Used Sony 400mm f2.8 testing
Hi all I’m a wildlife photographer. I have 200-600 and now I want to buy a used 400mm f2.8. I was testing it and I’m feeling the auto focus motor moving and a little bit of sound I can hear. Is this normal? I don’t feel that vibration on my 200-600.

That’s quite normal. It’s the OSS at work. But of course I really need to hear the sound to make sure it’s what I am assuming.
