I want to make sure you understand this very clearly...the reason why "lomography" pictures look the way they do has absolutely NOTHING to do with the film. It's because of defects in the camera.
Lomography cameras, like the Holga, are made almost entirely out of plastic. They're considered very poor quality toy cameras. They often have problems with light leaks, and soft focus and color fringing because of the poor quality plastic lens. Some people like those defects to get interesting effects in their pictures. But you have to remember that it's because of DEFECTS in the camera and it has absolutely nothing to do with the film.
There is no such thing as special "lomography film." Film is film. If you take pictures with any other film camera (a good quality film camera), it will take very sharp, clear pictures. In fact, all the Lomography brand did was just take ordinary film and just put it in a fancy box that says "lomography." It's just ordinary negative film, which you can get anywhere.
So if you load that film in your Pentax, it will take clear pictures....because that was what it was meant for.
You can take interesting pictures with a lomography camera, but you have to be very careful and choose the right subjects and the right lighting conditions, etc, and know how to use the camera's defects to your advantage.
But a REAL 35mm camera, like your Pentax, will take very sharp, clear pictures.
And by the way...there is no such thing as special "red scale film" either. All red scale means is that you load a color film BACKWARDS so that the emulsion side is facing the back of the camera. The film is then exposed through the base, and you get weird colors and the images will be backwards. But you can do that with ANY film. You don't need any kind of special "lomography" film.
