Hello all, I recently got a Sigma 500mm f4.5 but have noticed a huge issue with focus since I had it. AF just doesn't seem to work properly, both in the viewfinder providing just off shots and the Live view focus just will not even work. It flashes red and stops after racking. I have tested this against my 70-300mm as well as all other lenses and all work fine. I have just taken these images of our local cats in the exact same position, with identical settings, the sigma just seems off to me.
P.s here are some additional shots that were easy to capture, but didn't seem to have the ability to focus on the subject. Any other lens I've used in these situations worked perfectly fine.
