Hello !
This optics is irreplaceable on a argentic camera. On a DSLR,it is different:
In the first place, the necessary resolution (80 CL/mm) is reached only at F8.
Secondly, this objective is very prompt to flaire, and the new Pentax DA wide angles make much better (but they are also expensive) !
Colors and contrast are magnificent, as almost all Pentax primes. Nevertheless, I recommend it only for a fascinated collector!

As all the "M", this lens has a exemplary construction, all in metal. The focusing ring is well dumped and the aperture ring well notched.
The image quality is exceptional wide open, so well as on my DA70mm Limited. Its magnification factor of 2X forbids him the literally "macro" without bellows or extension rings. But it is grand for the small objects, or for reproduction of documents and slides on a reproduction stand.
In all these applications (macro included), the AF is no usefull. So, this lens has really no one defect, in my opinion...
You can see on this photo a figurine 20 cms height of pottery (a "Santon" of Provence), shot wide open for the best bokeh.

[LEFT]Hello !
I possess this lens for several years, and it was always in my bag when I photographed with 135 rolls. Regrettably, its debuts in numerics been disappointing on my K10d. As written higher, the chromatic aberrations were very too important in conditions of strong contrast.
But now, it is very different.
With the new softwares of treatment of the RAW files, we can completely eliminate them. I use "DxO Labs Pro" and I have made a special profile for this lens (A friend has done the same method with "LightRoom"). From F4, the image is very sharp, because of the reduction of the purple fringes for every micro-detail. For example, you can see the photo below of a baby mumble in Alps, shot at 10m range and wide open.
For the absence of tripod mount, it is not any more a problem either: I have found a ring, made in china for some $, which fits itself perfectly. It is a ring for a "Canon EF 100 F2.8 USM", that is stiff enough :

I also have a DA 55-300 for travel. But when the weight is not a problem, I prefer my SMC 300 F4 which has a very better softness for background.
