This is very nice Asahi Super - Takumar 50mm f1.4 lens (#3824796) with lens caps, a Hoya UV filter, and a lens hood.  It was produced circa 1964-5.  It is in excellent condition with slight signs of use on sharp edges. The six aperture blades are snappy with no trace of oil. The glass has no fungus, haze, dust, or cleaning marks visible when examined under strong back lighting. The lens does have a yellow tint.  I tried it on my D70 and found that the auto white balance software eliminates any effect.  The auto/manual switch works fine and is marked 37801 on the back side. The focus and aperture rings feel smooth. It comes with Takumar front and rear caps, a Hoya 49mm UV filter, and a generic rubber lens hood.
