Opinion:If this lens had a height autofocus it would be first prize in its category. I did not want to take a vote for this because I often use a manual focus and I must say that it was love at first sight. A unique design and still unimitated, does not resemble any other Pentax lens or other brands. What about, it's one of the first I bought of the Pentax and I don't really think about giving it away. On the K-1 then found its right size, that full frame. It is very valid not only for the macros and all in all quite bright, resistant to rain and bad weather... what else can you want?
Opinion:I added 10 of the evaluation, the limits of the AF - strictly speaking - should preclude the maximum rating of this lens, but over the years I have had the opportunity to try macro lenses of other brands and there is an aspect - for me fundamental in a macro lens - that makes this Pentax lens irreplaceable: a blurred so softly blurred I find it only with this 100mm, a passage so soft between fire and out of focus I get it only with him and then when a lens becomes irreplaceable as you do not to give it 10? rnOf course then has the advantages of Pentax optics, the build quality, the incredibly small size to be FF optics, the tropicalization that makes the pair with the tropicalized cameras of the brand.
Pros:Even just looking at it, a small and perfect masterpiece of mechanical: very compact, all-metal, the first impression one has is of extreme robustness and efficiency; small but not lightweight, fits in every bag and, valuable not to be forgotten, is a WR: with its wheel flange is perfectly adapted to the traditional qualities of tropicalizzazionerndelle Pentax cameras.
Cons:As expected, given the presence of the "PTO", autofocus, controlled by the machine and therefore not quick and peremptory as that of optical with internal AF motor; But beware: even if it takes a fraction of a second longer when hooks does it with surgical precision, without wishing to be considered, however, that often, in macro, the focus is done manually, and perhaps with the machine on the stand; attention also to the ring MAF: AF is switched off and must be careful not to hinder the movement with his hand, something relatively simple because the same ring has moved far forward, so close to the front lens.
Opinion:Focus aside, it is a superb goal, that if the play on par with the best counterparts of competition: the constructive accuracy beyond (I open a parenthesis, important for me: I have not yet happened, with Pentax, the find a lens less than perfect in terms of construction: no games between the rings, the focus rings shaky, zoom too hard or too "loose", that move independently of lengthening or shortening depending on the location of the machine), the ' lens is dry and sharp as you would expect from a glass you can say "specialist" and, though this model allows it, also ideal for portrait, facilitated in this by the generous aperture of f / 2.8.
Pros:sharpness, waterproof, super macro, light and compact
Cons:In low light the fire does not hook forcing the lens to long commutes back and indietro.rn
Opinion:This lens is a little little considered but has the merit of being a perspective professionale.rnLa sharpness is higher regardless of the diaphragm, it has a bit of glitches in the event of rnfocheggiamento the night or in dark places, but also in the case of macro with shallow light, it resolves the quick shiftrnoppure manual.

Pros:Risolvenza micro contrast and exceptional compact and weather sealed, all-metal construction
Cons:Missing a limiter Focus
Opinion:This lens is a pleasure to use and hold built entirely of metal with a black finish and a ring focus fluidissima.rnLa compactness means that you can easily bring in the bag along with other lenti.rnConsiglio also ' Use for portraits, activity that lends itself exceptionally although excess sharpness even at f2.8 means that you have to spend a little 'more time in post production !!!
