Re: Pentax DA 70mm Limited - Possible oily residue inside lens?

Mine, bought used 4 years ago, got aperture blades stuck too. it seems to be a frequent issue with this lens. There were no visible stains though.

All pictures shot with aperture closer than f2.8 were underexposed.

I was lucky to have it repaired 2 years ago by a local pro who did a good job for 70 €. I guess the fix by Pentax official service would have cost much more.

Now it works fine.
