The one with the collapsing cups built in hood. This lens is in great condition cosmetically, with well below average sign of use, looks really great. The glass is just fantastic, I can't find any issues to speak of, no haze, no cleaning marks and no fungus. The aperture blades do have oil, but it can easily be cleaned off and it has not affected anything else in the lens. I know that the words rare and hard to find are overused with vintage lenses but this lens IS rare. It is a late 1960, 90 cron in LTM mount. And it has the nicer looking and feeling sunken, matching knurling pattern on the focus and aperture rings. So, if you have an older LTM camera body, this will go right on it. Selling with original front cap and LTM rear cap. $550.00
(I can supply a factory Leica 90mm M2/M3 m-mount adapter for a small additional fee if you plan to use this on an M body)
