Crunchy Sigma 70-300mm MACRO (old vintage lens) F/4-5.6 DL SUPER

I found this Sigma 70-300mm F/4-5.6 DL MACRO SUPER at a market. Pretty banged up, but I managed to get some alright imagery with it. Full details, photography and cleaning footage can be found in video linked below.
This is a Pentax mount lens adapted to Lumix S5 with a K-L adapter.

I had one of these back in the day, one of my first Tele-lenses. It was a work horse in my bag of glass, beside my 24-70mm Canon and a "nifty 50mm".. I always loved the contrasts that came out of it in post editing ❤

what brand of lens adapter did you use?

sigma 70-300... I feel people need to properly name the stuff... if you buy used you either get one of the best or one of the worst lenses. Its a god damn gamble with sigma lenses.
