I've recently just acquired this lens pre-loved about 9 months ago and I have to say that's it's become one of my favourite. It recently developed an issue (or maybe it's always been there but I never noticed).
When the focus ring is at infinity, the distance on my A7R3 reads 2m and when I rotate from infinity to MFD, it moves towards 0.3m and right around the 0.31m mark on the lens barrel it pops to infinity and stays there for the rest of the way.
Is this normal? My only concern is whether it is negatively affecting the IBIS and essentially overcorrecting. I have for the moment turned off SteadyShot when I use this lens and just shoot at a high enough shutter speed. It does seem to affect my shots at around 1-2m but this is an informal test handheld so it's terrible evidence.
Sending it back for service isn't really worth it as for about the same money, I could just buy another 2nd hand one.
Ideally, I would like some benefit of IBIS so I was wondering if setting it to manual and 60mm focal length would help? Does that setting then ignore the focus distance and not factor in lateral shifts?
