|grind down more on the side, as shown in picture|
The problem is -and I know other buyers are struggling with the same thing- is that you don't know exactly how much to grind down of the barrel. People didn't get it and I didn't, either... It's not that the person who 'discovered' this cheap wide and fast lens, Seb Farges, wasn't helpful. He shared pictures of the mod but he was not able to explain exactly why simple 'shaving off a few millimeters' didn't work. But then, upon close examination and with the help of blogger Obakesan I finally noticed what I was supposed to do: shave off the outer side of the barrel a few millimeters more, untill you reach the screw on the side.
I bought a €35,- Dremel (electric tool) to do the job and after a few rounds grinding down the barrel... tadaaaa! Infinity! I am infinitely happy with the results... I will post some footage I shot with the Pentax soon. (Note: this is not a dirtcheap lens anymore: 15,- for the Pentax, 2 c-mount adapters@ 19,- together, 35,- for the Dremel... But the Dremel is a lovely tool: I used it to slice through metal today and it lived up to the task!)
