EF-S 250mm Lens Disconnect & Cannot Focus
1

Hi all, I've been enjoying my 55-250mm lens (+Viltrox adapter) on an EOS M50 body for over 6 months now. But recently I noticed that there are some glitches that renders the lens paralysed.

Firstly, the icons shown in the pic below will popup randomly and next the lens couldn't focus at all. AF kept showing no focus found and Manual Focus (switched via on-lens) rotating the focus ring doesn't do anything.

However, once i restart the camera, the issue resolves by itself. Happening about 2 times in the past 4 days. Any ideas what could be the issue here? Is it the body or the lens itself?

Thanks in advance !

These icons shows up randomly as if it got disconnected and reconnected.
