i dont think this lens is automatic so you have to adjust it manually

You see plenty of these for sale second hand, I can't believe they even make a 2 x convertor for it. you will need a lot of bright light, or a very long exposure to record anything with it. Most people think they are for taking images of light filaments at long distances, pass it on and get a sigma 120-400 lens.

Hi Welcome to the forum.
This is a slow manual focus lens, to get the best out of it you will need to put it on a tripod, give it a long exposure.Good luck... Graham
