It's inexpensive for a macro. I see Pentax is not discouraged) Screwdriver)
Pentax continues to lose in stupor. Weaving from mdf at 30 cm and 1: 1 sbіlshennyam nі as usual, otherwise it's old-fashioned. Laova already long ago (according to modern worlds) mastered the scale of 2:1 and larger, but with manual focusing. Although it is purely for macro, then with such magnifications, autofocus is not needed.
Singingly, Pentax virіshiv less onoviti makrіk purely zovnіshno. Although the optical scheme of the troch has changed and the enlightenment of the lenses is greater today. I succumb, I can’t have such a chromatic, like that of the front. There is no intermediate focusing distance (not visible in the photo), autofocusing is provided at a visible twist. Hobit, singsongly, squeals and the front lens rotates when focusing. That is why the price is so democratic. At the current virobniks, macrocells with modern bells and whistles for 1 thousand dollars have exceeded the price.
Prote, pentaxists are fanatics of their brand, and for them, they need an update when they are stupid on the spot.
Visual analysis of Pentax.
Apparently, they decided to fix the chromaticity in this lens.
The front element is just over 3 cm in diameter and is hidden in the tube almost 2 cm deep. It is surrounded by a non-rotating filter thread with a diameter of 49 mm.
The HD Pentax-D FA 100mm F2.8 ED AW Macro is the first Pentax macro lens to feature an all-weather seal (instead of the traditional all-weather resistance) that resists dust and moisture.
Its optical formula has also been redesigned to improve image quality over its predecessor. and now includes one glass optical element
ED (Extra-Low Dispersion) and two anomalous dispersion glass optical elements to compensate for various aberrations and minimize the appearance of unwanted magenta banding. The lens coating has been upgraded to HD, which greatly reduces the average reflectance in the visible spectrum.
Like its predecessor, the lens barrel is made of metal, reminiscent of the FA Limited line of lenses.

Version 1.70 of the K-3 III firmware introduces a virtual focus limiter for the first time for Pentax. It is only available on this camera (at least for now) and only with the HD D FA 100mm AW Macro.
