The gentleman had come up with his favorite vintage prime replacements - the vast majority being Pentax Taks

interesting video/comparisons....

essentially, he's okay with trading modern AF/sharpness/clarity for vintage MF/character/quirks, plus saving a ton of money and weight....

Good watch and thanks for posting. No need to convert me, already new old manual focus film lenses have more character.

Describes exactly what I feel about good old glass.
And I would add more things. Just hold a Takumar and you know that you have QUALITY in your hands. You know it's been here working for half a century and it will still work for many more decades, probably for the rest of your life. Hold a modern lens and you have plastic that will crack and electronics that will die.

Why choose? IMO one should own the most enjoyable to use and best lenses of both eras though I do particularly Ike the SMCP (K) versions of the Takumars he mentioned.

Thanks for sharing.

This Video seems to ignore legacy lenses, which have the same optical elements like vintage lenses.
And some more recent lenses like D FA are constructed in the digital era but follow the design from legacy lenses.

I'd wrote some sentences about the definition/categorisation of vintage/legacy lenses here:
