With "search skills" I was referring more to the list of all 135/1.8 lenses. And like I said, museum lenses are not of much interest to me. Big Grin  Even as second hand I would not waste money on a 2 1/2 star lens.  B)

 

The Ø relative to the Focal length is more the diaphragm diameter, I realize. But I always thought the front lens diameter should be as big as the max aperture? Not that I understand any law of optics... :unsure:
