Dear Everyone,

This afternoon I was trying to take pictures of small birds and my R5 with the RF100-500 mm lens would in certain situation focus out to infinity and then it was very difficult for it to refocus on a small close up subject (e.g. a Chickadee). This did not occur with all background, but appeared to occur more frequently when the background had high contrast and the foreground had less contrast.

If anyone has found a solution to this occurrence please share and thank you in advance.

Cheers,

John
