Pentax K-3 + Phenonix DG 2X. Got this lens for $25. Seller advertised it as Minolta mount, but his photos showed Pentax mount and a marking “P/K” on lens body (which is clearly a Pentax mount). No argument. I got it with a smile while 10 watchers were present. Minolta was out of business; got sold to Olympus. They made good lenses and cameras.
