I was lucky to find this guy at a garage sale at 500$ and I immediately had to jump before someone else did. It was worth it. I had my first great white. It was super heavy, but what is expected when you see a long focal length paired with an aperture of "2.8". Immediately, I loved the IQ. DOR is sublime and it is tack sharp. Surprisingly good at portraiture, great for nature, but very difficult to use in sports due to MF. However, when photographing the eclipse, I experienced very harsh CA along the edges of the moon.
Was it worth the 500? Heck yes! But I would not buy any listings that are above 1250$. It is good, but not that good.
The optical quality was disappointing for an L lens. Very little if any CA but color quality is weak, I'd call it 'pastel' on a good day.
