocus

Opinion: Macro objective "all round", with a construction quality perceptible in every detail. The diaphragm in my specimen at one point closed with some delay compared to the shot, so it gave, to the most closed diaphragms, an overexposure. Having the slats cleaned back to work properly even though, in my opinion and perhaps in my specimen, the diaphragm recall spring is a little weak. The optical performance is excellent, the autofocus "frullino" you know is a bit slow, but in macros it can be seen as a venial sin. I use it with satisfaction on both pentax k5 and Sony a7r2 and a6000. On the latter, not having the ring of the diaphragm, I found a craft ring that allows it to be closed manually jerky, even if it lacks the indication of the exact diaphragm. Ah, I forgot: the mechanical focus that it possesses, unlike the electro-designed ones, in macros is very welcome.

Pros: Very light, uncluttered, sharpness of images

Cons: Long autofocus because the limiter is missing

Opinion: I use it with a k1. Excellent macro lens, very light and compact and that one can always carry with you in the backpack if ever happen some strange insect or, why not, some portrait (the blurred is not bad). They have it in the macro sets at the 50 macro f 2.8 for a greater versatility of shots, although the definition of 100mm is in the specimens in my superior possession. Manual focus is always recommended in low-contrast situations to avoid confusing your photo machine with a crazy screwdriver.

Pros: returns very detailed images, bright, compact, pentax colors

Cons: autofocus without limiter

Opinion: It took me a while to appreciate this goal, at first I considered it unusable with autofocus; in fact, it was very difficult to focus even outdoors in the sunlight. The Reflex moped kept going back and forth seamlessly. Then there was the turn with the most appropriate setting of the maf on the k1 (in afc spot mode on the center points), at which point the blender is still there but much less. The optical quality is exceptional as well as the weatherproof construction, in conclusion if it had the internal ultrasonic engine and the limiter as its counterpart Tamron 90mm macro 2.8 would be much more usable , to resume insects for example. We hope that Pentax will update this goal, which in many ways is a jewel of optics and makes it adapted to the times and the competition.

Pros: Really great sharpness at every aperture; Excellent construction and valuable materials; Contained chromatic aberrations, versatility in the use of various photographic genres (portrait on all).

Cons: In my opinion one: no focus limiter.

Opinion: It happens that you buy a lens for a photographic genre and then you discover its versatility of use in other types of shots. That was my case. Taken to make Macro, as is normal it is, and used on par for portraiture. In macro, on tripod, with remote shutter release and micrometric sled it is difficult to put the autofocus in crisis. By clicking in manual focus the ring responds with fluidity and gives a certain pleasure in the use. The bokeh of the lens is in my opinion really intriguing, never nervous, but it is the transition from the focus area to the out of focus to be a true added value because it is really gradual and, although very engraved, never annoying or contrived. The surprise is to see him work well in the portrait because, although we can think the opposite, the lens behaves well within a certain range of distance from the subject, say from 1.5 Mt. Up to 4/5MT. In this scissor the portrait is amazing: The lens returns an incredible detail and I like it very much, even in this genre!. It seems to me that beyond that distance the lens does not work as well as it can do for example a 70-200 or a fixed 200 (but it is a simple impression). In this context my reduced experience has not made me notice any particular criticality in autofocus, of course it takes a little patience with subjects not really static but the children can still photograph them. It ends up being a bright tele that is worth considering also as a portrait lens because, moreover, the Pentax colors in this have a lot to say!. Simply the lens with more sharpness than my wretched optical park!!!. I recommend the purchase dispatedly.
