Originally posted by BigMackCam I'd be more concerned about the "full of dust" and "professionally cleaned" claims than the tiny optical damage. How did it get so full of dust?? And who was the "professional" cleaner... a Ricoh / Pentax service center, local camera and lens repair shop - with (or without) specific knowledge of the lens, or a competent hobbyist? It's one thing to disassemble, clean and re-assemble a simple old manual-focus prime lens... but quite another to carry out the same service thoroughly and competently with an optically and mechanically complex lens such as this.
I agree I also wondered how a lens could get that dirty. If the seller is not lying, it was a repair shop :
Réparation Photo | Réparation Horlogerie | NIKKEN FRANCE Originally posted by BigMackCam If you decide to buy it (and 160 euro is a very attractive price), just make sure you have the ability to return it for a full refund if there are any problems. Then, when you receive it, test it fully. Try it out at all focal lengths, view the images at 100% reproduction to look for de-centering and any other obvious issues, use it in AF and MF modes, check that it focuses to infinity and minimum focus distance, and moves back and forth throughout the entire range without difficulty.
Unfortunately, returns are not allowed by the seller, but I did buy it nonetheless, with the ebay assurance just in case. Of course I'll check everything you mentioned. I'll keep you all informed.
Let's hope I will have more luck than the last time when I tried to buy a DA 16-45 last week, pristine-looking in picture, with indeed very clean front and back lens, but with the aperture level bend, the A-pin missing on the mount (there was a hole) preventing aperture control from the body and a loose screw floating inside the lens sometimes blocking the zoom ring. At least, I'm pretty sure aperture level won't be a problem with the PLM.
