Quite often I have purple fringes in my photos, meanwhiles I was told that this is no problem of the K5 but a problem of the DA 18-135. I add two photos, one where you can see windows with purple, even green fringes. The second one has purple fringes at the corner of an hut and in the branches of an tree - but I must not explain, it is quite obvious.
I am taking my photos in RAW (unfortunately except the photo of the hut), until now I used DxO to develop the RAW-files .Since quite often the photos get worse with this software I take now the Pentax Utility, maybe I will buy Lightroom later.
Is there anybody who has similar problems with the DA 18-135?
Best wishes, thanks for your help ... Josef
Welcome to the forums.
I don't know who told you that (the highlighted part) but they were less than truthful or knowledgeable about it. I won't outright say they lied but came close to it.
Some lenses are better at handling it than others but to a degree, they will all do it given the conditions you show. The easiest way to deal with it is use a software that can pick an individual color and desaturate it.
The Gimp is a freebie that will do so. If you want to pay money for something to handle it, Photoshop Elements will do it as well I believe.
Re the K5 specifically.. The recent crop of cameras have lens correction functions in their JPG producing software that is supposed to take care of aberrations for some Pentax lenses (it will not work with non Pentax lenses) but it only does so for the JPG output of the camera. The software supplied with the camera is Supposed to mimic the functions of the camera in this respect. The 18-135 was introduced near or slightly later than the K5 IIRC and it is entirely possible that the functions are not there for that lens yet (I don't know that for a fact though).
